Advanced Energy ERM

ERM Rail Series PCB DC-DC Power Supplies

High-performance isolated DC-DC power supplies for rail applications.

Supplier: Advanced Energy

Technology type: PCB DC/DC Power Supplies

Artesyn’s ERM series is specifically designed to meet the power demands and safety standard requirements of railway rolling stock applications. An advanced circuit topology gives Artesyn’s 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.
