High Reliability Industrial Power Supply for Critical Applications

Absopulse Electronics’ HRW 40 provides high reliability supply voltage for a wide range of critical applications. These include large industrial systems where fail safe logic supply voltage enables detection and systematic system shut-down, and in fan drives where voltage failure could lead to entire system failure.

The HRW 40 delivers 40W at 12Vdc or 24Vdc. The input accepts any AC voltage from 85V to 264Vac and DC voltage from 100V to 360Vdc. Other input/output options as well as a redundant version are also available.

Field-proven technology, the use of components with established reliability and the complete avoidance of optocouplers in the feedback loop ensure outstanding reliability and an MBTF that well exceeds 500,000 hours at 45oC. The HRW 40 features full electronic protection and input/output filtering to meet EN55022 Class B EMI. It is designed to meet international safety approvals including IEC950 and related standards. The HRW 40 is convection cooled and rated over a 0oC to 50oC temperature range without de-rating. The unit’s open-frame design measures 3” x 5” with a maximum component height of 1.5”. Options include ruggedizing and conformal coating for harsh environment applications and enclosure in a 3.4” x 6.1” x 1.9” vented chassis. The HRW 40 unit is very competitively priced.
