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.
The device is suitable to be supplied from TN, TT or IT mains networks. The continuous voltage between the
input terminals and the PE potential must not exceed 300Vac.
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). Above 2000m (6560ft) the overvoltage category is
reduced to level II and a reduction in output current is required.
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 20A without additional protection device.
For higher branch circuits use an additional protection device. If an external input protection device is utilized, do
not use one smaller than a 10A B- or 6A C-characteristic to avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the same as the
ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any kind of loads,
including inductive and capacitive loads. If capacitors with a capacitance >3F are connected, the unit might
charge the capacitor in an intermittent mode.
Do not apply return voltages from the load to the output terminals higher than 35V.
The output voltage can be adjusted with a small flat-blade screwdriver on the front of the unit.
The green DC-OK LED reports an output voltage above 18V of a running device.
The DC-OK relay monitors the output voltage of a running device. The contact is closed when the output voltage
is above 22V. Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The device is equipped with an over-temperature protection. In case of a high temperature, the output shuts down
and starts automatically again after cooling off.
At heavy overloads (when output voltage falls below 13V), the device delivers continuous output current for 2-5s.
After this, the output is switched off for 7s before a new start attempt with 1s is automatically performed. This
cycle is repeated as long as the overload exists.
Do not parallel devices for higher output currents.
Same devices can be connected in series for higher output voltages. It is allowed to connect as many devices in
series as needed, providing the sum of the output voltage does not exceed 150Vdc.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 32V. The output shuts
down and automatically attempts to restart.
