2. ELECTRICAL FEATURES
2.1. Electrical parameters
The iLC PRO control gear with eSMART technology has a very extensive operating area, perfectly adjusting the
operating point required in the design of each luminaire and each lighting system. The result is full flexibility, easily
adapting to the continuous and fast evolution being experienced by LED technology lighting.
The operating area of the drivers is dened by the maximum and minimum load voltage that can be connected, by the
maximum and minimum output current that can be programmed and by the maximum working power.
The operating point is dened by the maximum voltage of the LED module to be connected and the current which it
is going to supply. This operating point must be within the operating area of the selected driver.
In the iLC PRO family, the operating area of one model partially overlaps with that of the higher output model, ensuring
a continuity that effectively responds to every operating point. When the dened operating point falls within the
operating area of several drivers, selecting the device with the lowest assigned power will provide it with the best
electrical output values in terms of THD, power factor and efciency; while selecting the device with the highest
assigned power will provide a lower working temperature and as such, a longer service life. Generally, if the luminaire
has a good thermal design, the rst option is usually the recommended selection.
The iLC PRO control gear with eSMART technology permits a wide range of the supply voltage that, in addition to
becoming a solution suited to a host of installations, guarantee stable and reliable operation in the face of fluctuations
in the values of the mains grid voltage.
In terms of efciency, the power factor, THD and dimming range of the iLC PRO drivers are positioned in the high
performance segment of the lighting sector.

2.2. Electrical insulation
Control gear with eSMART technology has been designed in accordance with the EN 61347-1 and EN 61347-2-13
safety standards for double or reinforced insulation against electric shocks resulting from contact with accessible
parts.
The insulation between the primary and secondary circuits, as well as between every circuit and the functional earth,
is set out in the following table:
Functional
earth Input voltage DALI 0-10V LED module/external NTC / STELARIA
Functional earth XDouble Double Double Double
Input voltage Double X Main Main Double
DALI Double Main X Main Double
0-10V Double Main Main X Double
LED module/external NTC / STELARIA Double Double Double Double X
NOTE:
When the devices are built into luminaires, the cabling between the different components must observe the insulation class for
which these lighting xtures have been designed, as well as comply with the EN 60598 standard.

www.elt.es

3. THERMAL CHARACTERISTICS AND LIFETIME
The thermal operating conditions of the control gear are a critical factor for its lifetime and for the LED street lighting
system into which it is integrated. This is why an understanding of the factors and parameters relating to this aspect
is essential.
Control gear equipped with eSMART technology has been designed to offer maximum performance with the best
thermal efciency.
Once the drivers have been integrated into the lighting system, the thermal efciency and lifetime depend on factors
such as the connected load, luminaire design, its capacity to dissipate the heat generated inside the unit and the
relative position of each of its components.
3.1. Temperature inside the casing (tc)
The parameter to control in order to ensure correct operation and life expectancy is the temperature inside the casing
at a point called tc. The tc is a point of reference that represents the conditions under which the driver’s internal
components are working. Particular care must be taken to ensure that the maximum limits specied for each model
are not exceeded.
The simplest way to measure the temperature at this point is by means of a thermocouple attached at the place
indicated on the casing of each driver once thermal stability has been achieved.
NOTE:
The eSMART drivers from the PRO range incorporate a diagnostic mode that indicates the internal temperature value of the driver.
This is for guidance purposes only as it does not necessarily coincide with the tc value.
3.2. Ambient temperature (ta)
The eSMART drivers have been designed to be able to operate within a very wide ambient temperature range. The
maximum ambient temperature limit depends on the operating point, the value of the connected load and, largely, to the
design of the luminaire itself and its ability to dissipate heat outwards.
The maximum permitted ambient temperature for control gear can serve as a guideline or an indicator of the
conditions under which that device is able to work, however must not be used as the control parameter to guarantee
its estimated lifetime.
With the aim of ensuring reliable ignition in ambient temperatures of less than -25ºC, the drivers power up gradually,
applying a start-up process that lasts for a maximum of 10 seconds. Gradual start-up takes place irrespectively of
the driver conguration.
3.3. Lifetime
The eSMART control gear can achieve up to a 100,000 hour lifetime depending on the working temperature at point
tc.
NOTE:
Thermal data and the lifetime of each model can be viewed on their corresponding data sheets, available for download via the ELT
website at www.elt.es/en

www.elt.es
4. PROTECTION
The eSMART technology control gear from ELT is equipped with internal protection to ensure that the drivers and
every component of the luminaire in which they are installed operate correctly.
4.1. Short circuit protection
In the case of a short circuit in the load terminals, the driver disconnects the power and goes into protection mode,
in which it remains as long as the fault continues. This protection automatically resets so that when the short circuit
is resolved, the driver comes out of protection mode and reconnects to the power supply.
4.2. Overload and open circuit protection
In the event of an overload or open circuit, the driver disconnects the power and goes into protection mode.
When occasional situations of overload or open circuit are identied in the output terminals, the protection mode
automatically resets. This means that once the fault is resolved, the driver comes out of protection mode and
reconnects to the power supply.
Should overloads or open circuit events repeat over time with a high level of frequency, or if such events persist,
protection mode will not automatically reset and it will be necessary to disconnect the mains power for at least a
few seconds.
If the driver is connected at a load lower than that permitted for the operating area, it will flicker as long as it remains
connected.
4.3. Thermal protection
Drivers with eSMART technology benets from thermal protection, meaning that when a temperature excess is
detected, the power supplied is reduced or even switched off.
If, under normal operating conditions, the temperature at tc exceeds its maximum permitted value by 5ºC, the driver
will reduce the power supplied to the load by 25%.
If, during power reduction mode, the temperature at tc continues to rise until it exceeds its maximum permitted value
by 7ºC, the driver disconnects the power.
While in thermal protection mode, having reduced or cut off the power, if the temperature at the tc reduces to 6ºC or
lower than its maximum permitted value, the driver will return to its initial normal operating mode.
This process is illustrated in the flowchart on the following page:

www.elt.es
10
4.4. Out-of-range mains voltage protection
In the event of a low mains voltage value that is between the permitted minimum and the brownout value, the driver
will remain on. If this situation continues over time resulting in over-heating, the driver will reduce the power supplied
to the load and even disconnect it in extreme cases.
In the event that a mains voltage value is less than the brownout value, the driver switches itself off for protection.
In the event that a mains voltage is above the maximum permitted value, the driver will remain on, generating stress
on its internal components and potentially affecting its lifetime. Possible adverse effects are increased the greater
the value and the longer the time that the power surge continues.
Even though the drivers are able to withstand power surges of 380Vac for 2 hours, extreme care must be taken to
avoid this type of situation.
4.5. Shock wave protection
Drivers equipped with eSMART technology from the PRO range are designed to offer improved protection of the
supply terminals against shock waves such as those caused by radio storms. They benet from levels of protection,
in both differential and common modes, that are higher than the minimums dened by the immunity requirements
for lighting equipment under EN 61547.
▪Protection in differential mode (L - N): 6kV / 3kA
▪Protection in common mode (L - Earth / N - Earth): 8kV
If higher levels of protection are required, external devices can be added to the luminaire or to another point in the
street lighting installation.

5. FUNCTIONALITIES
5.1. Adjustable output current (AOC)
The adjustable output current (AOC) is a feature that congures the nominal value of the output current from a driver
with eSMART technology.
The output current value selected is understood to be the nominal value used to achieve 100% of the light level in any
of the selected dimming modes that can be programmed within the entire permitted range.

www.elt.es
12
5.2. LED module thermal protection (MTP)
This feature activates a thermal protection for the LED module, controlling its temperature via an external NTC
located inside the module itself.
It has to be congured so that the driver regulates the output when the reading provided by the external NTC indicates
that the temperature at the tc point of the LED module has exceeded the maximum value that guarantees its expected
lifetime. The parameters to be dened are the “start temperature”, the “stop temperature” and the “dimming level”.
The “cut-off enabled” option can be activated which makes the driver turn off the LED module if the read temperature
exceeds a value dened as the “cut-off temperature”.
In the event that the LED module switches off because it has reached the “cut-off temperature” value, the driver
automatically switches back on at the maximum dimming level when the read temperature is 5ºC below the “start
temperature”.
So that the values of the measured temperatures are correct and can be handled by the driver, an external NTC has
to be selected and used from one of the following four commercial references:
▪NCP18XH103F03RB, 10k, 1%, 0805, MURATA.
▪NCP15XW153E03RC, 15k + 390R series, 3%, 0402, MURATA.
▪NCP18XW153J03RB, 15k, 3%, 0402, MURATA.
▪NTCS0805E3153GMT, 15k, 2%, 0805, VISHAY.
WARNING: connecting active signals to the external NTC terminals could run the risk of a breakdown.
Cut-off temperature deactivated Cut-off temperature activated

www.elt.es
5.3. LED module constant lumen output (CLO)
This feature allows a gradual increase curve of the output current over time to be dened for the constant lumen
output depreciation of the LED module.
To correctly use and congure this functionality, the depreciation curve of the LED module lumen output to be
supplied must be known. This curve can differ for the different LED modules on the market and depends on both the
operating point and the thermal conditions under which it is working.
Based on this information, a table can be dened to incrementally assign an output current value for each operating
interval, so that the loss of LED module lumen output during that period is compensated.
The output current value can be assigned in increments of 1% within a range from 0 to 100%, where 100% is the value
dened by the AOC. The intervals can be congured in steps of 500 hours.
To synchronise the compensation curve congured by the CLO with the actual lumen output depreciation, the MOT
parameter, “the LED module operating time”, must be entered so that it coincides with the actual operating hours of
the LED module.
WARNING: The MOT value is also used for the EOL functionality.

www.elt.es
14
5.4. LED module end-of-life alarm (EOL)
This functionality provides a visual signal indicating that the LED module has reached the end of its lifetime and as
such, its replacement is recommended.
To congure this functionality, the number of hour’s life expectancy for the LED module has to be selected in addition
to the actual time that the module has been working.
The driver will make the LEDs flicker for 3 seconds after power-on when the actual operating time reaches the
expects lifetime, after which it will continue its normal operation.
5.5. Programmable start-up time (PST)
This feature is able to congure a smooth and pleasant start-up, avoiding an abrupt sensation when the street
lighting switches on.

Activation of the PST functionality can only take place in the ON/OFF, 1-10V and 0-10V modes. Start-up duration,
from the moment the mains voltage is switched on to achieving 100% output current, can be congured between 3
and 600 seconds, in increments of 1 second.
NOTE:
Conguring a smooth start-up using the PST functionality does not reduce the peak and width values of the inrush current.
5.6. Monitoring parameters and events
Control gear equipped with eSMART technology records numerous events in its non-volatile internal memory along
with the maximum and minimum values of different parameters and operating times in different modes, relating to
the control gear itself as well as to the LED modules its drives.
Real time data recorded and the parameters can be monitored by the user via the iSOFT conguration software and
by means of the STELARIATM remote street lighting management system.

www.elt.es
16
6. DIMMING METHODS
Control gear with eSMART technology is able to select the most suitable dimming method for each application. The
choice of a specic dimming mode activates its conguration parameters and deactivates other dimming methods.
Dimming is achieved through the amplitude modulation (AM) of the output current, obtaining flicker-free light at each
regulation point
The main features of each method are explained below.
6.1. DALI mode
DALI (Digital Addressable Lighting Interface) is a digital and addressable communication interface for lighting
systems, standardised in line with EN 62386 that guarantees the correct operation between devices produced by
different manufacturers.

17
www.elt.es
Communication between programmable control gear and other DALI devices (sensors, control panels or other
peripherals) takes place via two cables and is two-way, enabling dimming, conguration and consultation commands
to be sent.
By selecting this method, the user can choose between a logarithmic or linear dimming curve.
All the information relating to this dimming system is explained in the DALI standard in line with which the eSMART
technology drivers have been designed.
6.2. 1-10V / 0-10V mode
This dimming system is able to vary the light flow by means of an analogue control signal that reaches the drivers
via an additional two-wire control line, whose positive and negative polarity must be observed when making the
connection.
This one-way system, in which the control information only flows from the controller towards the control gear, is not
addressable, given that every device connected by cable to the control line reacts to a set point.
The analogue control signal is a continuous voltage level within a range from 0V to 10V. This signal can be obtained
directly from an active control device (analogue control cards or power supply sources) or indirectly from a passive
control device (variable resistance or potentiometer) through which the output current generated by the devices in
their control terminals circulates.

www.elt.es
18
To ensure that these active control devices work correctly, they must have the capacity to absorb a quantity of
current greater than that generated by all the connected devices together.
Where a potentiometer is used for regulation, this device must have the resistance value indicated in the electric input
parameters of the driver. When various devices are going to be connected to the same potentiometer, the following
formula has to be applied to calculate its resistance value, adequately sizing it in terms of the power to dissipate.
The ratio of the resistance value of the potentiometer compared to the control voltage level and the light regulation
level generated is not linear, which means that logarithmic control potentiometers can be used to improve the
dimming experience.
The use of active control elements that generate the analogue 0-10V signal is the recommended option over the use
of passive elements such as a potentiometer in cases where stricter control is required over the regulation point or
where the device is expected to work in extreme temperature ranges.
The response of the 1-10V dimming differs slightly to the 0-10V.
In 1-10V dimming, the maximum dimming level is obtained by leaving the control terminals in open circuit or with
a signal equal to 10V. This is the 100% level and cannot be congured. The minimum level, however, is obtained by
short-circuiting the control terminals or via a signal lower than 1V and this may be congured.
0-10V dimming is almost the same as that for 1-10V except that the drivers can enter into standby mode when the
control terminals are short-circuited or with a signal that is very close to 0V. The standby output is guaranteed for
values higher than 1.5V.
Within the temperature ranges at point tc between -40ºC and -30ºC the driver will remain at the maximum level
regardless of the signal in the control terminals. However, the driver will respond to the set points as it enters standby
if the selected dimming mode is 0-10V.
NOTE:
Drivers from different manufacturers may produce different responses to the same control signal value.

6.3. ActiDIM mode
The ActiDIM operating mode is a stand-alone dimming system that simulates astronomical behaviour to provide
energy saving without the need to wire in a control line.
The automatic dimming algorithm controls the times at which a change of light level has to take place. It takes as
a reference the average night time duration point, calculated based on the average of the last three nights. The
duration of each night is dened as the time measured from when the street lighting is switched on to the time it is
switched off.
NOTE:
When the lighting is switched on for less than 4 hours (for example, to carry out maintenance tasks or during power outages) and in
cases where it is on for more than 20 hours, the control gear does not memorise that period as a ‘night’ and therefore does not take
it into account when applying the ActiDIM calculation algorithm.
This system is able to congure different dimming proles, selecting up to maximum of 9 levels, their value, the
duration of the transitions and the changes between them.

www.elt.es
20
Tourist ActiDIM mode
This option is recommended for situations that require total or partial deactivation of the dimming prole established
by the ActiDIM operating mode during the night over one period of the year, dened on an approximate basis, in a
specic location.
For example, in summer, the initial dimming parameters dened for the period up until midnight are cancelled, so
that the driver operates at maximum power up to that point, before continuing to follow the prole established under
normal ActiDIM mode.
This function offers added value to the standard ActiDIM mode, as it allows the luminaire to operate with two different
behavioural patterns with no need for control cabling to change from one mode to the other.
