This power control box has a 9 foot long, 14 ga. cord. It has an on/off switch that controls a duplex, for dust collector, shaker, etc., and power to an LED driver which converts 120VAC to 24VDC. There are four 24VDC power jacks to supply the LED lights for RCV unit and othe cabinet lights. The electronics people tell us the LED driver is a powersupply that controls the voltage going to the LEDs. which will make them last longer.
