Description
The RAC04-xxS_DC/277 series are fully certified single and dual regulated AC/DC converters in an encapsulated
PCB-mount package style with 3.75kVAC isolation and very low stand-by power consumption. The modules are
suitable for worldwide use due to their wide input voltage range from 80VAC to 305VAC. Possible uses include
home automation, standby applications and industrial controls.
