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 Single and 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 Dual Output 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.
