VP-20A voltage relay
Voltage relay VP-20A is designed to protect electrical devices and household appliances from unacceptable voltage fluctuations. The device continuously analyzes the mains voltage and, if it is exceeded, the connected devices are switched off, and the load is switched on automatically after the voltage returns to the preset range. The user sets the required upper and lower voltage limits and the time of the switch-on delay.
The switch-on delay is required for electrical appliances that do not tolerate short power outages (refrigerators, air conditioners, etc.).
Programmable settings:
- Value of lower and upper voltage tripping limit
- Load switch-on delay time
All preset values are stored in non-volatile memory.
Manufactured in Ukraine.
