The RAC20-K series are highly efficient PCB-mount power conversion modules with ultra-low
energy losses especially in light load conditions, making them a benchmark for always-on and standby
mode operations, which are typically coming along with IoT and smart applications. The power supply
units cover worldwide mains input range of 85VAC up to 264VAC and come with international safety
certifications for industrial, AV and ITE as well as household standards. These AC/DC modules operate in
a temperature range of -40°C to +85°C and offer fully protected single or dual outputs as well as EMC
class B compliance without the need of any external components.
