PS1011-2420-0000 Installation Manual
Product Description
The PS1011-2420-0000 is a DIN-rail mountable single-phase-input power supply, which provides a
floating, stabilized and galvanically separated SELV/PELV/ES1 output voltage.
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, measurement, Audio/Video, information or
communication 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.
Without additional measures to reduce the conducted emissions on the output (e.g. by using a filter),
the device is not suited to supply a local DC power network in industrial, residential, commercial and
light-industrial environments.
Installation Instructions
Install 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 +55°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. Use ferrules for wires on the input terminals.
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 device is designed for overvoltage category II zones. Below 2000m altitude the device is tested
for impulse withstand voltages up to 4kV, which corresponds to OVC 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) 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.
