The TDK/Kepco RCW5-150K is a 750 W industrial-grade power supply delivering 5 VDC at up to 150 A for demanding automation, test, and high-power electronic applications. Built on proven RCW Series architecture, this single-output module combines active power factor correction, wide-range input capability (85–264 VAC or 110–370 VDC), and integrated EMI filtering to achieve FCC Class A compliance and EN61000-3-2 harmonic current certification. The unit operates across 50–60 Hz mains (extended operation to 440 Hz available) and tolerates 2 kV, 1 µsec surges between AC input and ground.
