Page 2: Product Description
RODUCT ESCRIPTION The PYH200 series are board mount 200W DC-DC converters in a rugged half-brick housing with silicone potting. They provide a regulated and galvanically isolated output voltage. The most outstanding features of this series are the exceptionally wide input voltage range from 14V to 160V (12:1) and the high input/output isolation strength of 3000Vac. -
