28 VDC Power and System Interface Board for Aircraft
The Power and System Interface Board has been specially developed for aircraft. It creates an interface between the external units and the display inside the multi-purpose display used in aircraft. At the same time, it converts the power it receives from a 28 VDC source to other voltages required by the system. In case of power cuts, the system continues to feed for a sufficient time for safe shutdown. It complies with MIL-STD-704F and RTCA/DO-160E standard input supply voltage conditions. The power and signal inputs/outputs of the board are designed for DO-160E category 3 and category 4 lightning protection. The card has dual power inputs and can select main power and auxiliary power. It has three channels of DVI (650 Mbps), three channels of analog video input and one channel analog video output interface to provide the interface of the multi-function display (MFD).
