RECOM adds an open frame version to range of board-mount AC/DCs.

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

The RACM30-K/277/OF series provides 30W continuous and up to 36W peak power over an ambient temperature range from –40°C up to +55°C in free air (depending on variant) and up to +90°C 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 are rated for Over-Voltage Category III (OVC III) and Pollution Degree 3 (PD3) environments up to 5,000m altitude. Safety certifications include audio/video, ICT, test equipment, household, industrial, and MOPP medical, with 4kVAC/1 minute-rated isolation. The parts meet eco-design requirements 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 RACM30-K/277/OF product includes MolexTM electrical connectors for input and output and measures 76.2 x 38.1 x 23mm with four mechanical fixings for PCB pillars, for convenient installation in end-equipment.

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

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.”

Parts include a three-year warranty, and samples and OEM pricing are available from all authorised distributors or directly from RECOM.
