Three Phase Voltage and Current Amplifier
CMS 156 Three Phase Voltage and Current Amplifier
The three-phase voltage and current amplifier CMS 156 serves as an additional device to the CMC test set, for tests requiring:
- higher current and/or voltage
- higher power in the voltage and/or the current path
- up to 9 (with CMC 256plus/CMC 356) independent current phases (e.g. for testing differential relays) or
- 6 independent voltage phases (e.g. for testing synchronizing devices with 6 independent voltages).
- in single-phase applications
