Ault Korea / Power General FLU2-40-6 Dual Output Power Supply

The Ault Korea FLU2-40-6 is a 40 W open-frame switching power supply delivering dual independent outputs across a wide input range. Built on a flyback converter topology with fixed 40 kHz operation, it accepts universal AC input of 85–265 VAC at 47–440 Hz or 100–370 VDC, making it suitable for global deployment and battery-backed systems. The unit achieves an MTBF exceeding 200,000 hours and maintains output ripple and noise below 1% peak-to-peak maximum.
