Lead achid battery charger, up to 3 battery

By -
This circuit ti charger battery cells up to 3 battery , this charger use an IC LM301A , IC LM334 and transistor 2N3906 for major surgery on this charger circuit. Maximum input voltage 14 volt for 5 battery. Ouput voltage 2,35 volt 180 mA for 1 battery. And the charger input voltage must be filtered DC that is at least 3 Volt higher than maximum required output voltage.


See battery charger circuit below :



This is charger battery circuit
Above circuit furnishes an initial voltage of 2.5 Volt per Cell at 25 degree celcius to rapidly charge a battery . the charging current decreases as the battery cahrges , and when the current drop 180 mA , the charging circuit reduces the output voltage  to 2.35 V per cell, leaving the battery in a fully charged state.

1500W Stereo Power Amplifier Schematic

Circuit Power Amplifier has a power output of up to 1500W RMS power amplifier circuit is often used to power sound systems keperlun for outdor. In the final image can be seen a series of power amplifiers using 10 sets of power transistors for the ending. This power amplifier circuit using a transistor amplifier from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A 1500W power amplifier circuits for this. Supply voltage needed by the power of this amplifier is the optimal working order symmetrical 130VDC (130VDC-130VDC ground). 1500W amplifier circuit below is a picture series of mono, stereo if you want to make it necessary to make two copies of the circuit. For more details can be viewed directly image the following 1500W power amplifier circuit. The series of High Power Amplifier 1500W With Transistor Click Image to view larger In the above series of power amplifer 1500W is equipped

TDA2030 complete tone control

At this time I present a series of amplifiers that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat. Schematics Layout PCB PCB design This amplifier is a mono amplifier type, can be modif for guitar amplifiers. If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.
