Overview

PWM-60-24KN is the 24V output model of this series: rated current 2.5A, rated power 60W, typical efficiency 89%.

PWM KN series is a 60W 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 constant voltage LED bulbs.The built-in KNX interface is to avoid using the complicated KNX-DALI gateway. PWM KN operates from 90~305VAC and offers two models with output voltage 12V and 24V.Thanks to the high efficiency up to 89%, with the fanless design, the entire series is able to operate for -35℃ ~ +90℃ case temperature under free air convection. The minimal dimming level low to 0.01% is suitable for low light level applications e.g. cinema. The output frequency is changeable up to 4KHz compliant IEEE1789-2015 no risk requirement and EU Ecodesign stroboscopic visibility measure (SVM) requirement providing a great solution for health concern due to light flickering.

  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  3. 3. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
  4. 4. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
  5. 5. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.

FAQ

Can I use the PWM-60-24KN in a KNX smart home lighting system?

Yes. The PWM-60-24KN features a built-in KNX interface, allowing it to be directly controlled over a KNX bus for dimming and switching without requiring a separate KNX-DALI gateway. This simplifies wiring and reduces system cost in KNX-based residential or commercial installations.

Is the PWM-60-24KN suitable for outdoor LED strip installations controlled via KNX?

Yes. The IP67 waterproof rating means the driver can be mounted in outdoor enclosures exposed to rain and wet conditions, while the -40°C to +90°C operating range handles both cold winter and hot summer environments. KNX dimming control is maintained over the bus regardless of location.

What is the advantage of the PWM-60-24KN over a standard driver plus KNX-DALI gateway?

The PWM-60-24KN integrates the KNX interface directly into the driver, eliminating the need for a separate KNX-DALI gateway in the installation. This reduces hardware cost, cabinet space, and potential failure points. The standby power consumption is also rated below 0.5W.

How much 24V LED strip can the PWM-60-24KN drive?

The PWM-60-24KN delivers up to 60W at 24V and 2.5A. For a 15 W/m strip, that allows approximately 4 meters; for a 10 W/m strip, up to 6 meters. Always check your strip's rated power per meter, and derate the driver to 80% (48W effective) for continuous operation.

Can the PWM-60-24KN be used for zone-controlled hotel corridor lighting on a KNX network?

Yes. This driver is well-suited for zone lighting in hospitality environments where KNX is the building automation backbone. Each driver can be individually addressed on the KNX bus, enabling scene control and dimming per zone without additional gateways.

Does the active PFC function on the PWM-60-24KN matter for large installations?

Yes. The built-in active power factor correction (PFC) reduces reactive power on the supply line, which is particularly valuable when many drivers are running in parallel in commercial buildings. It helps meet power quality requirements and reduces electrical infrastructure loading.
