- Can handle many LEDs in series. - Good quality PCB - Efficiency is high, measured 96% (25 V input, 24V LED output) without rectifier. - Uses Rubycon japanese capacitor - Analog or PWM dimmable (if you can solder small things) - Reliable, I have been running them for thousands of hours.
- Not 40V as specified, the chip can handle up to 30V and the cap on the board is good for 25V. - The dim input on the driver chip is not connected, would be nice with a solder pad for this.
The chip is ESD sensitive. Be careful with electrostatic discharge, especially on the DIM input. I have destroyed a few of them this way.
Very good value
