UV Electronic Power Supply is the newest high efficiency and intelligent UV variable-frequency power supply in the UV curing industry. It can replace traditional UV transformer and capacitor. It can save more than 30% of energy by dynamic stepless regulation. It adopts 32-bit high performance TIDSP microprocessor. Based on the advanced feedforward and PID power control algorithm, it achieves high dynamic response. With constant power output and 10-100% free adjustment, one single equipment can meet the different needs of UV mercury lamp, Gallium lamp and Iron lamp (metal halide lamp). It includes RS485 communication encoder interface, multiple digital input and output interface. It can flexibly realize multi units network or PLC touch screen control.
