The Artesyn/Advanced Energy ERM series is specifically designed to meet the power demands and safety standard requirements of railway rolling stock applications. An advanced circuit topology gives the Artesyn/Advanced Energy ERM family a very high efficiency of up to 92 percent. They are encapsulated in a compact quarter-brick form factor with a metal base plate to protect the module from atmospheric conditions without requiring an additional coating. In addition, the ERM family includes a reinforced insulation system to meet the general specification of high voltage input and low voltage output. Combined with high EMC immunity, these DC-DC converters are ideal for many demanding applications in railway and transport.
