Main power switch assembly generally is installed in the battery compartment, connected to the battery positive terminal and eddy current retarder controller between. It is the main switch to control the eddy current retarder. When not in use for a long time, the main power switch of the eddy current retarder needs to be turned off.
The main function of the switching power supply is to cut high energy into countless low energies, and then transmit it to the output terminal, and the output terminal will also feedback the input terminal through the level of the output voltage. In this way, a stable output voltage can be achieved Effect.
