2. ELECTRICAL FEATURES
2.1. Electrical parameters
The iLC CORE control gear 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 terms of efciency, the power factor, THD and dimming range of the iLC CORE drivers are positioned in the high
performance segment of the lighting sector.

2.2. Electrical insulation
The iLC CORE control gear 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:
Mains 1-10V Functional
earth LED module Accessible parts
Mains XBasic Double Double Double
1-10V Basic XDouble Double Double
Functional earth Double Double XDouble Double
LED module Double Double Double XDouble
Accessible parts 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.

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.
The iLC CORE control gear 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.
3.2. Ambient temperature (ta)
The iLC CORE 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.
3.3. Lifetime
The iLC CORE control gear can achieve up to a 100,000 hour lifetime depending on the working temperature at point
tc.

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

4. PROTECTION
The iLC CORE drivers are equipped with internal protection to ensure that the they 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 goes into hiccup mode (power-on retries), in which it
remains as long as the fault continues. This protection resets automatically, so that when the short circuit event is
resolved, the driver comes out of protection mode and the power supply restarts.
4.2. Overload and open circuit protection
In the event of overload, the driver goes into protection mode, where it remains for a specic time depending on the
severity of the overload. The protection mode maintains a constant output, making it impossible to perform any type
of programming while it is in this mode. When the overload exceeds 150V, the driver goes into hiccup mode, where
it will remain as long as the fault continues.
In the event of an open circuit, the driver goes into hiccup mode, where it will remain as long as the fault continues.
If it is connected at a load lower than that permitted in the operating area, the driver will supply a current of 70mA as
long as this situation is maintained.
4.3. Thermal protection
The iLC CORE control gear benets from thermal protection so that the power supplied is reduced when a temperature
excess is detected.
If, under normal operating conditions, the temperature at tc exceeds its maximum permitted value by 6ºC, the driver
will reduce the power supplied by up to 75% of the total.
If, during power reduction mode, the temperature at tc continues to rise until it exceeds its maximum permitted value
by 8ºC, the driver will reduce the load by up to 10% of the total.
While in either of the 2 power reduction modes, if the temperature at tc drops 6ºC 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:

4.4. Out-of-range mains voltage protection
The iLC CORE control gear is designed to withstand temporary fluctuations in mains voltage that are outside the
permitted range.
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
The iLC CORE drivers 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.
