PWM-60/120KN: Mean Well LED driver for KNX applications

Published : 02/12/2020 14:48:17

Mean Well, the world's leading power supply manufacturer, continues to promote KNX technology for building automation to create a green and sustainable society. In order to expand the KNX product range, the KNX PWM-60/120KN LED driver series was introduced to the market.

KNX Mean Well LED driver with 60 and 120 Watt output

PWM-KN LED driver Mean Well for KNX applications


PWM-KN series is an AC/DC LED driver featuring the constant voltage mode with PWM style output, which is able to maintain the colour temperature and the brightness homogeneity when driving all kinds of LED strips and the KNX interface to avoid using the complicated KNX-DALI gateway.

Mean Well PWM power supplies, uses the homonymous PWM (pulse-width modulation) modulation protocol, able to provide a constant and linear dimming, without affecting the color temperature of the led but acting only on the light intensity. The same dimming technology is applicable to the 12Vac lamps in an extremely simple way; simply connect the output of the PWM power supply to the bulb. In this way the Mean Well power supplies proposed by Digimax solve one of the main problems of chandelier manufacturers still linked, for constructive reasons, to an old technology.


PWM-KN operates from 90~305VAC and offers 12V& 24V 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~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.
