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. Note: Image is an approximation. Actual part may differ.

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.
