Control and commissioning

Parameter Specification
KNX dimming Built-in KNX interface, KNX certified and supporting KNX Data Secure. Minimum dimming level 0.5%, up to 100%, with OFF (0%) control; logarithmic or linear curve selection.
ETS commissioning Use the matching application database from ETS Online Catalogs or the MEAN WELL product catalog. Connect the bus interface, energize the supply and KNX bus, press the programming button, load the physical address (programming LED goes out on completion), then load the application/parameters and test the functions.
Configured functions Normal dimmer or staircase light; switching, relative/absolute dimming, on/off and dimming-value reports, lamp-failure reporting, lock functions, scenes 1–32 with scene learning, automatic functions 1–4, and adjustable bus-power-up behavior.
CLO and monitoring Constant Light Output compensates LED lumen depreciation by programmed current adjustment over operating time. The manual provides five scheduled CLO divisions with configurable factors; configure the luminaire accordingly. Operating-hour counting, lifetime pre-warning, voltage/current/power and energy feedback, cyclic temperature reports, adjustable temperature alarms, timed gradient dimming and lux-based characteristic correction are available.
PUSH and AC-monitor selection Configure the PUSH port for push dimming or AC input monitoring in ETS. Both require the KNX bus to be connected. For PUSH, connect the mechanical retractive button only between PUSH and AC/L; connection to AC/N causes a short circuit. Use the separate manual wiring diagram for AC/DC monitoring.
PUSH wiring limits Maximum cable length between the button and driver: 20 m. Local PUSH configuration supports up to 10 drivers on one common button. Separately configured ETS groups depend on group addresses and the project designer.
PUSH operation Short/long press actions and dimming direction are configurable in ETS; long-operation threshold defaults to 1 s and is selectable from 0.5 to 10 s. Enable local driver control if its output should follow PUSH signals; otherwise the port can send KNX switching signals for other devices. Staircase mode allows on/off only at this port.
KNX bus layout Manual design limits: 256 bus devices; 350 m from bus power supply to the furthest device; 700 m between two bus devices; 1000 m total bus line across all segments. These are bus-topology limits, not the one-button driver allowance.
Factory reset The dedicated KNX manual describes restoring factory settings by holding the programming button for more than 10 seconds. Recommission and verify the intended parameters afterward.

Input and protection

Parameter Specification
AC and DC input 100–305 VAC; 141–400 VDC. Frequency 47–63 Hz. Confirm the applicable DC wiring before connection.
Power factor Active PFC. At full load: ≥0.97 / 115 VAC; ≥0.95 / 230 VAC; ≥0.92 / 277 VAC.
Total harmonic distortion <10% at load ≥50% / 230 VAC or ≥75% / 277 VAC; <15% at load ≥50% / 115 VAC.
AC input current 0.35 A / 115 VAC; 0.18 A / 230 VAC; 0.15 A / 277 VAC.
Cold-start inrush 10 A typical, width 100 μs measured at 50% Ipeak, 230 VAC; per NEMA 410.
16 A circuit breaker loading 71 / 71 units on type B / type C respectively at 230 VAC, under catalog reference conditions. Verify the actual breaker and installation.
Leakage and standby Leakage <0.75 mA at 277 VAC. Standby <0.5 W with dimming OFF, measured at 230 VAC.
Setup and rise time 500 ms setup / 100 ms rise at 230 VAC; 1000 ms / 100 ms at 115 VAC. Setup is measured at the first cold start; turning the driver ON/OFF may increase setup time.
Short circuit Hiccup mode; automatically recovers after the fault is removed.
Overtemperature protection Stage 1 reduces loading to 75%; stage 2 reduces it to 50%. Automatically recovers after the fault is removed.

Thermal and environmental limits

Parameter Specification
Cooling and ambient limits Free-air convection. Published curves apply to horizontal mounting: 100% load from −25°C through +40°C ambient at 110 VAC, and through +50°C at 230 VAC. These curves end at the stated limits; no higher-temperature slope is specified.
Case temperature Tcase −25 to +85°C; maximum +85°C at the designated tc point. The case limit is distinct from ambient temperature.
Input/load derating At 60 Hz: 80% load at 100 VAC, rising to 100% at 110 VAC; 100% through 305 VAC. Apply input and thermal limits together.
Altitude derating For this fanless driver above 2000 m, reduce permissible ambient temperature by 3.5°C per additional 1000 m.
Humidity and storage Operating: 20–90% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X/Y/Z axis.
Typical life >50,000 operating hours when the tc point is about 70°C or lower.
MTBF 3949.8 / 338.5 thousand hours minimum: Telcordia SR-332 / MIL-HDBK-217F at 25°C, respectively.

Terminal-document difference The 2025-04-18 model catalog gives the TB1/TB2 values above. The earlier 2025.03 Ver 0 KNX manual instead lists stranded wire 0.823–2.08 mm² (14–18 AWG), stripping 10 mm, for AC/L, AC/N, PUSH and Vo±. Do not combine these into a wider allowed range; confirm the actual terminal/hardware and applicable instructions with MEAN WELL before wiring.
Optional equipment The catalog prints strain-relief cap reference 1**3XLC-SET: 1 bag / 50 pieces, 2 pieces per set. Confirm the complete order code and fit with MEAN WELL; do not expand the asterisks. The KNX manual uses the separately provided MEAN WELL KSI-01U USB interface as a commissioning example; it is not part of this driver.

Match the LED load, casing and terminal arrangement to this exact model; maintain the specified free-air-convection conditions and check the tc point in the completed installation. Follow the applicable manual for commissioning and any documented source differences.
