10W-120kHz High Voltage Supply Module-Designed for Audio Amplify Circuit

15W ~120kHz High Voltage Supply Module

[TYPE A]-High Freq-220V High Voltage Power Supply Module,Power Supply Module Std.

DANGER! Lethal Potentials Present
THIS MODULE CONTAINS DANGEROUS, HIGH VOLTAGE POTENTIALS. USE CAUTION.
DO NOT TOUCH ANY PART OF THE MODULE WHEN IT IS WORKING.

Description:
1. This is a newly designed high voltage power converters;Can accept 9~18V DC in,and output up to about 220V DC,range set by an on-board 3296 trimmer resistor(For Lower DC input you get lower MAX DC output).
2. Have increased the frequency up to about 120kHz to get more noiseless output to suit for the Audio amplifying circuit etc;
3. High quality transformer customized by factory with two shield layers inside 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. No audible noise;
6. Standard 0.1"(2.54mm) pins, easy to be used, can use DuPont-Wires etc.

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.For the heavy loader,the max output voltage may get a little bit drop,it's normal;
4.If needed,you can add an LC filter on the audio board by yourself;
5.Do not go over power/Heat/voltage/current, will damage the MOSFET or IC or Transformer on board.

Typical Usage:

For driving Audio AMP/NIXIE Tubes/Magic Eye Tubes and other applications requiring high DC voltage.

Typical Parameters:
(For reference only)

Input: 12V DC;
Output: 200V DC
Max Power Output: 10W;(For working under 10W for 24*7 condition,please take care of the mosfet's temperature,do not go over-heat.)
Max efficiency: 86.2%;
Output setting: Adjustable with a single trimmer resistor;
Module size: 45mm*33mm*13mm;

Simple test by myself:

By using a KTEC 12V/1.5A AC Power Adapter which is for my WD USB HARD DRIVER,and driving a regular FSL 15W 220V~240V E14 light bulb(which I bought for my refrigerator early),the results shown below:

Input:12V;
Output Voltage:190V with the light bulb turned on;
Output Current:53mA;
Power output:~10W;
Efficiency:83.9%;
No audible noise;
Worked fine under 24*7 condition,the max MOSFET temperature is about 65℃(degree C).
------------------------------------------------------------------------------------------------------

Output 230V 65mA output,Wout=15W;
(For testing only,do not work under this condition).
The Module can work,but after 2 hours,the mosfet over heat and been damaged.
