Product Data Sheet 750 WATT AC/DC POWER SUPPLY KX750 DESCRIPTION The KX750 is a low profile, 750 watt, power factor corrected, triple output power supply utilizing a half-bridge topology operating at 250kHz. The compact design yields a power density in excess of 6 watts per cubic inch. Universal input and power factor correction to EN61000-3-2 make the KX750 an excellent choice for product applications with woldwide markets. In addition, the KX750 carries UL, CSA and TUV approvals, and complies with FCC and VDE Class B EMI requirements. Optional active current sharing on all three outputs simplifies N+1 redundant applicaitons. Remote sensing capability is standard on all outputs and will compensate for up to 0.7V line drop. All outputs are fully isolated, regulated, and current limited FEATURES � Active Power Factor Correction to EN61000-3-2 � 3.3V Main Output � FCC/VDE Class B EMI Filter � Active Current Sharing Optional � Fully Isolated and Regulated Outputs � Compact Size: 12” x 5” x 2” � 75% Efficiency Typical AGENCY APPROVALS � > 6 Watts Per Cubic Inch � Optional Fan Mounted On Cover � Optional Current Sharing On All Outputs Internet: http://www.cdpowerelectronics.com Power Electronics Division, United States Power Electronics Division, Europe C&D Technologies (Power Electronics) Ltd. 3400 E Britannia Drive, Tucson, Arizona 85706 Phone: 800.547.2537 Fax: 520.770.9369 132 Shannon Industrial Estate, Shannon, Co.
