This latest innovation offers the same 2U-width, stepped DIN rail design concept at a reduced price for lower power applications and is suitable for space-constrained flat distribution boards, particularly in home and building automation systems.
The REFIN2U-S30 is available with nominal outputs of 12 V DC and 24 V DC and offers a continuous power of 30 W. The units operate with a wide input range of 85–305 V AC and offer adjustable output ranges of 10.8 V DC to 13.2 V DC and 21.6 V DC to 26.4 V DC, respectively. Typical efficiency reaches 90%, while no-load power consumption is less than 100 mW.
With a width of only 36 mm and overall dimensions of 36 x 94 x 55 mm, the new series is designed for installations where distribution space is limited. The components use spring-loaded push-in terminals for solid or stranded cables, enabling tool-free and bushing-free connections. Furthermore, rear mounting tabs allow for direct installation on the back panel in any orientation, even without a DIN rail.
The REFIN2U-S30 is designed to deliver 30 W output from -40 °C to +55 °C worldwide and can operate in ambient temperatures up to +90 °C with derating. Protection features include short-circuit, overcurrent, and overvoltage protection, with hiccup mode and automatic recovery. Reinforced insulation provides 4 kV AC separation between input and output, and the converters are rated for OVC III operation up to 3000 m altitude and OVC II up to 5000 m.
For integration into systems, the new components meet the electromagnetic compatibility (EMC) requirements of EN IEC 61204-3 Class B and EN 55032 Class B, and are certified to UL62368-1, CAN/CSA-C22.2 No. 62368-1-19, IEC62368-1, and EN IEC 62368-1. The products are also classified as limited power supplies (LPS).
“With the launch of the REFIN2U-S30, RECOM is expanding the REFIN2U range on a common mechanical platform that allows designers to use different power levels while maintaining the same compact 2U form factor and installation concept,” says Michael Schrutka, MSc, AC/DC Product Manager at RECOM.
