Highly versatile board-mount AC/DCs extend comprehensive range

The wide range of low-power AC/DCs from RECOM has been extended with a 30W part in a class-leading package size of 1.6” x 2” x 1” (40mm x 52.5mm x 25.5mm). The highly efficient RACM30-K/277 series supplies 30W continuous power (36W peak) over an ambient range of -40C to +60C in free air and up to +90C with derating. The extra-wide input range is 85VAC to 305VAC (120V to 430VDC) and regulated, and fully protected outputs offered are 5V, 12V, 15V, 24V, +/-12V, and +/-15V, rated as ‘limited power source’. The class II insulation parts are rated for harsh over-voltage category III (OVC III) and pollution degree 3 (PD3) environments up to 5000m altitude, and safety certifications comprise audio/video, industrial, household, IT, test equipment, and MOPP medical, with 4kVAC/1 min, rated isolation. No-load/standby dissipation fulfils eco-design needs with near-flat efficiency curves down to light loads. All parts meet ‘class B’ EMC standards with a wide margin without external components, even with grounded outputs.

The series employs silicon-free encapsulation and is provided as a board-mount module with an industry-standard pinout. Optionally, the parts are offered with flying leads or panel-mounted with clip accessories to facilitate DIN-rail mounting.

Typical applications for the series include housekeeping power in EV chargers, industrial automation, lighting, IoT, medical, and smart energy systems.

Michael Schrutka, MSc AC/DC product manager of RECOM, comments: “These cost-effective AC/DCs are highly versatile. With their wide input range and comprehensive safety, EMC, and environmental specifications, they are a quick and easy design-in for almost any global application.”
