#163889 - PWM Dimming with SCR?? Responding to: ???'s previous message |
Juzar Gandhi said:
There was subject of PWM LED dimming : We use SCRs on ouput and drive as many LEDs required and in various colours and size:
I wanted to run good hardware adn we do it with 2051 : I want LED dimming by PWM : Please let me know details PWM Dimming with SCR ?? , You cannot control the Gate of an SCR with a PWM signal , once lached you will loose controle from its gate. It is MOSFET or other Transistors TIP series that would respond to a PWM signal not an SCR . -Ap |

| Maybe Unlikely, but... | 01/01/70 00:00 | |
| Oh that is universally known | 01/01/70 00:00 | |
| I did say, "Maybe Unlikely"... | 01/01/70 00:00 | |
| then it better be a high frequency | 01/01/70 00:00 | |
