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 -40°C to +65°C, they are ideal for always-on and
standby mode operations in process automation, IoT and smart building applications.
