Mean Well OWA series 115W 12V LED driver noise-free with and without a dimmer. IP67 waterproof.
Several LED drivers have an unpleasant noisiness feature with dimmers. Typically it happens with PWM-dimmers and when power level is at about 80%. The power source starts to emit a high-frequency squeaking noise. This one does not have such a problem. By this kind of dimmer we mean an LED dimmer that is installed after LED driver. So this driver will not be dimmed but instead the dimming happens after the driver.
You can feel immediately that this is a high quality device. We recommend. This LED driver fares well in wet and also dusty surroundings. Regarding protections this one has it all. Fault, overload, overvoltage and overheat protection. When fault or overload protection is triggered, the LED driver starts to cut the power output and resumes normal operation when fault has been fixed. In practice this means flickering lights and the flickering will stop when fault has been fixed. Overvoltage and overheat protections work in shut down principle. LED driver cuts the power and re-powers itself when error has been resolved.
Benefits: No squeakiness, power plug ready, Mean well quality
