UCD 25 watts to 1200 watts using 2 mosfets

hi hadi regarding your question : i etched manojs amp but i did not make it because of complex issues i wanted a simple powerful amp.

i made irs 900d it is simple and very silent i think because it is non ucd that is why it is noiseless . but i plan to use it with manoj power supply board because of the oc protection in manoj power supply board. will post pictures soon
 
thanks to sir manoj

Hi Hadi,

you should connect -75v(or your supply voltage what you given) supply to PIN 13 of IR2110.

and your car cd player you connected from 12V BAT or SMPS(12V)???

Hi Hadi,
For BIAS connection +12V line connected to (+) sign and -12V/GND line connected to (-) sign and (-)sign should be connected to -30V supply(without this amp will not work). no connection for center leg.

do not use same 12v for bias and CAR CD Player, it will damage your amp/cd player. use separate supply.
