250W, Encapsulated AC-DC Power Supply with PFC-Input for Heavy Duty Applications

The PPF-250-P59XW series of encapsulated, industrial quality ac/dc power supplies deliver up to 250W output power. The units employ active power factor correction (PFC) to convert a universal ac-input voltage (95V to 264Vac) to 12Vdc/20A, 24Vdc/10A, 48Vdc/5A, 72Vdc/3.5A, 110Vdc/2.2A or 125Vdc/2.0A continuous. A DC-input version, which offers an 95-350Vdc input range, is also available. Typical conversion efficiency is 80% at full load.

The unit has large headroom and can be customized for up to 400W output power, depending on output voltage required. An optional built-in redundancy diode allows for parallel and N+1 operation.

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 EN55032 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 designed for compliance with EN62368-1 and equivalent safety standards.

Designed for operation in extreme environments, the units are fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating. This ensures protection from high levels of shock and vibration, moisture and other contaminants. The power supplies also meet environmental criteria as stipulated in MIL-810C, D. Cooling is by conduction via a base plate to a heatsinking surface. The unit is designed for continuous operation at +70°C when installed on an appropriate size heat-sinking surface.

The chassis measures 146 x 64 x 191 mm and is suitable for applications with space constraints; it is a full 1.7 inches shorter than the similar 300W encapsulated version.
