        28.5V DC power supply

        This series of products is 28.5V DC power supply which designed and manufactured for aviation and military electrical and electronic equipment with high frequency power electronic switching technology. It can be used in aircraft and airborne equipment, radar, navigation and other military electronic equipment, and other needs 28.5V DC power supply of the occasion, is the SCR power generation products.
        28.5V DC power supply

        1.The power devices using a new generation of IGBT, IGBT switching mode using the advantages of high-frequency low-loss, the completion of energy conversion, with small size, light weight, high efficiency, high reliability characteristics.
        2. Current mode control using full-bridge converter, PWM control and slope compensation technology, without the need for series of anti-bias magnetic capacitor, with dynamic response fast, shock load capacity, over-current protection and reliable advantages.
        3. Intelligent monitoring using micro-single-chip computer to complete the intelligent power monitoring, LED / LCD digital panel display power operating parameters and working conditions; with fault self-diagnostic function, can remember the recent failure to improve maintainability.
        4.All the functional units and modules are designed as modular structure, through the series expansion of components, small size, high efficiency, reliability and maintainability.
        5.Machine adopts 19 "standard chassis structure, can be used alone or installed rack.
