Single Input Surge Protector(INH281M-3P)
A DC-power surge, or transient voltage, which is subjected to disturb of various loads in the system, is an increase in voltage significantly above the designnnnated level in the DC power supply network. If no protection, the high surge will cause some heavy damages to electronic components and devices.
A surge protector is applied in the input terminal of the power supply of the electronic devices. it adopts power components to monitor and repress the surge, and ensure the output voltage in an allowable level of the device. As soon as the energy was generated by the increased high surge voltage, it would be diverted into thermal energy and absorbed by the surge protector.The output voltage in the system retains a normal level, that would protect devices in the system from surges in power.
The Magic DC surge protector series, which have many advantages, such as super small volume, low watt consumption, high-reliability, current limiting, self-protection and input reverse protection, are ideal of repressing surge voltage in the fields of aviation and space flight applications. They have already been used by most aviation electronics equipments suppliers worldwidely.
