RDR-382 for PWM dimming

Posted by: kokhon23mj on

Hi, may I know if RDR-382 can be use for PWM dimming direct from MCU?

Or it needs to convert from PWM signal to analog first?

Do you have the recommended circuit design or reference from other DER that convert PWM to analog? 

Please advise urgently.

it will not work directly with PWM dimming. THe board is set up for analog dimming.

to work with PWM dimming, add a RC fitler to integrate the PWM signal into a analoge voltage.

the RC values will depend on the output votlage and freq of your MCU.
