AC/DC power supply features medical certification

RECOM offers its new AC/DC open-frame power supplies with the RACM600-L series. The module can provide 400/450W (115/230VAC) with convection cooling, while 600W is offered with continuously forced airflow. The product provides a universal 80-275VAC input and a single 24V output, adjustable +/-20%, rated at 25A. A standby output at 5V/0.5A is also available.

The series is intended for reliable and cost-effective operations in high-availability applications, including medical and process control, with high-grade components and conservative design margins. Certifications include 2 x MOPP medical safety (IEC/EN/CSA/ ANSI/AAMI-ES 60601-1) up to 3000m, with leakage current suitable for BF applications. Also, the module is certified to IEC 62368-1 for IT/multimedia/industrial applications, with reinforced safety isolation to 5000m operation. EMC curve ‘B’ compliance to EN 55032 is accomplished with a good margin with no external components. Surge and burst immunity is at ‘Level 4’.

The eries features an efficiency of up to 93% and may be paralleled for redundancy or increased output with internal OR-ing diodes and active current sharing. ON/OFF control, a power good signal and remote sensing are included, along with a PMBus interface, for remote control and monitoring. Comprehensive protection against over-current, over-temperature, over-voltage and short circuits is also included.

The device is in an open-frame, rugged, U-channel format of only 197mm x 102mm x 41mm (1U) and includes fixings for chassis-mounting. Operation is from -20C to +70C with derating.

RECOM’s AC/DC product manager, Michael Schrutka, MSc, comments: “The RACM600-L is a versatile and cost-effective solution for systems that need high reliability and a full range of features, such as medical equipment and automation control”.
