2kW ac/dc Power Supply with PFC-input and Inherent Redundancy for Heavy-duty Industrial Applications

The Absopulse Electronics PFH 2K series of rugged, industrial grade ac/dc switching power supplies with PFC-input deliver up to 2kW continuous output power. Several units may be paralleled for even higher power. These power supplies convert a universal ac-input voltage (95-264Vac) to 36Vdc/60A, 48Vdc/40A, 54Vdc/37A, 110Vdc/18A or 125Vdc/16A. Custom input and output options are available.

The PFH 2K series is built with two PFH 65F internal modules which utilize field-proven design topology to provide 1kW each. The modular construction of the series provides inherent redundancy: the failure of one internal module would result in a 50% drop in output power, while the unit remains functional at 1kW. This design may therefore also be used as a 1kW redundant power supply. A module fail alarm (Form C) indicates the loss of AC power. A green LED, which is visible on each internal module through the cooling slots, indicates an output "ON" condition.

Designed for operation in heavy-duty environments, the internal models are ruggedized and conformal coated for immunity to shock, vibration and moisture. They meet EN61373/IEC61373 shock and vibration standards. The PFH 2K series are housed in ruggedly constructed 5" x 5" x 12.5" chassis. Cooling is by high quality internal fans, which provide sufficient airflow for operation from 0ºC to 50ºC cold-plate temperature without de-rating. Extended temperature ranges, including for sub-zero operating conditions, are also available.

The power factor is corrected to a minimum of 0.97 at full load for the entire input range, in compliance with the EN6100-3-2 directive for low input harmonic distortion. These units are filtered to meet EN55022 EMI standards. Full electronic protection minimizes the possibility of failure due to abnormal operating conditions, including application errors. Generous design headroom and the use of designed-in components with established reliability result in a high MTBF.

Standard versions of the PFH 2K are priced in the C$860 range each at quantities of 100. For quotation and availability, please contact Tony Szullo at tony@absopulse.com or telephone +1-613-836-3511.
