Description
Voltage relay DigiTOP VP-20A G3WÂ 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 switch-on delay time.
Allowable shutdown limits, switch-on delay time, frequency control mode selection and digital display brightness level are set by the user using the buttons located on the front panel of the device. All set parameters are stored in non-volatile memory.
