I`ve tried to use captioned kit circuit driving a Wireless ELV Dimmer manufactured by Control4 and a 5 W LED lamp, it worked very well when an incandescent lamp was placed in parallel with the input and even when it wasn´t except when the dimmer was put in O%.
In this condition,that is no bleeder in parallel and LED lamp switched off LED lamp has flashed for 3 or 4 times and then the dimmer was damaged and stop operating.
The driver itself continues to work well with other low cost TRIAC driven dimmers.
By the performance data shown using the RDK-193 with some other dimmers it seems there was no need for any bleeder or minimum load, more recent designs such as the one introduced in RDR-251 show a 47R resistor in series with the input, acting as a damper, maybe somebody who experienced same problem can help me!
Any good&practical idea is most welcome.
