2-kW AC/DC power supply with PFC-input

New Products |
The Absopulse Electronics PFH 2K series of rugged, industrial grade ac/dc switching power supplies with PFC-input deliver up to 2 kW continuous output power. Several units may be paralleled for even higher power. These power supplies convert a universal ac-input voltage (95-264 Vac) to 36-Vdc/60-A, 48-Vdc/40-A, 54-Vdc/37-A, 110-Vdc/18-A or 125-Vdc/16-A. 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 1 kW 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 1 kW. 

The design may also be used as a 1 kW 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. 

The devices meet EN61373/IEC61373 shock and vibration standards. The PFH 2K series are housed in ruggedly constructed 5 x 5 x 12.5 inch chassis. Cooling is by high quality internal fans, which provide sufficient airflow for operation from 0 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. 

The 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.
