1. The VP-002 is a range of phase failure/ phase sequence/ under voltage/overvoltage protection relays to continuously monitor AC power supplies both single phase, and three phase.
2. Output relay will operate to ON (pin 1& pin 3 close) when power is applied to the unit normally, and simultaneously detect if supplied power voltages (single or three phase) are within the set voltage range, and phase in correct sequence for three phase type.
3. 0% to 20% Knob-adjustable separately for over voltage and under voltage. If voltage is over or under than the setting voltage for over 3 second, then the output relay will be released to its original position (pin 1& pin 4 close).
1. Rated voltage: AC 110V, 220V, 230V, 380V, 415V, 440V. 2. Frequency: 50 or 60 Hz. 3. Response time of relay: delay on: 0.5 sec., delay off: 3 sec. 4. Contact rating: 250V AC 5A (P.F.=1). 5. Mounting and socket: surface: PF-113AE. 6. Reset time: 0.2 sec Max.
