Lethal Potentials Present
LET ME CLARIFY FIRST:
THE USER IS WARNED THAT CAUTION MUST BE USED IN THE TESTING AND USE OF THE MODULE.
HIGH VOLTAGE, LETHAL POTENTIALS ARE PRESENT IN THIS MODULE. EXTREME CAUTION MUST BE USED IN WORKING WITH.
THIS MODULE CONTAINS DANGEROUS, HIGH VOLTAGE POTENTIALS. USE CAUTION.
DO NOT TOUCH ANY PART OF THE MODULE WHEN IT IS WORKING.
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 no over the MAX input voltage;
3. Module contains input reverse polarity protection;
4. For the heavy loader,the max output voltage may get drop,it's normal;
The HV10W series high voltage power converters are typical boost converters based on 34063 chip which can accept 9 to 18V DC input,and output up to ~210V DC(MAX) ,range set by an on-board 3296 trimmer resistor.
(For Lower DC input you get lower MAX DC output and for heavy loader you get lower MAX DC output,read the details below).
eg: With 12Vin,under 10W output,the MAX HV output is about 180VDC;
This is a very common circuit,the key point of the circuit is the selection of the Inductor and the Mosfet.
The max efficiency is 86.2%, even under 12Vin, 10W output condition,the convert efficiency can still be ~84%.
The frequency is about 65KHz(If wanna try other freq,you can change the cap on-board by yourself.).
For driving NIXIE Tubes,Magic Eye Tubes and other applications requiring high DC
Output: 180V DC;
Max Power Output: 10W;(If increase the input voltage may get more power.)
Max efficiency: 86.2%;
Output setting: Adjustable with a single trimmer resistor;
Module size: 32mm(L)*26mm(W)*14mm(H); (*17mm(H) with TO220 type power mosfet been installed).
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,the results shown below:
Input Current: 980mA;
Output voltage: 180V with the light bulb turned on;
Output Current: 55mA;
Power output: 9.9W;
No audible noise;
