We have problem about LED Blinking. Please see detail below.
We make sample LED 32W (80Vdc/340mA) by adjust circuit follow DER285>>see schematic in attached file.
LED have been installed by connect AC Line 220V phase to phase, LED is Blinking. >>see connection in attached file
If, LED connect by AC Line 220V phase to N, LED not Blinking.
So, LED Blinking caused from circuit or AC Line 220V phase to phase.
Please suggest about LED Blinking caused. Thank you very much.
Thank You & Best Regards,
