General Description

This product line is a power distribution and stabilized output voltage aimed to provide 28Vdc/600W total power for 6 consumer loads. Each load is driven by 28Vdc and 12Amp max current. The unit enables the consumer loads to work free of concerns from power fluctuations as appears on the vehicle DC power bus per MIL-STD-1275. The products protect electronic equipment against transients, surges, over and under voltage fluctuations that are inherent in military land vehicles (as determined in MILSTD- 1275). This series consists of a variety of products to comply with all requirements of MIL-STD-1275, including polarity protection, power interrupts, short circuit protection and EMI protection. This series has full compliance with MIL-STD-461. Load appearance indication and self recovery electronic circuit-breaker for over current and short circuit protection are build-in (disable only the fault consumer). The product is capable of substantial hold up time function.
