AC-DC LED Drivers Feature KNX Interface and Universal Input

MEAN WELL has added the PWM-KN series of ac-dc LED drivers featuring the constant voltage mode with pwm style output, which is able to maintain the color temperature and the brightness homogeneity when driving all kinds of LED strips and the KNX interface to avoid using the complicated KNX-DALI gateway.

PWM-KN operates from 90- to 305-Vac and offers 12Vdc & 24Vdc output models. Thanks to the high efficiency of up to 90%, with the fanless design, the entire series is able to operate for -40°C to 90°C case temperature under free air convection.

The minimal dimming level low to 0.5% is suitable for low light level applications e.g. cinema. The output frequency is changeable up to 4kHz to complaint IEEE 1789-2015 no risk requirement providing a great solution for health concern due to light flickering.
