PS-10A phase switch

PS-10A phase switch

ThePS-10A Phase Switch is designed to supply 220/230V 50Hz industrial and domestic single-phase consumers with power from one of the phases of a three-phase network to ensure that the most critical single-phase equipment is powered from the highest quality phase and protected against overvoltage or undervoltage.

The device is controlled by a microcontroller that analyzes the voltage in the three-phase network and displays the actual values on digital indicators for each phase. The output is switched to the load by electromagnetic relays. The device is powered by the monitored phases.

Programmable settings:

- Permissible limits for voltage switching/disconnection

- Priority phase

- Load switching delay time

- Switching delay time for lower limit
