Specification of

The DUV-R monitors under voltage of balanced 3-phase 3-wire mains. It has an adjustable setting of 110VAC – 115V to 88V 200VAC-210V to 160V 380VAC-399V to 304V 415VAC – 436V to 332V 480VAC-504V to 384V The relay trips if the voltage of the monitored mains drops below the preset point. If the mains voltages are unbalanced it will take the sum of the three individual phase voltages as reference. The DUV-R trips instantly.It has one tripping change-over contacts 11-14-12. Contacts 11-14 close for normal conditions and open for under voltage or no supply conditions.

 

The DUV-D monitors under voltage of balanced 3-phase 3-wire mains.

It has only one set of tripping change-over contacts 11-14-12. Contacts 11-14 close for normal conditions and open for under voltage or no supply conditions.

The DUV-2R monitors under voltage of balanced 3-phase 3-wire mains. It has an adjustable setting of 110VAC – 115V to 88V 200VAC-210V to 160V 380VAC-399V to 304V 415VAC – 436V to 332V 480VAC-504V to 384V The relay trips if the voltage of the monitored mains drops below the preset point. The DUV-2R trips instantly. It has two change-over contacts tripping 11-14-12 and 21-24-22. Contacts 11-14 and 21-24 close for normal conditions and open for under voltage or no supply conditions.

The DUV-2D monitors under voltage of balanced 3-phase 3-wire mains. It has an adjustable setting of 110VAC – 115V to 88V 200VAC-210V to 160V 380VAC-399V to 304V 415VAC – 436V to 332V 440VAC – 462V to 352V 480VAC-504V to 384V The relay trips if the voltage of the monitored mains drops below the preset point. If the mains voltages are unbalanced it will take the sum of the three individual phase voltages as reference. The DUV-2D has an adjustable tripping delay from 0 to 10 sec. It has two change-over contacts tripping 11-14-12 and 21-24-22. Contacts 11-14 and 21-24 close for normal conditions and open for under voltage or no supply conditions.

The DOV-R monitors over-voltage of balanced 3-phase 3-wire mains. It has an adjustable settings 110VAC-105V to 132V 200VAC-190V to 240V 380VAC – 361V to 456V 415VAC – 394V to 498V 480VAC-456V to 576V The relay trips if the voltage of the monitored mains risice above the preset point. If the mains voltages are unbalanced it will take the sum of the three individual phase voltages as reference. The DOV-R trips instantly. Contacts 11-14 close for normal conditions and open for over voltage or no supply conditions.

The DUOV-R monitors under and over-voltage of balanced 3-phase 3-wire mains. The relay trips if the voltage of the monitored mains drops below or rises above the respective preset points. If the mains voltages are unbalanced It will take the sum of the three individual phase voltages as reference. There are 2 separate sets of contacts; one for under voltage (11-14-12) and one for the over voltage (21-24-22) trip controls. There are also 2 amber LEDs to indicate the normal condition. For under or over voltage trip condition, the the corresponding LED willgo off and the corresponding relay will de-energize.
