DC-DC Converters (5,10,15,30,70,100 & 200 W)

The family of epoxy sealed (100 and 200 W), and hermetically sealed (5,10,15, 30 and 70 W), dc-dcconverter.jpg (115405 bytes)high density DC-DC converters is designed for military applications utilising distributed power architecture. The family offers state-of-the-art performance in terms of power density, efficiency, reliability, noise, and ease of operation. These converters are designed using latest soft switching technology and multilayer printed circuit boards (PCB) using planner magnetics. Efficient thermal management of active power devices ensures safe and reliable operation for base-plate temperature range of : -55 C to 110C. These converters have all standard features like over load/short circuit protection, over voltage protection, over temperature trip, output voltage trim facility, remote sense, current share, synchronisation, power good signal, etc. A set of  peripherals has also been developed, which could be utilised depending on the application requirement. DC-DC converters find wide applications in electronic systems and are manufactured by M/s Modular Systems and M/s Digitronics, Pune.
