DIN Rail Redundancy Module Delivers up to 40A in Slim Package
Design features low loss gating of AC/DC outputs for redundant or parallel operation. RECOM’s RACPRO1-RD40, a new cost-effective DIN rail redundancy module, comprises a pair of MOSFETs and their control, configured as high-efficiency gating diodes. This allows RECOM DIN rail AC/DCs to be connected in an n+1 redundant or parallel arrangement for critical applications where power must be maintained, even if an AC/DC goes off-line. In redundancy mode, each module can be used with a load of up to 20A, fed from two AC/DCs, rated at 20A each. In ‘parallel’ mode, the module can supply an output of up to 40A (60A/5s) over an ambient temperature range of -40°C to +70°C with only convection cooling. RD40 modules themselves can be paralleled for even higher currents. Maximum voltage drop for the module is just 140mV, representing an efficiency of up to 99.5% and 5W typical loss. The module is designed for nominal inputs between 12V and 48VDC with a range of 9V to 56VDC and has a reverse output voltage immunity of 63VDC (70VDC peak). The part is certified to IEC/EN/UL/CSA 62368-1 for safety and meets EN 61000-6-4 Class B emissions and EN 61000-6-2 immunity standards. No-load consumption is less than 200mW. Wide operating temperature, high reliability and a long lifetime of better than 268,000h at 40°C make the RACPRO1-RD40 suitable for harsh industrial environments. The module is just 43mm width, mounting is tool-less and electrical connections are push-in, angled at 25° for easy installation.
AC/DC DIN Rail Power Supplies and Accessories
AC/DC DIN Rail Power Supplies and Accessories The RACPRO1 series of industrial DIN rail AC/DC power supplies is compact, efficient, and includes single-phase input versions rated up to 480W and three-phase versions rated up to 960W. Additionally, the REDIIN series offers single-phase universal AC inputs and outputs rated up to 480W for cost-sensitive applications, without compromising performance in demanding industrial environments. The new REFIN series is super-slim and offered in the ‘step-shape’ format with up to 90W continuous rating. To complement these products, four-channel resettable e-Fuses are available in the DIN rail format rated up to 10A, as well as soon-to-be-announced redundancy diode modules.
Ultra-slim DIN Rail AC/DC Delivers 90W
RECOM ‘step-shape’ DIN rail PSU packs performance and features into miniature casing. RECOM’s new, cost effective REFIN2U-S90/24/CL DIN rail AC/DC boasts a 90W rating with a boost capability of 150% for 4.5s to allow for surge loads. Input voltage range is 85-276VAC, rated overvoltage category II (OVC II) up to 5000m altitude, while the output is nominal 24VDC, adjustable to 29VDC. The output has a constant current characteristic in overload and is rated LPS, NEC class 2 according to UL1310. The parts operate from -40°C to +70°C ambient, and a creditable 93.6% efficiency achieved contributes to cool running and long MTBF/lifetime ratings. The REFIN2U-S90/24/CL is presented in the popular ‘step-shape’ DIN rail format and is just 36mm in width, weighing in at only 151g. Extending mounting flanges allow the part to be panel-mounted if wished, and particular attention has been paid to eliminating acoustical noise – an important consideration in office or domestic installations. DIN rail mounting for the part is snap-on, and electrical connections are push-in for easy, tool-less installation. The parts are certified to international safety standards, have low no-load losses, and comply with IEC/EN EMC regulations. “This 90W DIN rail AC/DC is the current flagship of our REFIN range with a great combination of value, performance, and easy system integration” comments Michael Schrutka, MSc. product manager AC/DC of RECOM. “Check out the other 18W, 30W, and 60W parts in the range for more options”.
