Intertek Class 2 Power Supply
12v 9w power supply module is a modular package of discrete components on the switching power supply, so as to form a modular power supply with smaller volume and higher power density. Its internal circuit is also a switching power supply.
Description
Description
Class 2 transformer 120v 60hz 12V for switching power supply.DC / DC conversion is to convert a fixed DC voltage into a variable DC voltage, also known as DC chopper. There are two working modes of chopper, one is pulse width modulation mode, TS unchanged, changing ton (general), and the other is frequency modulation mode, ton unchanged, changing TS (easy to generate interference).
