1-kW convection cooled AC/DC power supply with PFC-Input and inherent redundancy supports rugged industrial applications.

The series is built with two PFC 319 internal modules, which have a well-established track record in numerous heavy-duty applications. This modular construction provides inherent redundancy; in the event of the failure of one internal module, the unit would remain functional at half power. Several PFL 1K units can be paralleled for higher output power.  This design can also be used as a 500 W redundant power supply. Indicators include a green “Output ON” LED that is visible on each internal module through the cooling slots.  An output fail alarm is available as an option.

The PFL 1K-XXF44T series are housed in a rugged low-profile convection cooled chassis with a total footprint of 267 x 64 x 353 mm and are suitable for 1 kW industrial applications where available height is restricted and where fans are not permissible.

These units are filtered to meet EN55022 EMI standards. 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 absence of fans, low component count, large design headroom, and the use of components with established reliability result in a high MTBF. 


Standard versions of the PFL 1K-XXF44T are priced in the $763 range each at quantities of 100.
