Hi folks, I am having a couple of strange issues and I"m hoping you all might be able to help me figure out what's going on. I'm powering two qb288 quantum boards with a Mean Well HLG-240H-48AB driver and followed the video LEDG posted to set up PWM dimming using an ESP32, PC817 optocoupler and 100 ...

This looks great, coming together really well. I have been working on my PWM fan control on my spare time here is my first take on it. I can provide the Node-Red export if anyone feels it will help them. Temperature Humidity PWM.PNG jaysal super late call back, but wondering if you could share the ...

An esp8266 can only output up to 3.3V on its gpio output. Without any additional hardware to raise that pwm signal to 10V, you will only get about the lower third output capacity of the driver. What additional hardware would be needed to raise the pwm signal to 10V in this situation? A level-shifte...

here's my S6 configuration working good here on a esp32+ L298n Mosfet driver ... The solution I came to doesn't require any other components other the the a PWM signal, an opto and some resistors. Been running very stable with multiple speed changes for over a month now without issue. Just wonderin...
