Phase voltage controller

Monitoring of asymmetry, phase sequence and phase loss of 3-phase 3-wire or 4-wire power supplies for all models. Multi-voltage models allowing stock reduction (switchable) Phase sequence, phase loss: operating delay of 0.1 s maximum Asymmetry: operating delay of 0.1 to 30 s Reset method: automatic Power-on delay: 1 s or 5 s
