  • Not compatible with SKU 190132 dimmer

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    Very small for 7 watts at 330mA. Works fine when connected directly to 7w COB LED. My device was running about 310mA - almost within tolerance.

    Cons:

    Runs fairly warm, may melt some plastics around it, doesn't work with SKU 190132 RF dimmer even though power supply specs say voltage is within dimmer range. The 7w COB LED SKU 141720 flickers at anything less than 100% brightness. I didnt hook a scope up, but my guess is that the PWM causes the power supply driver to flicker from noise. Dimmer worked fine with bench power supply at 22v, 12v switcher + 12v LED panel, and linear power adapter.

    OtherThoughts:

    Not good for use with PWM dimmer circuits. Maybe it's a quality control issue, maybe not.

    Bottomline:

    Simple switcher constant current driver. Don't expect great things from this device.
