ABB , the leading power and technology group has significantly enlarged its range of switch-mode power supply devices (SMPS). Supplementing the existing CP series for nominal currents of 0.3A up to 20A, there are now new CP-S and CP-C series for the range of 5 to 20A available.

With primary switch mode, the CP range offers a number of advantages in comparison to conventional power supplies. These include an integrated input fuse and open circuit, overload and short-circuit stability, plus automatic recovery.

All power supply units of the CP, CP-S and CP-C series are primary SMPS, which guarantee the best possible efficiency (>88%), minimized losses, environmental compatibility and cost efficiency.

The SMPS devices of the CP-C series are characterized by their modular, plug-in functional modules that extend the functionality of the devices, tailored to the requirements of the customer. The CP-C MM signal module for example, monitors the input and output voltage, and has a remote-OFF function.

The new CP-S and CP-C range possess power supplies, which are fully rated for operation at 60°C. They are also derated to 70°C operation and feature power reserves of up to 50% at 40°C. The 5A and 10A models have pluggable, double connection terminals plus LED indication - “output OK”. All of them are CE and C-Tick marked.
