rdr-801 LED driver output voltage issues

Posted by: sree@crocuslabs.com on Tue, 10/05/2021

We are using RDR-801 LED driver for our LED lights. 

Many drivers failing to provide the output after 10 min use. 

And slowly some switching sound I can hear. As the intended output voltage is 48V after a few min goes down to 30V and then goes till 11 V and is not stable.

And in some cases, LEDs are blinking slowly. Can you please help us as we are doing a new design using this chipset?

 

thanks,

Sree

Hi Sree,

Thank you for your interest in our products. May I know the input and output conditions of your application?

  • input voltage and frequency
  • ambient temperature of application (if there are thermal data gathered on individual components, it would be better)
  • type of dimming mode used
  • load specifications
  • modifications on unit
  • failure mode (blinking output, lower output voltage, etc.)

If you can provide these then we will have more of an idea on the failure that is happening.

Hi....Contingent upon the steady ebb and flow driver being utilized, the voltage yield in its "open-load" state might give you readings that are fluctuating all over the full scope of the voltage yield window as it might attempt to siphon the decent momentum. Some of the time a run of the mill DC multi-meter will struggle perusing this since apparently as an AC voltage rather than a DC voltage. The yield may likewise be sitting at min or max of the voltage yield window. As a rule, you should have a heap on the yield to fit in the voltage yield range and furthermore the momentum yield rating of the driver.
