Description

Technical field

[0001] The invention relates to a power supply, in particular to an airborne airport wireless communication equipment power supply based on a vehicle-mounted equipment power supply. Background technique

[0002] figure 1 It is a mature power supply solution for vehicle equipment. This power supply equipment includes input connector (used to connect to input power), input filter and lightning protection device, AC-DC module (M3), DC-DC module (M4), Output filter device, output connector (used to connect to the load), where an input power enable pin is provided in the input connector, and the input power enable pin is used to directly control the on and off of the DC-DC module (M4) . Due to the limitation of weight and space, the input filter and lightning protection device and output filter device used in the above-mentioned vehicle equipment power supply are small in size and light in weight, and have excellent noise and lightning suppression performance. The ma...
