Buck Switching Regulator IC Positive Adjustable

Why do we use switching regulators?

The function of the voltage stabilizer is to stabilize the voltage. When the voltage is high, it will drop, and when the voltage is low, it will rise again. When buying a voltage stabilizer, it is recommended that you choose a voltage stabilizer that is three times larger than the actual power, because the voltage stabilizer has to overcome the surge impact of the mains and the starting impact of inductive loads (such as refrigerators, air conditioners, Motor and electric motor}
When choosing a contact type automatic voltage regulator when purchasing a voltage regulator, the rated output voltage regulator should have a larger margin than the transfer type automatic voltage regulator. Check the appearance quality and processing technology.
The operation of buttons, switches, etc. should be flexible and reliable. The Electronic Components should not loosen and shake the machine. There should be no rolling sound in the machine, otherwise it means there are foreign objects in the machine.
Reasonably choose the total rated output of the automatic voltage regulator, the total amount = the total power of household appliances × 3.
The shape and structure of the automatic voltage regulator include desktop, wall-mounted, counter-wall dual-purpose and floor-standing, etc. Different styles should be selected according to the installation location, main purpose, and installation capacity.
