Features Regulated Converter * * * * * * * Wide input range 85-305Vac Operating temperature range: -40C to +80C Ultra-high efficiency over entire load range No external components necessary Household certification IEC/EN60335 Class II installations (without FG) 140% Peak load capability Description The RAC10-K/277 series are highly efficient PCB-Mount power conversion modules with ultra-low energy losses even in light load conditions. Built for worldwide usage, the AC/DC units cover an enhanced mains input range of 85Vac up to 305Vac and come with international safety certifications for both industrial and household standards. These AC/DC modules offer fully protected single or dual outputs as well as EMC class B compliance without the need of any external components. The 140% peak power capability makes the RAC10-K/277 series suitable for inductive, high start-up current or nonlinear loads. With a full load temperature range of -40C to +65C, they are ideal for always-on and standby mode operations in process automation, IoT and smart building applications.
