Overtemperature protection	Output shuts down; remove the fault, then re-power to recover.
Working case temperature	−40 to +85°C; maximum case temperature +85°C, subject to derating.
Cooling and load derating	Free-air convection with recommended horizontal mounting. 100% through +50°C ambient, falling to 50% at +70°C. The −40°C to −25°C region is for 230 VAC input only. Keep Tc at or below +85°C; apply both ambient and input limits.
Input/load derating	At 60 Hz: 80% at 90 VAC, rising to 100% at 100 VAC; 100% through 305 VAC.

Temperature coefficient	±0.03%/°C over 0–50°C
Altitude derating	Above 2000 m, reduce the allowable ambient temperature by 3.5°C per additional 1000 m for this fanless design.
Vibration	10–500 Hz, 5 G, 12 minutes per cycle, 72 minutes along each X/Y/Z axis.

Control wiring and operation

Parameter	Specification
DALI operation	Apply the DALI signal between DA+ and DA−; DT6 brightness control. DALI supports 16 groups and 64 addresses. The catalog identifies the interface as primary-side; maintain the required insulation.
DALI polarity	The DA/DA2 DALI pair is polarity-insensitive; the wire labels do not imply a polar DC output.

Safety, insulation and compliance

Parameter	Specification
Safety and design standards	UL8750 (cover identifies Type HL for this Blank/DA2 version); CSA C22.2 No. 250.13-12; ENEC BS EN/EN61347-1, BS EN/EN61347-2-13 and BS EN/EN62384, independent control gear; IP67; EAC TP TC 004; GB/T19510.1 and GB/T19510.213.

Dimensions and installation

Parameter	Specification
Dimensions	171 × 63 × 37.5 mm (L × W × H); plastic housing.
Lead connections	Input: AC/L brown, AC/N blue. LED output: +V red, −V black. Control: DA+ purple, DA− pink.
Cable specification	Input: SJOW 17 AWG × 2C & H05RN-F 1.0 mm²; LED output: the same cable designation. Control: UL2464 18 AWG × 2C. Lead runs: 300 ±20 mm; refer to the mechanical drawing for breakout lengths.
Mounting	Use the model-specific drawing; 4.5 mm mounting holes. Maintain recommended horizontal mounting and keep the marked Tc point below the case-temperature limit.
Ingress protection	Fully encapsulated IP67, for dry, damp or wet locations subject to the installation instructions. Suitable indoors or outdoors without direct sunlight; do not immerse or operate the product in water. Seal system interconnections and any waterproof connector against water ingress.
Installation	Disconnect the supply before installation or maintenance and prevent inadvertent reconnection. Keep ventilation clear, do not stack objects on the unit, and leave 10–15 cm clearance when the adjacent device is a heat source. Approved primary/secondary cables must carry at least the unit’s rated current. Nonstandard mounting or high ambient temperature requires derating. Confirm compatibility with this DALI-2 interface. The catalog’s general installation note cites 0.15 mA per PWM driver; this is not a complete DALI bus/controller sizing specification. Follow the dedicated interface wiring and controller requirements. Insulate system interconnections and enclose single-insulated wires; do not dismantle the driver. Damaged external cables must be replaced by the manufacturer, its service agent or an equally qualified person.
Weight	770 g; catalog packing reference per unit (0.77 kg × 1000), not a measured net or shipping parcel weight.
Service-life reference	Typical lifetime >50,000 hours when the marked Tc/TMP point is about +75°C or below. Manufacturer catalog warranty: 5 years, subject to MEAN WELL’s warranty statement; not an additional store promise.

Unless stated otherwise, catalog parameters are measured at 230 VAC input, rated current and +25°C ambient. Typical figures and load curves apply only to their stated conditions. Read the linked drawings and installation instructions before system design.
