RECOM has extended its range of DC/DC converters with a 3W version of their isolated RSH series in a surface-mount format with wide input ranges.

The RECOM RSH3 DC/DC converter is an addition to the RSH2 series featuring fully regulated, low-noise, and isolated 3W outputs in a surface mount package.

The series features nominal inputs of 12V (9–18V) and 24V (18–36V), which are useful for battery or bus-powered systems, while the outputs available are 5V, 12V, 15V, 24V, +/−12V, and +/−15V. The parts have short-circuit and overcurrent protection, and meet EN 55032 class A or B limits for input noise with a simple external filter. No minimum load is required, and the on/off control is standard.

The RSH3 series operates from −40°C to over +80°C without derating, making the products suitable for demanding industrial, test and measurement, and transport applications.

The isolation rating is 2kVDC/60s (optionally 3kVDC/60s) with UL/IEC/EN 62368-1 certification. The parts are RoHS-2 compliant.

The RSH3 series comes in a compact, lightweight DIP14 SMD case, available in tube or tape-and-reel packaging. The parts may be IR-oven or vapor-phase reflow soldered using industry-standard JEDEC profiles.

Matthew Dauterive, the DC/DC product manager of RECOM, comments: “The surface mount RSH3 series builds on the success of our 2W version and provides extra power for isolated on-board DC rails in the mains, and in the battery-powered equipment. The RSH3 will also find use in ground-loop isolation for industrial sensors and bus communication networks.”

The RSH3 series is available through all authorised RECOM distributors or can be availed by contacting the manufacturer directly. Samples can be requested via the RECOM website.
