Description

This is a compact micro-electronic device based on latest technology. It senses the voltage supply at its terminals and operates electromagnetic relay in case of over voltage condition. Thie relay gets energised/ON for over voltage condition in any of phases. Over voltage setting and On/Off Time delays are continuously adjustable with the help of a knob over linear caliberated dial. Separate terminals for Auxillary voltage / operating voltage are provided in case of 3 three phase models. Two change over contacts are provided for customer's usage. Three LED's (Light Emitting Diodes) are provided on top of the unit to indicate 'Voltage Supply On', Relay ON' and Over Voltage Condition'.

Three Phase Without Neutral-3p
Over Voltage Setting : 400-500 VAC (Backlash -7 VAC)
Auxillary / Operating Supply : 415 VAC
ON/OFF Time Delay : 1-15 Seconds

This is a compact micro-electronic device based on latest technology. It has two electromagnetic relays for the purpose of output contacts. One relay is for giving starting attempts with adjustable On and OFF timings with the help of two separate knobs over linear calibrated dial. The second relay is for giving a fail to start indication / alarm, when factory set number of attempts (normally three) are completed. The fail to start relay energies with a time delay, equal to helf of the off time delay setting after the set number of attempts are completed. N.O. (normally open) potential free contact of both the relays are provided for customer''s usage.
Number of starting attempts are set for 3 as standard but can be provided anywhere form 1 to 15. This is only factory set and therefore has to be specified at the time of order.
Setting/ Repeat Accuracy± 2% of the set time.

Operating Voltage

12 VDC or 24 VDC or any other voltage including A.C. on special requirement (+25% to -35% of supply voltage variation is acceptable)
Relay Contact Rating

6Amps resistive load or 2 Amps inductive load at 230 VAC or 24 VDC.
Insulation

The unit will withstand 2.5% KV 50Hz for one minute between all external A.C. supply and relay contact terminals connected together and body.
