The PFC 619F-EH ac/dc plug-in switching power supply module generates up to 1,500-W output power, depending on the input/output configuration. It employs a power-factor-corrected input and a following half-bridge stage, to convert the universal ac input voltage to 24 Vdc/40 A (1,000 W) or a 48-Vdc/30-A (1,500-W) output with fan cooling. All heat-generating components on the module are installed on aluminum heat-sink blocks.
The plug-in power supply has a built-in redundancy diode for parallel connection or n + 1 redundant operation. It includes a module fail alarm with an optocoupler output. The module measures 6U x 16HP x 304 mm and is typically used in 19-in. rack-mount applications. The front panel of the module has an output voltage ‘on’ LED indicator, voltage adjustment potentiometer and test points. ($860 ea/small qty – available now.)
