Installation Instructions
4 Installation Instructions
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused
by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power
off and send unit to the factory for inspection.
Install the device in an enclosure providing protection against electrical, mechanical
and fire hazards.
Install the device onto a DIN mounting rail according to EN 60715 with the input terminals on
the bottom of the device. Other mounting orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate
copper cables that are designed for a minimum operating temperature of 60°C for ambient
temperatures up to +45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient
temperatures up to +70°C. Ensure that all strands of a stranded wire enter the terminal
connection. Unused screw terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments.
No condensation or frost is allowed.
The enclosure of the device provides a degree of protection of IP20.
The isolation of the device is designed to withstand impulse voltages of overvoltage category
III according to IEC 60664-1.
The device is designed as "Class of Protection I" equipment according to IEC 61140.
Do not use without a proper PE (Protective Earth) connection. Use the terminal on the input
block for earth connection and not one of the screws on the housing.
The device is suitable to be supplied from TN-, TT- and IT mains networks. The voltage
between the L or N terminal and the PE terminal must not exceed 300Vac continuously.
The input can also be powered from batteries or similar DC sources. The voltage between
the input terminal and the PE terminal must not exceed 360Vdc continuously.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan.
Do not obstruct airflow and do not cover ventilation grid!
The device is designed for altitudes up to 5000m (16400ft). See additional requirements
in this document for use above 2000m (6560ft).
Warning!
Explosion hazard from live wiring of non-intrinsically safe circuits
•Turn power off before working on the device. Protect against inadvertent re-powering.
•Do not modify or repair the unit.
•Do not open the unit as high voltages are present inside.
•Use caution to prevent any foreign objects from entering the housing.
•Do not use in wet locations or in areas where moisture or condensation can be expected.
•Do not touch during power-on, and immediately after power-off. Hot surfaces may cause
burns.
Note
If you use the device in hazardous areas, observe the safety information in the instruction
manual and in chapter 21.

Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom,
5mm left and right side. Increase the 5mm to 15mm in case the adjacent device is a heat
source. When the device is permanently loaded with less than 50%, the 5mm can be reduced
to zero.
The device is designed, tested and approved for branch circuits up to 32A (IEC) and 30A (UL)
without additional protection device. If an external fuse is utilized, do not use circuit breakers
smaller than 6A B- or C-Characteristic to avoid a nuisance tripping of the circuit breaker.

Output
8 Output
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input
voltage.
The output is designed to supply any kind of loads, including capacitive and inductive loads.
If extreme large capacitors, such as EDLCs (electric double layer capacitors or "UltraCaps")
with a capacitance > 0.3F are connected to the output, the unit might charge the capacitor
in an intermittent mode.
The output is electronically protected against overload, no-load and short-circuits.
In case of a protection event, audible noise may occur.
Output voltage Nom. 24V
Adjustment range Min. 24-28V Guaranteed value
Max. 30.0V This is the maximum output voltage which can
occur at the clockwise end position of
the potentiometer due to tolerances. It is not
a guaranteed value which can be achieved.
Factory settings Typ. 24.1V ±0.2%, at full load and cold unit
Line regulation Max. 10mV Between 85 and 300Vac
Load regulation Max. 50mV Between 0A and 6A, static value, see Figure 8.1
Ripple and noise voltage Max. 50mVpp Load >0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Max. 200mVpp Load <0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Output current Nom. 6A 1 At 24V and an ambient temperatures below 45°C
Nom. 5A At 24V and 60°C ambient temperature
Nom. 3.8A At 24V and 70°C ambient temperature
Nom. 5.1A 1At 28V and an ambient temperatures below 45°C
Nom. 4.3A At 28V and 60°C ambient temperature
Nom. 3.2A At 28V and 70°C ambient temperature
Derate linearely between +45°C and +70°
Fuse breaking current Typ. 15A Up to 12ms once every five seconds,
see Figure 8.2.
The fuse braking current is an enhanced transient
current which helps to trip fuses on faulty output
branches. The output voltage stays above 20V.
Overload behaviour Continuous current For output voltage above 13Vdc, see Figure 8.1
Intermittent current 2For output voltage below 13Vdc, see Figure 8.1
Overload/ short-circuit
current Max. 7.2A Continuous current, see Figure 8.1
Typ. 9A Intermitted current peak value for typ. 1s
Load impedance 50mOhm, see Figure 8.3
Discharge current of output capacitors is not included.
Max. 3.5A Intermitted current average value (R.M.S.)
Load impedance 50mOhm, see Figure 8.3
Output capacitance Typ. 2 000µF Included inside the power supply
Back-feeding loads Max. 35V The unit is resistant and does not show
malfunctioning when a load feeds back voltage
to the power supply. It does not matter whether
the power supply is on or off. The absorbing
energy can be calculated according to the built-in
large sized output capacitor.
1This current is also available for temperatures up to +70°C with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
2At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this,
the output is switched off for approx. 9s before a new start attempt is automatically performed. This cycle is repeated as long
as the overload exists. If the overload has been cleared, the device will operate normally. See Figure 8.3.

Hold-Up Time
9 Hold-Up Time
The hold-up time is the time during which a power supply’s output voltage remains
within specification following the loss of input power. The hold-up time is output load
dependent. At no load, the hold-up time can be up to several seconds. The green DC-OK lamp
is also on during this time.
