Schaefer unveils DC/DC and AC/DC converter modules

The C5100 Series is available in three standard DC input voltage ranges from 320-800V DC, as well as 3 x AC input voltages of 3 x 400V AC (320-460) and 3 x 480V AC (400-530).

Single outputs are available in six standard ranges from 23-200V DC.

All outputs are adjustable and fully regulated to 0.2 per cent or better (load) and 0.1 per cent (line).

All modules in the C5100 Series have remote sensing (up to 150V output), overvoltage protection, and current limit protection on the output.

Efficiencies are up to 95 per cent.

Operating temperatures available include -20C to +75C and - 40C to +75C.

The units are packaged in a 3U x 40TE x 538mm rack module for space saving, and incorporate Combitec I/O connectors.

They can be rotated for 5U mounting.

Options include decoupling diodes for parallel/redundant operation, 'ruggedisation', inhibit, Power Fail/DC-OK alarms, system reset, active current sharing, and programming.

Applications include railway controls and communications equipment (onboard and trackside), military, transportation, telecommunication systems, process control systems and power stations.

Mechanical and electrical modifications to standard modules are available.

In addition, Schaefer can design and manufacture fully custom systems.
