- Monitored Voltage: 240VAC
- Output: 10A SPDT
Product Substitution
The following product stocked at a distributor can be substituted for the VMP240A:
VAKP240A has adjustable drop-out voltage setting & adjustable time delay on drop-out of 0.1-10 seconds; the VMP240A has a fixed drop-out setting of 95% of pick-up setting & fixed time delay on drop-out of 500ms
Description Of Function
The relay energizes (and the LED is Red) when the monitored voltage is above the pick-up setting for a period longer than the fixed pick-up time delay of 0.5 seconds. The relay de-energizes (and the LED is Green) when the monitored voltage is below the drop-out setting for a period longer than the fixed drop-out time delay (t) of 0.5 seconds.
