VWKP240A产品概述
Macromatic’s VWKP Series Voltage Band Voltage Monitor Relays provide protection to equipment that is required to operate within an upper and lower voltage limit. As long as the operating voltage remains within an Over and Under Voltage range, the internal relay stays energized. If the operating voltage falls outside this range, the relay will drop-out.

Specifications:
Monitored Voltage: 240V AC
Output: 10A DPDT
Temperature: –28°C to 65°C

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 drop-out time delay (t), which is adjustable between 0.1-10 seconds.
