CP10.241-R2, CP10.241-R2-C1 Installation Manual
EN
Product Description
The CP10.241-R2 is a DIN-rail mountable single-phase-input power supply with a built-in decoupling
MOSFET for 1+1 or n+1 redundant power supply systems. It provides a floating, stabilized and
galvanically separated SELV/PELV output voltage. Plug connectors allow a replacement on a running
application.
The CP10.241-R2-C1 device is the same as the CP10.241-R2 but with conformal coated pc-boards.
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.
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. Other mounting orientations require a reduction in output current.
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.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or
frost allowed.
The enclosure of the device provides a degree of protection of IP20.
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- and IT mains networks. The voltage between the L
or N terminal and the PE terminal must not exceed 300Vac continuously.
The input can also be powered from batteries or similar DC sources. The voltage between the input
terminal and the PE terminal must not exceed 375Vdc continuously.
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 6000m (19685ft). See additional requirements in the product
datasheet for use above 2000m (6560ft).
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 32A (IEC) and 30A (UL) without
additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than 6A
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 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Do not unplug the connectors more often than 20 times in total.
Functional Description
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. If capacitors with a capacitance
>1.5F 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 green DC-OK LED reports an output voltage above 22Vdc of a running device.
The DC-OK relay monitors the output voltage and the contact is closed when the DC-OK LED is on.
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 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. The ambient temperature is not allowed to
exceed +70°C. Above +37°C, the sum of output current must be reduced. The device is featured with
a "soft output regulation characteristic" in order to achieve current share between multiple devices,
when they are connected in parallel. The "soft output regulation characteristic" 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.
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.
