1200W Front-End Supplies Support Current-Sharing And Hot-Swapping

The AFE1200 series power supplies are available with 48 or 24 Vdc outputs; the 48V model can deliver up to 25A and the 24V model can deliver up to 50A. Both models also provide an auxiliary 12V/1A dc output for powering items such as external housekeeping circuitry. The auxiliary output is isolated from the main output, and both outputs are fully floating, enabling users to adopt whatever rail reference configuration they require. The supplies have an 85 to 264 Vac universal input range and accommodate mains frequencies from 47 to 63 Hz, enabling them to operate from any standard single-phase mains supply virtually anywhere in the world. The supplies incorporate power factor correction, providing a minimum power factor of 0.99. They also comply with IEC1000-6, -3 and -2 for immunity to conducted and radiated emissions and electrostatic discharge, and meet CISPR 22 and FCC-CFR class A standards for conducted and radiated noise.
