Voltage Monitoring Relay

Minilec has recently launched many new products with excellent additional user-friendly features. Voltage monitoring relay D2 VCT1 combines VCT D2 and BVCF D2 in one unit with all their existing features and also additional extra features. Distinctive features: The relay is micro-controller based, hence more reliable and accurate. Trip time delay and power On delay is site selectable with improved dial markings. Under and over voltage trip settings are absolute values of voltage and not in percentage as was in earlier models. This is more convenient for user to know the settings. It is suitable for any system supply voltage between 380 V to 440 V. Under voltage lowest value is -25% of 380 V, and over voltage highest value is +20% of 440 V. Hence, for normal supply of 415 V, this will be more than ±25% as against ±20% as in case of earlier models. Hence, there is a wide voltage band available for selection. There is separate indication for Neutral Fail. Additionally the relay has: (a) Auto reset and manual reset selection, (b) Failsafe and non-failsafe selection, as well as (c) Either common relays or separate relays selection for under D1 VCR1 is under and over voltage relay equivalent of VCRD2 but in D1 box. This is a very compact model for monitoring single phase supply voltages. Under/over voltage trip setting range from -25% to +20%, and 2 CO output contacts are major features of the relay.
