Description
 

The Macromatic VAKP240A is a voltage monitor relay. This 8 Pin plug-in relay has a nominal voltage of 240V. It monitors against over or under voltage errors and has an output of 10A SPDT. The VAKP240A features an adjustable pick-up voltage, adjustable drop-out voltage, and an adjustable time delay ranging from 0.1-10 sec. It features an LED that is red when the unit is energized or green when it is not. It uses an 8 Pin 70169-D octal socket. Whether the relay operates for undervoltage or overvoltage protection is subject to the kind of output contacts being used.

Macromatic VAKP Series Relay Installation Instructions

Additional Product Information

When the voltage stays above the preset pick-up voltage (180-300V AC), then the unit is energized. If the voltage goes below the preset drop out (135-285V AC), for greater duration than the drop-out time delay, then it de-energizes.

Overvoltage
Overvoltage protection makes use of a normally closed contact. The voltage needs to stay below the preset pick-up voltage for the load to be energized while the relay itself remains de-energized. If the voltage goes above the pick-up, the reverse happens, until voltage goes below the preset drop-out.

Undervoltage
Undervoltage monitoring requires a normally open contact. The load stays on and the relay is energized if the voltage stays above the preset pick-up. Voltage going below the preset drop-out de-energizes both the load and the relay.
