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 enclosure does not provide protection
against spilled liquids.
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 terminal 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, 0mm left and right side.
Increase the 0mm to 15mm in case the adjacent device is a heat source.
The device is designed, tested and approved for branch circuits up to 20A without additional protection device. If
an external fuse is utilized, do not use circuit breakers smaller than 6A B- or 4A 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. Capacitive loads should not be larger than 5500µF with 3.8A or 7000µF
with 1.9A additional current load.
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.
At heavy overloads (when output voltage falls below 14V), the device delivers continuous output current for 20ms.
After this, the output is switched off for 160ms before a new start attempt is automatically performed. This cycle is
repeated as long as the overload exists.
Do not parallel devices for higher output currents.
Do not connect outputs of devices in a series connection for higher output voltages.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 32V. The output shuts
down. To attempt a restart, turn the input power off for at least 90s.
