The difference between switching power supply and communication power supply
Usually through high-frequency shock electronic circuit (switching power supply) and access to more stable, more accurate, less interference voltage, only to supply communications equipment.
Communication power supply refers to the power supply of communication equipment. Can be batteries, 220V, AC, generator, dry cell, mobile phone battery, etc., because it is used for communication equipment,
The switching power supply is a high frequency oscillation electronic circuit used for voltage conversion. The main work is as follows: step-up or step-down, direct current is converted into alternating current, or alternating current is converted into direct current.
