DC/DC Converter ROD01.2

80 W DC converter

The 80-watt DC converter ROD01.2 with an output voltage of 19 V has a hardened and powder-coated aluminium housing and is dust, water, vibration, and shock proof. Tested according to various national and international military standards. The IP65 housing additionally ensures very good EMC characteristics with holes and a ground connection for fixed installation, e.g., in a protected vehicle.

Originally, the model was developed exclusively for the vehicles of the Bundeswehr [German Federal Army], which have a wide range input and place high demands on surge and transient protection of the on-board voltage according to VG96916T5 and the ground concept. However, it is now used in many national and international projects.

Mainly used for roda Notebooks and tablet PCs with MIL DC IN connectors; however, it is also available as an open frame circuit board.
