output overvoltage protection (30.5Vdc typ. / 32Vdc max.)
Overload / short-circuit current -- 9.8A max. (R.M.S.) current / (typ. 70A) intermitted current peak for typ. 12ms at load impedance 10mΩ
Series / parallel operation -- devices of the same type can be connected in series for higher output voltages / Power supplies can be paralleled to increase the output power. For redundancy applications 1 extra power supply is always needed for sufficient output current in case 1 unit fails.
Back-feeding loads max. 35V -- 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. First of all high immunity to transients and power surges as well as low electromagnetic emission and Marine approvals with EMC Class B make the CP20.245-R2 the best choice for equipment in bridge & deck zones the same way as for oil gas and chemical plants. This power supply furthermore features a DC-OK signal contact to remotely monitor error-free operation a decoupling MOSFET to set-up redundant power supply systems and plug connector terminals to allow device replacement while the application keeps running. The CP20.245-R2 covers an extreme wide temperature range from -40°C up to +60°C providing full output power. Outstanding features of CP20.245-R2 are its high efficiency the electronic inrush current limitation and an active PFC. The power supply has a power reserve of 20% included which may even be used continuously at temperatures up to +45°C. Additionally the device can deliver about 3 times the nominal output current for 12ms which helps to trip fuses on faulty output branches.
