Converter SG3524 12VDC/ 230VAC 200W

It's a tension converter SG3524 12VDC/ 230VAC 200W. It is equipped with a ventilator driver and a circuit that prevents the battery discharge. Also measurement of battery tension on three diodes. It can be powered on only when the microswitch is being pressed. The device has internal accumulators (2x 7,2Ah), but it is also possible to connect external power supply thanks to the alligator clips. When two switches in the center of the panel are switched on, 12V from accumulators go to the alligator clips. Banana sockets are useful during charging each accumulator separately. They are separated by a special double-joint switch. It was because of the charger has 500mA, so two accumulators would cause too much charge while loading.
Radiators start to heat up at charge range 100W, at maximum power they are about 60 degrees Celsius – then the ventilator is activated and the temperature descreases.
Things changed in the converter:

• rm83z transmitter into a car transmitter 30A
• irfp240 transistors into irfz44n
