Product Description
The CP20.241 is a DIN-rail mountable single-phase-input power supply of the DIMENSION series. It
provides a floating, stabilized and galvanically separated SELV/PELV output voltage.
The CP20.241-C1 device is the same as the CP20.241 but with conformal coated pc-boards.
Intended Use
This device is designed for installation in an enclosure and is intended for general use such as in
industrial control, office, communication, and instrumentation equipment. Do not use this device in
equipment, where malfunction may cause severe personal injury or threaten human life.
Installation Notes
- 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 the device to the factory for inspection.
- 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. For other orientations see de-rating requirements in the datasheet.
- 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.
- For use in a controlled environment. Do not use the device in pollution degree 3 areas without
additional protection or in applications where a degree of protection better than IP20 is required.
- 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 acc. to IEC 62477-1.
- The device is designed for overvoltage category III acc. to IEC 62477-1 and II acc. to IEC 60950-1.
- The input can also be powered from batteries or similar DC sources. The voltage between the (+)
or (-) input terminal and the PE terminal must not exceed 375Vdc continuously acc. to IEC 62477-1.
- A disconnecting means shall be provided for the input or output of the device when used in
applications according to CSA C22.2 No 107.1-01 or CSA C22.2 No 107.1-16.
- The device is designed as “Class of Protection I” equipment according to IEC 61140. A PE
(Protective Earth) connection is required.
- The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including unlimited inductive loads and capacitive loads up to 1F.
- Do not apply return voltages from the load to the output higher than 35V.
- The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid (e.g. cable conduits) by more than 15%!
- The device is designed for altitudes up to 6000m. See details in the product datasheet for additional
requirements above 2000m.
- Keep the following minimum installation clearances when the device is permanently loaded with
more than 50% of the nominal current: 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.
- 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 / +158°F. The operational temperature is the
same as the ambient or surrounding air temperature and is defined as the air temperature 2cm
below the device.
- For suitable accessories, such as mounting brackets or supplementary devices, see product datasheet.
Functional Description
- The output voltage can be adjusted. Open the flap on the front to set the output voltage with a small flat-
blade screwdriver. The factory setting is 24.1V.
- The green DC-OK LED on the front of the device reports a functional unit and is synchronized with the
DC-OK relay contact. The LED is on when the output voltage is >90% of the adjusted output voltage.
- The DC-OK relay contact monitors the output voltage, which is produced by the device itself. It is
independent of a back-fed voltage from a device connected in parallel to the device’s output.
- The device is equipped with an over-temperature protection. In case of a high temperature, the
output shut-down and starts automatically again after cooling off.
- The device is equipped with the Hiccup
PLUS
overload characteristic. 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 approx. 18s 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.
- Devices can be paralleled to increase the output power. 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. If more than
three devices are connected in parallel, a fuse or circuit breaker with a rating of 30A or 32A is
required on each output. Alternatively, a diode or redundancy module can also be utilized.
- Devices of the same type can be connected in series for higher output voltages. It is possible to
connect as many devices in series as needed, providing the sum of the output voltage does not
exceed 150Vdc. Avoid return voltages from the load to the output.
- 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.
