Note: this is an optional accessory for Megger SVERKER750 and SVERKER780 relay testing units.
Use the CSU20A alongside a Megger SVERKER750 or SVERKER780 relay tester to generate two independent current sources, allowing you to use the SVERKER's timer/measurement section to measure two outputs, plus the trip time of a relay.
The CSU20A is also suitable for use as a multifunctional AC/DC voltage source. It has one AC current and voltage output, one fully rectified DC output and one half-wave rectified DC output for performing harmonic restraint testing.
Additional features of the Megger CSU20A include a current measurement shunt, selectable voltage and current ranges and AC mains input/output. When connected to the SVERKER's mains output, the CSU20A gives an in-phase synchronisation of the two units.
