PS-40A phase switch
- PS-40A phase switch
PS-40A phase switch
The PS-40A 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 in order to provide power to the most critical single-phase equipment from the highest quality phase and protect it from 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
- Switching delay time for the load
- Switching delay time for lower limit
- Delay time for return to priority phase
All set values are stored in non-volatile memory.
Manufactured in Ukraine.
