KNX control and PWM dimming

Ordered configuration	KN: standard KNX control configuration. The catalog identifies KN as the standard stocked type; actual availability follows the order.
Dimming range	0–100%; minimum dimming level 0.01% as stated in the features.
Output PWM frequency	200–4000 Hz typical, user changeable via ETS; up to 4 kHz output dimming frequency.
PWM dimming principle	Brightness is controlled by varying the output-current duty cycle: duty cycle (%) = TON / T × 100%. The constant-voltage PWM output supports color-temperature retention and brightness uniformity with compatible LED strips or constant-voltage LED bulbs. The waveform shows the off interval at Io = 0 A.
Flicker-design reference	The catalog states design compliance with the IEEE 1789-2015 no-risk requirement and the EU Ecodesign stroboscopic visibility measure (SVM) requirement. The 0.01% minimum dimming level supports low-light applications such as cinemas.
KNX interface	Certified KNX protocol; apply the bus signal between KNX+ and KNX−. A KNX–DALI gateway is not required.
KNX polarity and separation	KNX+ is red and KNX− is black. Do not connect KNX− to the negative LED output (Vo− / −V). Keep the separate bus and LED-output pairs correctly identified.
ETS application and programming	The application database is available through ETS Online Catalogs or MEAN WELL's product catalog. The mechanical drawing locates the KNX programming button and LED.
KNX Data Secure	KNX Data Secure protects against manipulation in building automation and is configured in the ETS project. Specialist knowledge is required. The device certificate attached to the product is needed for first configuration; after configuration and preparation for daily operation, remove it as recommended and store it securely.
ETS switch parameters	Turn-on brightness, dimming speed for switching on/off, switch telegram and status, and switch-on/off delay.
ETS dimming and brightness parameters	Dimming speed over 0–100%; permission to switch on via relative dimming; transition speed between brightness values; permission to set switch-on/off brightness by value; brightness value and status. Further parameters are documented in the ETS application database and instruction manual.
Internal oscillator distinction	The block diagram identifies PFC fosc 50–120 kHz and internal PWM fosc 60–130 kHz. These internal switching frequencies are separate from the 200–4000 Hz output dimming frequency.

Protection and operating limits

Overload protection	108–135% of rated output power; hiccup mode or constant-current limiting, with automatic recovery after the fault is removed.
Short-circuit protection	Output voltage shuts down; cycle power to recover.
Overvoltage protection	41–49 V; output voltage shuts down. Remove the fault and cycle power to recover.
Overtemperature protection	Output voltage shuts down; remove the fault and cycle power to recover.
Case-temperature operating range	Tcase −40 to +85°C; maximum case temperature +85°C. Follow the output-load curves and measure at the specified tc point.
Ambient-temperature load curve	Horizontal mounting: at 230 V AC, 100% load through +45°C ambient, decreasing to 50% at +70°C; at 110 V AC, 100% through +40°C, decreasing to 40% at +70°C. The −40 to −25°C region is marked for 230 V AC input only. Apply input-voltage and case-temperature limits at the same time.
Case-temperature load curve	The horizontal-mounting curve shows 100% load up to Tcase +85°C; the cold region below −25°C is restricted to 230 V AC input. This does not replace the ambient-temperature derating curve.
Low-input load curve	At 60 Hz: 80% load at 100 V AC, reaching 100% at 110 V AC and remaining at 100% through 305 V AC.
Working humidity	20–95% RH, non-condensing.
Storage conditions	−40 to +80°C; 10–95% RH.
Temperature coefficient	±0.03%/°C over 0–50°C.
Vibration	10–500 Hz, 5 G; 12 minutes per cycle, 72 minutes each along the X, Y and Z axes.
Altitude derating	For this fanless model, reduce the allowed ambient temperature by 3.5°C per 1000 m above 2000 m altitude.
Performance-curve conditions	The PF curve is referenced to Tcase +75°C. The THD and efficiency curves use the 48 V model at that case temperature, with 115/230/277 V AC curves; they are reference curves, not additional ratings for every model.
Typical lifetime	Typical life expectancy >50,000 hours when Tcase at the tc point (or TMP per DLC) is about +75°C or less. The lifetime graph shows decreasing expected life as case temperature rises; lifetime is not a warranty duration.
Reliability	MTBF minimum 1658.9k hours by Telcordia SR-332 (Bellcore); minimum 170.0k hours by MIL-HDBK-217F at +25°C.
Manufacturer warranty	5 years; refer to the manufacturer's applicable warranty statement.

Load applications	LED strips and constant-voltage LED bulbs for indoor, decorative and architectural lighting; low-level dimming applications include cinemas. Cove and industrial lighting are also listed.
Installation isolation and ventilation	Disconnect utility power before installation or maintenance and prevent accidental reconnection. Keep ventilation clear and do not stack objects on the unit; maintain 10–15 cm clearance when the adjacent device is a heat source.
Cable and thermal checks	Use approved primary and secondary cables with current ratings at least equal to the unit's applicable current. Keep the measured tc point within the product-label limit.
Complete-system EMC	The driver is a component for installation with final equipment. The final-equipment manufacturer must requalify EMC performance for the complete installation.
Additional safety application scope	Type HL is listed for Class I, Division 2 hazardous (classified) locations. BS EN/EN 60335-1 is a design reference, not an additional approval claim. The datasheet identifies suitability for emergency installations according to BS EN/EN 61347-2-13 Appendix J.
Capacitive-load and ErP restrictions	Connection to capacitive loads is not recommended. To meet the stated ErP lighting-fixture requirement, use this LED power supply behind a switch; do not leave it permanently connected to the mains.
Connector sealing condition	If waterproof connectors are fitted, ensure that the connection between driver and lighting fixture is tight to prevent water entering the system. This installation instruction does not establish an unspecified IP rating.

Installation and KNX commissioning guidance

Installation and service precautions	Use qualified personnel for fault examination; do not open the case yourself. Provide system-level insulation at interconnections and enclose single-insulated wiring. Check the strength of the mounting structure; use safety cables for bay-light applications. Do not immerse the unit in water. A damaged flexible cable must be replaced by the manufacturer, its service agent or a similarly qualified person.
KNX commissioning	Select the matching MEAN WELL LED-driver application in ETS. Connect the bus interface and bus supply, press the programming button so its red LED lights, then download the physical address; the LED goes out when the address is loaded. Download the application and parameters, then test operation. Use the ETS Online Catalog and application data matched to the supplied model and firmware.
KNX bus planning	The user manual lists a maximum of 256 devices, 350 m from the KNX supply to the furthest device, 700 m between two devices and 1000 m total cable on one line. These are KNX-bus planning limits, not AC-input or LED-output lead-length ratings. Follow the supplied connector version and keep KNX negative separate from output negative.
Switching, scenes and blocking	ETS provides switching, relative and absolute dimming, status feedback, selectable dimming curves, automatic functions and eight assignable scenes per channel from 64 scene numbers. Scene operation is disabled in staircase mode. Staircase lighting turns off after its configured duration, with optional pre-warning or permanent-ON override. Blocking priority is Block I, then Block II, then Permanent ON, then switching/dimming; commands are ignored while blocked. The DALI curve option is a curve selection, not a DALI bus interface.
Operating hours and constant light output	Operating hours are saved to flash every 10 minutes; a bus-power failure can lose the unsaved interval. Constant Light Output adjusts brightness from the configured LED ageing curve: PWM-60/120 use entered curve values, while PWM-200 also offers L70/L80/L90 presets that can be adjusted. This compensates LED lumen depreciation and is not a driver-life guarantee.
Temperature and power feedback	Ambient-temperature feedback is calculated as internal temperature minus a correction factor; it is not a separate ambient-sensor measurement. Configurable temperature alarms and shutdown use the selected thresholds and reset mode. Power feedback is calculated from configured actual LED-load watts multiplied by dimming level, optionally including CLO; it is not measured AC input power. The manual's 1–200 W configuration range does not increase this model's rated output. Configurable lamp-failure reports can detect output short circuit, open circuit or either condition; 1 indicates an alarm and 0 no detected alarm.
Manual version and parameter limits	The linked dedicated manual is August 2021 Version 2. Its older parameter pages include 0.5–100% brightness settings; use the matching ETS database and the 2026-02-04 model datasheet for the current 0.01% minimum-brightness specification. Do not treat an old parameter default as a guaranteed setting of the supplied unit. Its generic 90–305 VAC introduction does not replace this model's 100–305 VAC operating range.
KNX Data Secure commissioning	PWM-200KN supports KNX Data Secure with ETS5 version 5.5.0 or later. For secure commissioning, set a project password and enter or scan the device certificate's FDSK; ETS creates a device-specific tool key. Back up the key and project. Remove and securely store the device certificate after configuration. A factory reset deletes security data and requires the FDSK again; choosing unsecured commissioning disables this protection.
End-system EMC verification	This is a component power supply. Verify EMC in the completed system with the actual load, wiring and installation layout; component test results do not establish compliance of every finished installation. The EMI guidance's laboratory arrangement is a test example, not a product mounting-clearance specification.
