This is power battery saver circuit using an IC-555 timer. The lamp is controlled with a PWM mode by adjusting of potentiometer VR1. And, PNP power transistor drives a lamp. Sometimes…
The AC light dimmer circuit can control light bulb or speed AC motor, we use triac and SCR as main,and adjust potentiometer and switch,more circuits [...]
When change the value of R2 Intensity of Lamp change to this circuit shows the usability of Mosfet be Variable Resistor. By Q1 use N-Channel Power Mosfet. but what is…
This is the 3,000 watts Dimmer for inductor load example: the Electric Fan, AC motor,Electric drill etc. But most general dimmers is used for resistors load only such as lamp,…
This is 555 PWM dc motor controller circuit for dimmer a lamp or control speed of a DC motor. I used to suggests PWM model by use NE555 very cheap-popular [...]
