AC/DC Converter

Transformer Rectifier Units (TRU) converts aircraft primary AC power to 28VDC power from a 3-phase 115V, 400Hz generator per MIL-STD-704. Designed for minimum space and weight and maximum reliability, it offers excellent versatility for use in new designs or retrofits. The TRU's are using extremely rugged components which produce both high reliability and extreme overload capabilities. The output power meets the requirements for 28 volt systems per MIL-STD-704.
