The Macromatic VWKP480A is a voltage monitor relay. This 8 Pin plug-in relay has a nominal voltage of 480V AC and an output of 10A SPDT. This voltage band relay is used for equipment that has to work within a certain voltage range. The VWKP480A features adjustable over and under voltage presets, as well as an adjustable drop out time delay ranging from 0.1-10 sec. The VWKP480A has an LED that is red to indicate when the unit is energized or green when it is not. It uses an 8 Pin 70169-D octal socket.

When the voltage stays between the preset over and under voltage settings, the unit stays energized. If the voltage goes over or under the preset range for a greater duration than the drop-out time delay, it de-energizes. Once the voltage goes back within the safety range for a longer duration than the 0.5 sec pick up delay, the relay is energized again.
