KX750-F3A

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 > 6 Watts Per Cubic Inch Optional Fan Mounted On Cover Optional Current Sharing On All Outputs AGENCY APPROVALS Internet: http://www.cdpowerelectronics.com Power Electronics Division, United States 3400 E Britannia Drive, Tucson, Arizona 85706 Phone: 800.547.2537 Fax: 520.770.9369 KX750 4/99 REV B Power Electronics Division, Europe C&D Technologies (Power Electronics) Ltd. 132 Shannon Industrial Estate, Shannon, Co.

Remote Sense leads are protected against open, short, and reversal. Remote On/Off The power supply is turned on with a TTL logic ‘1’ (or open) signal and turned off by a switch closure or TTL logic ‘0’ referenced to (-) sense terminal. Consult the factory for other options. Over Voltage Protection Output #1: 6.25V, ±0.8 VDC. The power supply will latch off until AC power is cycled. Over Current Protection Individual current limit on all outputs. Automatic recovery upon fault removal. Reverse Voltage Protection All outputs are protected to rated load. Transient Response The peak output voltage excursion on the main output will not exceed 2% and will recover within 1% in 200 µSec for a 25% load step change. Output Isolation All outputs are fully isolated. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 5msec before loss of DC output. Upon AC input turn-on, signal remains low until outputs are in regulation referenced to (-) sense terminal. Consult the factory for other options. DC Power Good Signal Upon a ±10% loss of regulation on any output, the DC Good signal drops to a logic zero referenced to (-) sense terminal. Consult the factory for other options. Over Temperature Protection Internal thermal switch turns off power supply if overheating occurs and automatically restarts when temperature drops below threshold.
