30W AC/DC range expanded with an open frame version

The RECOM RACM30-K/277 range of low-cost, board-mount AC/DCs has been expanded to include an open frame option, halving the weight compared with existing potted versions.

The highly efficient series provides 30W continuous and up to 36W peak power over an ambient temperature range from -40C to +55C in free air (depending on variant) and up to +90C with derating. Input range is extra-wide from 85VAC to 305VAC (120V to 430VDC), and outputs available are 5V, 12V, 15V, 24V, +/-12V, and +/-15V, rated as ‘limited power source’, fully regulated and protected. The parts are earth-free, with class II insulation and rated for Over-Voltage Category III (OVC III) and Pollution Degree 3 (PD3) environments up to 5000m altitude. Safety certifications include audio/video, ICT, test equipment, household, industrial, and MOPP medical, with 4kVAC/1 minute-rated isolation. The parts fulfil eco-design necessities for no-load/standby dissipation with near-flat efficiency curves down to light loads. All parts meet ‘class B’ EMC standards without external components with a wide margin, even with grounded outputs.

The product includes Molex electrical connectors for input and output and measures 76.2mm x 38.1mm x 23mm with four mechanical fixings for PCB pillars for convenient installation in end equipment.

Michael Schrutka, MSc, AC/DC product manager of RECOM, comments: “The open frame option now available makes the RACM30 range even more versatile and suits applications where minimisation of weight is important”.

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