The Difference Between Switch Power Supply And Linear Power Supply

  • Author:Lancy He

  Usually,there are two types of power supply in our market, one is switch power supply, the other is linear power supply. Switch power supply is small, but linear power supply is big and heavy, and also has a big transforming loop on it. The main advantages of switch power supply is high efficiency, low heat, small and large current output. But its disadvantages is also obviously, the power supply itself likely to have ripple and noise.  The voltage feedback circuit of linear power supply is working in the linear status.  The technology of  linear power is mature,low costs and stable. What's more, it ripple is small with no noise but its volume is larger than switch power supply, and will need a large input voltage.

  Although linear power supply current output is small, and the input voltage is always give a big affect to output voltage, as long as the input voltage is stable, linear power supply voltage is relatively stable and with smaller voice.

  So generally we recommended to use dual power supply system. Access control and access control reader can use  linear power supply, switch power supply can be used on locks. Use the switch to lock the power supply.

  As a good power supply manufacturer china, we always try our best to give our customer the best suggestion. And we also will give our customers best china power supply. So, if you are finding a good power supply factory china, don't hesitate, just find Proyu!
