Custom 5V 12V switching power supply 220V input dual output VIPER12A switching power module Manufacturer

 5V/12V Fully isolated switching power supply module

LC VIPER 12A switching power supply module can output both 12V and 5V at the sample time .And they are fully isolated .It has function of over hot protection, over current protection and short circuit protection
Functions and features :
On board VIPER 12A professional switching power supply chip
Input voltage : AC 85V-264V
Output voltage :5v /12A, Total fixed power 5W
5V is main circuit of switching power supply.Voltage output is stable, even when the full load, voltage error is only about 0.1V.
12V is secondary circuit of Switch power supply .Empty load voltage is 12.1V ,The output voltage is 5V and 12V ,determined by the load and unload current at the output end
Ripple voltage: < 1%, no-load power: < 0.4w.
DC5V current output 0-700MA,DC12V current output 0-200MA
Have the function of temperature, over current and short circuit protection.
Hardware introduction
Board size :45*26mm
Board interface instruction :
L,N:Respectively connect the fire and zero lines of alternating current.;
V1,G1:The positive and negative terminals of the 5V power supply.;
V2,G2: The positive and negative terminals of the 12v power supply..
Simple test description: L and N connects to AC 220V, and measure that the output voltage between V1, G1 and V2 and G2 is 5V and 12V respectively.

Note: according to the characteristics of multiplex switching power supply, when the main 5 v single loads device , the output voltage is stable. When deputy circuit 12 v single loads device, the output voltage will decrease according to the increase of load current (such as, voltage could fall to around 8 v when vice circuit current is 200 mA).In this moment ,user can add a load on the main 5 v circuit ,and the larger of main circuit is , the greater the deputy circuit goes back . However, note that the total output power of the 2 channel should not exceed 5W.
