Cost-efficient and Reliable 140W AC/DC

02-07-2024 | RECOM Power | Power

Chassis-mount AC/DCs from RECOM feature high peak power rating, case, and connector options.

Users now have the option to select a fully featured chassis mount AC/DC with comprehensive certifications at a low price point. The new RACM140E-K range is obtainable as an open-frame or optionally enclosed part, sized 147mm x 81.5mm x 38mm (40mm enclosed) with industry-standard 3" x 5" fixing positions and extra mounting wingers. Terminations are by pin header or optionally push-in connectors for enclosed versions, allowing easy integration in the end application. Input is universal AC, and single outputs available are 12, 15, 24, 36, or 48VDC, rated 140W continuous (36V/136.8W) and 210W peak for ten seconds for loads with high surge currents. The output voltage can be adjusted typically by +/-20% through a board-mounted trim potentiometer.

Certifications include IEC/EN60335-1, IEC/EN62368-1, and IEC/EN ANSI/AAMI60601-1 for medical applications rated 2MOPP and BF with low touch and leakage currents. EMC compliance is comprehensive, including 'Class B' with a good margin for conducted emissions. The parts are rated for pollution degree 2 environments and over-voltage category III up to 2000m altitude and OVC II to 5000m. The operating temperature is -40C to +90C with natural convection, with derating depending on the variant. No load consumption is typically 100mW, and the parts meet eco-design requirements for loads in standby mode.

"The RACM140E-K series is a great combination of performance, reliability and comprehensive certifications at a competitive price point," comments Michael Schrutka, MSc of RECOM. "The high boost power rating for ten seconds is a bonus for high surge loads, potentially avoiding the need for a larger and more expensive AC/DC."

Typical product applications include building and home automation, datacom and telecom, medical, industrial, infrastructure, e-mobility and test and measurement.
