The new, fully encapsulated DC/DC converters are characterized by their compact design, high efficiency and reliability. In the power range 30W they are available both as print modules and for DIN Rail mounting with practical terminal blocks and detachable DIN Rail system. The controlled modules offer an external remote on-/off control and provide a cost-effective and space-saving solution for demanding environmental conditions. Typical fields of applications of the BDC series are decentralised power supplies as well as industrial, data and communication systems.
