Absopulse Electronics' PFC 619F-EH AC/DC plug-in switching power supply module generates an output power of 1500W depending on the specific input and output configuration. The power supply module employs a power factor corrected input and a following half-bridge stage to convert the universal AC input voltage to 24V DC or 40A or a 48V DC or 30A output with fan cooling. All heat-generating components on the module are installed on aluminum heat sink blocks, which are connected to the heat sink fins on the side of the module.
The plug-in power supply has an inbuilt 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 304mm and is used in 19inch rack-mount applications. The front panel of the module has an LED indicator, voltage adjustment potentiometer and test points.
The power factor is corrected to a minimum of 0.97 at full load and is compliant with the EN6100-3-2 directive for low input harmonic distortion. The unit has input and output filtering to meet EN55022 EMI standards. The electronic protection on the input and output eliminates the possibility of failure due to abnormal operating conditions, including application errors.
