Description

The PWM KN series is a 60W AC/DC LED driver featuring constant voltage mode with PWM style output. It maintains color temperature and brightness homogeneity when driving all kinds of LED strips and constant voltage LED bulbs. The built-in KNX interface eliminates the need for a complicated KNX-DALI gateway.

The PWM KN operates from 90~305VAC and offers models with output voltage 12V and 24V. With high efficiency up to 89% and a fanless design, the series operates from -35°C to +90°C case temperature under free air convection.

The minimal dimming level of 0.01% is suitable for low light level applications, such as cinemas. The output frequency is changeable up to 4KHz, compliant with IEEE1789-2015 no risk requirement and EU Ecodesign stroboscopic visibility measure (SVM) requirement, providing a great solution for health concerns related to light flickering.

Model Encoding

The model encoding follows a pattern: PWM-60-24, where '60' indicates wattage, and '24' indicates the rated output voltage (12V or 24V).

Specifications

Notes:

• 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25°C of ambient temperature.
• 2. De-rating may be needed under low input voltages. Please refer to "STATIC CHARACTERISTIC" sections for details.
• 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. 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. 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°C or less.
• 6. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
• 7. The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
• 8. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf

Dimming Operation

The dimming principle for PWM style output is achieved by varying the duty cycle of the output current.

Output DC current waveform: The output current is a pulsed DC signal. The duty cycle, which is the ratio of the ON time (TON) to the total period (T), determines the brightness. The formula is: Duty cycle (%) = (TON / T) × 100%.

The output PWM frequency can be up to 4KHz.

KNX Interface: Apply KNX signal between KNX+ and KNX-. The application program (database) can be downloaded via Online Catalogs from ETS or via http://www.meanwell.com/productCatalog.aspx.

Performance Characteristics

Output Load vs Temperature

These graphs illustrate the relationship between load percentage and temperature. The 'Output Load vs Temperature' graphs show derating curves for ambient temperature (Ta) and case temperature (Tcase). For example, at 230VAC input, the maximum load (100%) is maintained up to a certain temperature threshold, beyond which the load capacity decreases.

Static Characteristic

The 'Static Characteristic' graph demonstrates the output load percentage versus input voltage (60Hz). It indicates that derating may be needed under low input voltage conditions to maintain stable operation.

Power Factor (PF) Characteristic

The 'Power Factor (PF) Characteristic' graph shows the power factor performance across different load percentages at 75°C case temperature for 115V, 230V, and 277V input voltages. PF generally remains high across the load range.

Total Harmonic Distortion (THD)

The 'Total Harmonic Distortion (THD)' graph, shown for a 24V model at 75°C case temperature, plots THD against load percentage for 115VAC, 230VAC, and 277VAC input voltages. THD is generally low, especially at higher load percentages.

Efficiency vs Load

The 'Efficiency vs Load' graphs, shown for a 24V model at 75°C case temperature, plot efficiency (%) against load percentage for 115V, 230V, and 277V input voltages. The PWM-60-KN series achieves high working efficiency, up to 89%.

Life Time

The 'Life Time' graph shows the expected lifetime in thousands of hours (Kh) versus case temperature (Tcase). The lifetime is typically over 100 Kh up to a Tcase of approximately 65°C, after which it decreases as the case temperature increases.

Block Diagram

The block diagram outlines the internal functional stages of the PWM-60-KN series LED driver. It includes an EMI Filter & Rectifiers, PFC Circuit, Power Switching, PWM & PFC Control, Rectifiers & Filter, Dimming Circuit, and Detection Circuit. Protection features like OTP (Over Temperature Protection), OLP (Over Load Protection), and OVP (Over Voltage Protection) are integrated. The KNX interface is shown connecting to the KNX Bus.

Note: The PWM fosc (switching frequency) indicated in the block diagram is related to the internal power factor correction and switching stages, not the output PWM dimming frequency.

Mechanical Specification

The unit dimensions are 150mm (Length) x 53mm (Width) x 35mm (Height), with a tolerance of ±1mm. The KNX programming button & LED are located on the unit, and a KNX connector is included.

The mechanical view shows input connections (AC/L Brown, AC/N Blue) and output connections (Vo+ Red, Vo- Black for power; KNX+ Red, KNX- Black for KNX bus).

Recommend Mounting Direction

The recommended mounting direction is typically horizontal, with the unit oriented so that the input and output cables are directed downwards for optimal heat dissipation and cable management.

Installation Manual

Connection for KNX-type

The connection diagram shows the AC input (Brown/Blue wires) connected to the AC mains. The DC output (Red/Black wires) connects to the LED strip or constant voltage LED bulb. The KNX interface (Red/Black wires) connects to the KNX Bus.

The PWM KN series can be ETS addressing/programming without connecting to AC mains.

Cautions

• Before commencing any installation or maintenance work, please disconnect the power supply from the utility and ensure it cannot be re-connected inadvertently.
• Keep proper ventilation around the unit and do not stack any object on it. Maintain a 10-15 cm clearance from adjacent heat sources.
• Mounting orientations other than standard or operation under high ambient temperature may increase internal component temperature and require output current derating.
• The current rating of approved primary/secondary cables should be greater than or equal to that of the unit. Refer to its specification.
• The 'Tc max.' is identified on the product label. Ensure the temperature at the Tc point does not exceed the limit.
• DO NOT connect "KNX- to Vo-".
• The power supply is considered a component to be operated in combination with final equipment. EMC performance is affected by the complete installation; therefore, final equipment manufacturers must re-qualify EMC Directive on the complete installation.
