RECOM Power RAC20NE-K/277 AC/DC Power Supplies

RECOM Power RAC20NE-K/277 AC/DC Power Supplies offer a wide input range of 80VAC to 305VAC and are ideal for new energy, industrial automation, machinery, and the Internet of Things (IoT) applications. The RAC20NE-K series features open-frame or encapsulated solder-mount built-in power supplies optimized for energy management, monitoring, and actuator operation. The compact AC/DC modules meet the increased demands for ambient temperatures, high immunity levels against transients, adopted insulation barriers, electromagnetic compatibility (EMC) interference freedom with secondary ground connection, as well as low power loss in full load operation, sleep mode, and standby mode.

The RAC20NE-K/277/EPID variant from RECOM Power is shaped to flexibly fit into different mounting conditions, including back-panel mounting with screws and clipping onto DIN rails. The devices are IP40 ingress protected aside from the push-in terminals for tool-free connection of wire cross-sections of up to 2.5mm2. The compact class II AC/DC power supplies offer increased resistance to surges and are fully certified to a variety of safety standards.
