| Dimming meanwell led driver |

hi so ive been building some cob led lamps with Chinese boost drivers and they worked out quite well now ive upgraded to a meanwell dc to dc boost driver LDH-45 , seems to be the only brand name boost driver on the market it has a dimming function but it requires voltage or pwm input , not a simple 10k pot that would make for a neat build i have bought a tiny module that outputs 0.8v , this activates the dimming but not down to a low enough level , it seems i need 0.25v to get full dimming i dont know how to get the 0.25v i need i dont want to use a bulky ebay pwm module , and the requirements seem to specify a certain type of pwm anyway any ideas ?? |

here is a picture of the lamp i built |

I'm not familiar with these. But, isn't as simple as adding a pot and resistor??? |
| daniel444:
thanks! your suggestion has worked i didn't realize it was so simple |

They make them to be easy! If you want digital control instead, you just feed your PWM signal into the relevant terminal. |
