Switch mode power supplies CP-E series The CP-E range of DIN Rail PSUs from ABB offer enhanced functionality. The switch mode power supply units are economic and can be operated at an ambient temperature of up to 70°C. With adjustable output voltages, they can also be adapted to the application required. This range offers output voltages from 5 V dc to 48 V dc at output currents of 06.25 A to 20 A. Thermal efficiency of up to 90% means that there is low power and heat dissipation allowing operation of the PSU without any forced cooling. The switch mode power supply can be snapped onto a DIN Rail according to IEC/EN 60715, and be mounted horizontally.

Furthermore it is equipped with two generous capacitors, which ensure mains buffering of at least 30 ms (at 230 V ac). These power supplies can be used worldwide also in high fluctuating networks and battery powered plants. Approvals UL 508, UL 60950, GOST, CCC, CE
