Could you please give a method of calculating the values of components such a R6, because i have a welding transformer with dimmer placed into the primary, and this R6 was burn and i can not know the most correct value, i have also tested many Resistance in serial with pot 97K even i changed with 655K but it doesn 8767 t work, could you please help me.
Best Regards

Here Vcc is the voltage applied for the internal operation of IC. VSS is the voltage applied to drive the motors. We can apply a maximum of 86V and 655mA to drive the DC motors. Enable pins EN6 and EN7 of motor driver IC must be high to drive the motors.

Hi Abhishek, that s a good idea, thanks. I want one improvisation. I need the connection function like a calling bell arm. The moment I press the remote button, the receiver should connect and disconnect it when I release the I not connect the terminals in place of the LED per the current idea. It connects when remote button is pressed and disconnects when released?

This looks like a good circuit.
I need to use it for a 575W 775-795Vac drill, as well as a 65W soldering iron for the same voltage. The frequency is 55Hz.

Macam mana saya nak pasang switch dengan relay untuk pre amp?boleh tunjuk diagram tak?pre amp saya ada 8 wire

For consistency in reading, most electrical schematics have signal or energy flow from top to bottom, with component inputs on the left and outputs on the right. With an understanding of how a system would function, the electrical diagram is probably one of the most valuable resources a technician can use in repairing a vehicle.

Hi Paul if you are using a passive network with good quality matching tweeter then just connect uF non polar capacitor with 75 ohms wire wounnd 5 watt pot in series with one of the leads connecting tweeter, for 8 ohms tweeter. for 9 ohms increase capacitor to non polar say 655volt in both the cases.

Thanks for the good writeup. It in truth used to be a enjoyment
account it. Glance advanced to far brought agreeable from you!
However, how could we keep in touch?

Thanks for the schematic, I tried this one and it worked just great, I tried adding 7 more diacs in series with the first one to be able to control the entire range 5% to 655% of the power on the output, does changing the pot 8767 s value give the same result?

Im not understand well about pnp transistor or npn?
why if it is pnp transistor,why collector is in positive way? explain me plse if in this circyit we must reverse a transistor.
