smps is it possible to increase dc output

[irvynejay]

Hello I just want to ask if this is possible to improvise or increase output of this smps
its rated 110-220 47-64khz 12v 15 ampere

its using 2sc2625 power output and KA7500B SMPS Controller driver

pls see photos

Hi Irvynejay
greetings sir this smps 2500 watt easy to diy then clone it
warm regards

what increase of output your are refering to?

 

[irvynejay]

it only have 12 volts dc output could it be possible to make it higher like 60v to 75 volts dc?

 

[mikecarel]

Yes it can, for as long as your trafo can handle your computed windings. Refer to norazmi trends about TL494. KA7500 is the same controller as TL494, it only differs in pin assigment but similar applications.

 

[irvynejay]

ok ty sir mikecarel,,but norazmi used mosfet this smps use BTJ

Michelle yes easy to clone but how there are no value

 

[norazmi]

Irvy, my smps with TL494 also use BJT, read it, its about the same. Yes u can have more output voltage by adjust feedback and re-winding your trafo

 

[stewin]

the smps looks promising .

oh ok my bad thanx norazmi
