EN
Product Description
The PS2001-2420-1001 is a DIN rail mountable single-phase-input power supply that provides a
floating, stabilized and galvanically separated SELV/PELV output voltage.
The device provides access to operation data and device settings via a built-in EtherCAT interface
(also refer to datasheet for details)
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like. Do not use this
device in equipment where malfunction may cause severe personal injury or threaten human life.
If this device is used in a manner outside of its specification, the protection provided by the device may
be impaired.
Installation Instructions
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of the
device.
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. Use ferrules for wires
on the input terminals. 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 housing 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 terminals and the PE potential must not exceed 300Vac.
The input can also be powered from a battery or a similar DC source. The continuous voltage between
the supply voltage and the PE/ground potential must not exceed 375Vdc.
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. Above 2000m a reduction in output current and over
voltage category is required.
Keep the following minimum installation clearances:

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 10A
B- or C-Characteristic to avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C. 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 unlimited inductive and capacitive loads. If capacitors with a capacitance >1F
are connected, the unit might charge the capacitor in an intermittent mode.
Do not apply return voltages from the load to the output 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 above 22V of a running device.
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 2s. After this, the output is switched off for 18s before a new start attempt is automatically
performed. This cycle is repeated as long as the overload exists.
Devices can be paralleled to increase the output power but only if ambient temperature does not to
exceed +60°C. The output voltage of all devices shall be adjusted to the same value (±100mV) in
"Single Use" mode with the same load conditions on all units, or the units can be left with the factory
settings. After the adjustments, set the unit to "Parallel Use" mode, in order to achieve load sharing.
The "Parallel Use" mode regulates the output voltage in such a manner that the voltage at no load is
approx. 4% higher than at nominal load. Energize all units at the same time. It also might be
necessary to cycle the input power (turn-off for at least five seconds), if the output was in overload or
short circuit. If more than three devices are connected in parallel, a diode, fuse or circuit breaker with a
rating of 30A or 32A is required on each output.
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
switches off and performs three restart attempts. If the failure continues, the output shuts down. Cycle
input power to reset.
See EtherCAT user manual (and/or datasheet) for information how to connect the device to EtherCAT
networks.
