screw-clamp connections

output overvoltage protection (58.5Vdc typ. / 60Vdc max.)
Overload / short-circuit current -- 4.7A max. (R.M.S.) current / (typ. 15A) intermitted current peak for typ. 2s at load impedance 10mΩ
Series / parallel operation -- devices of the same type can be connected in series for higher output voltages / Devices can be paralleled to increase the output power. The output voltage shall be adjusted to the same value (+/-100mV) with the same load conditions on all devices (or the devices can be left with the factory settings). Devices can be paralleled for 1+1 redundancy to gain higher system availability using a redundancy module
Back-feeding loads max. 63V -- The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. The absorbing energy can be calculated according to the built-in large sized output capacitor.

The Dimension CP-Series are cost optimized power supplies without compromising quality reliability and performance. The CP-Series is part of the DIMENSION power supply family. The most outstanding features of CP20.481 are the high efficiency electronic inrush current limitation active PFC wide operational temperature range. The small size is achieved by a synchronous rectification LLC technology and by many further technological design details. The C-Series includes all the essential basic functions The device has a power reserve of 20% included which may even be used continuously at temperatures up to +45°C. Additionally the CP20.481 can deliver about 3 times the nominal output current for 12ms which helps to trip fuses on faulty output branches. High immunity to transients and power surges as well as low electromagnetic emission a DC-OK relay contact and a large international approval package make this unit suitable for nearly every situation.
