PH-104 Voltage Monitoring Relay
PH-104 Voltage Monitoring Relay ( “Volt Control”) is designed to protect home appliances (equipment) (refrigerators, air conditioners, washing machines, television, video and audio equipment, etc.) against the unacceptable voltage fluctuations and the effects of the neutral conductor interruption.
- provides the turn off of the protected equipment, if the voltage in the mains falls outside the range of the user-defined values (after network settings recovery the аuto-reclosing (hereafter AR) will occur);
- reduces the level of high frequency interferences;
- indicates the effective values of the input voltage, the condition of the accident and the condition of the output relay.
