DIN-rail PSUs go beyond rated power to boost productivity, saving both cost and size

Available now from Dengrove Electronic Components are new DIN-rail power supplies that can deliver up to 50% above rated power, which enables equipment to operate continuously during short-term overloads avoiding disruptive shutdown-reset, and allows designers to satisfy high system-demand peaks using smaller, lower-cost power supplies. The RECOM REDIN120 and REDIN240 power supplies, in 120W or 240W ratings, can fulfil a wide variety of applications in industrial automation, test and inspection equipment, vending systems, metering, building automation, communication or other equipment. Active power-factor correction (PFC) is built in, and all units are UL508 listed, UL60950-1/IEC60950-1 certified, and CE marked. Slimline cases, only 33mm wide for the REDIN120 and 46mm for the REDN240, allow conventional mounting leaving plenty of rail space for other modules, or sideways mounting for a lower profile. Several modules can be connected in series to deliver higher power or provide redundancy. Universal AC inputs simplify design-in to equipment for any market worldwide, and the REDIN120 series is available with 12V, 24V or 48V output. REDIN240 modules have 24V or 48V output. Extremely high efficiency of up to of up to 92.5% for REDIN120 and 94.3% for REDIN240 not only saves energy but also minimises internal heating to ensure longer sustained operation and greater reliability. The units can operate from -25C to +70C, and deliver full rated power at up to 60C. Over-temperature, overvoltage, short-circuit, and smart overload protection are all built in. Each module has red and green LED status indicators, as well as a ‘power good’ relay that can be used to drive a front-panel indicator or send an error signal to the PLC. Reliable operation in harsh environmental conditions and up to 3,000m altitude are ensured by the high-quality construction throughout, including conformal coating, long-life electrolytic capacitors, and transformers and coils containing high-grade ferrites.
