The Relay, Voltage Sensing, DPDT, 12VDC from Macromatic Controls is designed to monitor AC single phase and DC voltages, providing protection against over and under voltage conditions. It features user-adjustable pick-up voltage settings ranging from 85-115% of the nominal voltage, with a fixed drop-out voltage set at 95% of the pick-up setting. The relay includes an adjustable time delay on drop-out, which can be set between 0.5 to 10 seconds. This relay has a compact plug-in design that utilizes an industry-standard 8-pin octal socket and offers 10A DPDT output contacts. It operates effectively within a temperature range of -28¬8C to 55¬8C and has a mechanical life of 10 million operations, with a full load life of 100,000 operations. The relay is suitable for applications requiring voltage monitoring and control, making it a viable option for engineers needing reliable voltage sensing solutions.
Over/Under Voltage Relays provide protection to equipment where an over or under voltage condition is potentially damaging. They are designed to operate when the operating voltage reaches a preset value and drop-out when the operating voltage drops to a level below the preset value.
The pick-up voltage setting is user-adjustable from 85-115% of the nominal voltage rating. As standard, the VAP Series has a drop-out voltage setting fixed at 95% of the pick-up voltage setting. An adjustable drop-out setting of 75-95% of the pick-up setting is available on the VAKP Series. The relay energizes when the monitored voltage is above the pick-up setting. The relay de-energizes when the monitored voltage is below the drop-out setting for a period longer than the drop-out time delay (T), which is adjustable from 0.5-10 seconds for VA Series products. A version with a time delay on drop-out fixed at 500ms is available (see VM Series).
