ARTERM01H110 Browse Inventory

Artesyn's ERM family of high-performance DC/DC converter modules are designed to meet the power demands and safety standard requirements of railway rolling stock applications.
They are protected from atmospheric conditions without additional conformal coating being required.
The ERM 50W and 75W models are encapsulated in a compact quarter-brick form factor with metal base-plate. The isolated base-plate with threaded inserts can accept an optional heat sink or be used to cold-wall mount the new modules.
The ERM 10W and 20W models are encapsulated in a 1-inch by 2-inch DIP package (25.4 x 50.8). An optional heat sink can help heat dissipation and improve performance at high operating temperatures.
