ERM01H36 is a 10-watt isolated DC-DC converter module from Artesyn's ERM series, specifically engineered for railway applications requiring high reliability and safety compliance. The module accepts an input voltage range of 18-75 Vdc and delivers a single 24V output at 0.41A with 86% efficiency at maximum load. It features 3000 Vac rms input-to-output isolation, wide 4:1 input range capability, and comprehensive protection including overcurrent (OCP), overvoltage (OVP), and overtemperature (OTP) protection. The converter operates across -40°C to +85°C ambient temperature range and meets critical railway safety standards including EN61368-1, EN50155, and EN50121-3-2 EMC requirements. Its compact 50.8 x 25.4 x 11 mm DIP package with encapsulated epoxy potting and remote on/off control makes it ideal for mission-critical railway power distribution systems where space efficiency and regulatory compliance are essential.
