MACROMATIC INDUSTRIAL CONTROLS VWKE120A VOLTAGE MONITOR RELAY120VAC 15A SPDT

120V Voltage Relay. As long as the monitored voltage (Un) remains within the OVER (Umax) and 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. Provides voltage band (window) protection. Wide range of user-adjustable Over Voltage and Under Voltage settings. 15A SPDT output contacts. Adjustable time delay on drop-out of 0.1 - 10 seconds. LEDs indicate nominal voltage and output relay status.
