I am powering the sensor relays using the same 240Vac Power Source that is lighting up the Metal Halide Lights. I was just made to understand that the power source for these Lights are connected via the EMU which is the energy saving equipment. The EMU will effectively reduce the power by 30%. The reduction is done by dropping the Voltage from 240Vac to about 168Vac. As we know the relays are rated at 240Vac. Will this reduction in voltage during the energy saving mode affect the performance of the Sensor Relays?
