Description 20 Watt The RAC20-K series are highly efficient PCB-mount power conversion modules with ultra-low 3 energy losses especially in light load conditions, making them a benchmark for always-on and standby 2 x 1 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 305VAC and come with international safety Single and certifications for industrial, AV and ITE as well as household standards. These AC/DC modules operate in a temperature range of -40C to +85C with up to 5000m operating altitude and offer fully protected Dual Output single or dual outputs as well as EMC class B compliance without the need of any external components in floating connections. Modified versions for OVC III requirements are available on request. Selection Guide Part Input Output Output Efficiency Max.
