Application

Automatically prevent overloading of a backup generator.

Scenario

A facility, equipped with a backup generator, has some power-hungry equipment, which the generator is incapable of running. They want to automatically disconnect the power-hungry equipment from the supply circuit whenever the generator comes on-line, thereby preventing the generator from overloading.

Solution

ILLUMRA SLT power sensors can be used to detect the presence of a supply voltage, and transmit a control signal to a corresponding relay receiver. The SLT power sensor was connected to the AC output of the generator. In this case, the relay receiver drove the coil of a much larger contactor, which is capable of switching the power-hungry equipment. The ILLUMRA components were installed quickly and help the facility to run more smoothly.
