The PFHI 5K-3U7 series of high input voltage, wide input range AC-DC switching power supplies with active power factor correction (PFC) are designed for heavy-duty industrial applications.

The power supplies operate over a 340-460Vac AC-input range; 400Vac 3-phase (3 wire connection) nominal input.  With available outputs of any fixed voltage 300V … 600Vdc, the units deliver up to 5kW continuous output power. Custom input/output voltages are available.

The PFHI 5K-3U7 units are equipped a built-in redundancy diode, which allows for several 5kW power supplies to be configured in parallel to create a 10kW, 15kW, 20kW or higher DC-power solution.

Active Power Factor Correction (PFC)

The PFHI 5K-3U7 units employ active power factor correction, which limits input current harmonics to achieve a PFC rating of 0.97 at full load for the entire input range. The  power supplies comply with EN61000-3-2 and EN61000‐3‐12 directives for low input harmonic distortion. Hold-up time is 5ms min at nominal input for 5% drop of the output voltage.

Safety standards, EMI and electronic protection

The PFHI 5K-3U7 power supplies comply with EN/UL60950-1 and equivalent industrial safety standards. Filtering on the input and output contributes to low output ripple and noise. The input meets EN55032 Class A with wide margins. Comprehensive Electronic protection includes 4300Vdc input-output isolation, inrush current limiting, output current limiting with short-circuit protection, output over-voltage protection and thermal shutdown in case of insufficient cooling.


The power supplies are cooled by high quality built-in fans and by conduction via the baseplate and are rated for continuous operation for full specification over a 0°C to +50°C temperature range. Wider temperature ranges are available on request.  

Rugged mechanical construction

The PFHI 5K-3U7 units are ruggedly constructed and designed to withstand high levels of shock and vibration (IEC 61373 Cat 1 A&B);  this ensures reliable operation in harsh environments. The internal board is conformal coated for immunity to moisture, humidity and airborne contaminants. The 3U7 chassis-mount unit measures 132 (3U) x 432 x 382 mm and the 3U7/19 rack-mount version 132 (3U) x 483 x 382 mm (H x W x D)
