Megger CSU20A Current and Voltage Source

Includes: Megger CSU 20A user manual, cables and transport case 230 V Mains voltage.

Reference BF-42390

Brand Megger

The instrument featured on this page is the 230V model. If you require the 115V version please state at time of order.

The Megger CSU20A is a small light-weight current and voltage source primarily intended to work together with the SVERKER 750 Relay Testing Unit when testing differential relays. Besides testing differential relays the unit can be used as a multi-purpose AC/DC source.

Besides testing differential relays the unit can be used as a multi-purpose AC/DC source. The CSU20A features one AC current/voltage output, one fully rectified DC output and one half-wave rectified DC output for harmonic restraint testing.

Other features are a current measurement shunt, selectable current/voltage ranges and an AC mains input/output. Connecting the SVERKER 750/760 mains to the mains output of the CSU20A gives an in-phase synchronization of the two units.
