VWKE Series Voltage Relays

VWKE240A

Lead Time: In Stock

$102.56 (USD) / EACH

Description Of Function

As long as the monitored voltage (Un) remains within the OVER (Umax) & UNDER (Umin) voltage settings, the internal relay stays energized. If the monitored voltage falls outside this range, the relay will drop-out. The Umax dial sets the upper limit per the Overvoltage range of the product. The Umin dial sets the lower limit at 30-95% of the upper setting. This product has an adjustable time delay on drop-out of 0.1-10 seconds (t) to prevent nuisance tripping.

Operation

Bar graph with wavy lines

Provides protection to equipment that is required to operate within an upper & lower AC single phase or DC voltage limit. As long as the monitored voltage (Un) remains between the OVER (Umax) & UNDER (Umin) voltage settings, the internal relay stays energized. If the monitored voltage falls outside this range, the relay will drop-out. The Umax dial sets the upper trip setting per the Overvoltage range of the product. The Umin dial sets the lower trip setting at 30-95% of the upper setting. These products have an adjustable time delay on drop-out of 0.1-10 seconds (t) to prevent nuisance tripping. They have a compact 17.5mm enclosure which snaps on to 35mm DIN track. This conserves space & reduces installation time, which saves money.
