TDI Introduces New Rectifier/Battery Chargers in Distributed Power Architectures

Transistor Devices Inc. (TDI) announced its new signature 1000W universal input modules, which are described as high-reliability rectifier/battery chargers for TelCom applications (-54Vdc) or Front vEnds (+48Vdc) in distributed power architectures. Other outputs from 42 to 58Vdc are available on special order. The modules use conversion technology to achieve what is claimed to be 91% efficiency and their compact size. They accept remote program controller commands and report performance and fault conditions.

The matching 1U power shelf features a depth of just 359mm. It hosts three modules and is capable of delivering up to 3000W to the common load. Alternatively, the shelf can deliver 2000W of redundant power. The user may provide ac power to the shelf from a single phase or a balanced three-phase source. TDI offers tailored versions of the modules and shelves to meet particular needs.
