New-[HV12-Pro]-12W-Small Size-12V to 380V(Max) High Efficiency PSU for Audio Application

High efficiency High Voltage 380V (Max) Power Supply Modulefor Audio

 

Brand New Design,High Frequency,High Power,Hig Efficiency.

Have tested by myself,under 10W output,working in 24*7 condition,the module got almost no heat!

 

Very small size,only 43mm*24mm, with STD. Pins,can accept 12V~15V input,output is adjustable;

Can output 380V(Max) with loader on at ~10W power with no problem;

Max efficiency up to 89.5%,even under the 380V,25mA ~10W output condition,still have about 85% efficienty.(*May have ~3% error because of the accuracy of the equipments);

 

Description:
1. This is a newly designed high voltage power converters;Can accept 12~15V DC in,and output  ~380V DC(Max), output is adjustable by using a ex. resistor;
2. Have increased the frequency up to about 120kHz to get more noiseless output;
3. High quality transformer on-board to low down the noise;
4. It contains an ENABLE pin to turn the convert on/off,and can be controlled by an regular logic signal,like a MCU's GPIO PIN.
5. Module contains input reverse polarity protection and short protection circuit via current limiting.
6. No audible noise;
7. Standard 0.1"(2.54mm) pins, easy to be used, can use DuPont-Wires etc.

(* Remember to seperate the dupont-wire when connect to the 380V part.)

Tips:
1.Please control the input current in <=1A for the low heat working state,if need more power output,you can increase the input voltage;
2.Please use high quality and stable input DC source,make sure the max input voltage is not over the max range;
3.We recommend using 12V as input;If need more output power can use 15V input.
4.Do not go over power/Heat/voltage/current, will damage the MOSFET or IC or Transformer on board.

 

Simple test by myself:

By using 12V input,output 380V drive a 15K Std. Resistor,the results shown below:

 

Input:12V, 0.95A;
Output Voltage:380V with the 15K load on;

 

Output Current: 25.3mA;

 

Power output: 9.62W;

 

Efficiency: ~84.33%;

 

No audible noise;
