The PPF 250-P59X series of fully encapsulated, industrial quality ac/dc power supplies deliver up to 250W output power from a universal (95V to 264Vac) range power factor corrected (PFC) input. The units deliver a single, regulated output of 12Vdc, 24Vdc, 48Vdc, 72Vdc, 110Vdc, 125Vdc or custom. A DC-input version, which offers a 95-350Vdc input range, is also available. Typical conversion efficiency is 80% at full load.

The power factor is corrected to a minimum of 0.97 at full load for the entire input range in compliance with EN6100-3-2 for low input harmonic distortion. The unit is filtered to meet EN55022 EMI Class A with generous margins. Full electronic protection on the input and output eliminates the possibility of failure due to abnormal operating conditions, including application errors.

The units are fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating and meet environmental criteria as requested in MIL-810C, D. This ensures protection from high levels of shock and vibration, moisture and other contaminants. Conduction and convection cooling enable operation over a -40°C to +70°C temperature range for full specification with no derating required.
