LT-84A is equipped with a relay that can be used to turn ON/OFF LED driver. The relay is in the closed position when the CH1 generates dimming signal, the relay is in the open position
when there is no output signal on the CH1.
The maximum load of built-in relay: 8A resistive current load or less than 50A inrush current load. The breakdowns caused by overloading is not covered by the warranty.
