Electronics Power Supply / Management ac/dc power suppliesABSOPULSE ELECTRONICS PFHI 5K-3U7 series of high input voltage ac-dc power supplies with 3-phase active PFC-input. Units operate over a 340-460Vac ac-input range; 400Vac 3-phase nominal input. With available outputs of any fixed voltage of 300V thru 600Vdc, units deliver up to 5kW continuous output power. Products can be configured in parallel to create a 10kW, 15kW or 20kW dc-power solution. 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.
