Universal Relay Test Set and Commissioning Tool

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high-power demands.

The six current and four voltage output channels are continuously and independently adjustable in amplitude, phase, and frequency.

All outputs are overload and short-circuit proof and are protected against external high-voltage transient signals and over-temperature.
