Output and selection

Model and function	Standard version; A provides output-current adjustment through the built-in potentiometer.
Rated output power	50 W. Rated at 100–305 VAC; derate below 100 VAC.
Output current	1 A default. 0.53–2.1 A via the built-in current adjustment potentiometer. This range must be combined with the I–V operating envelope.
Constant-current voltage region	22–54 V. Keep voltage × current within the 50 W rating and the shaded I–V region. The full current/voltage rectangle is not usable.
Open-circuit voltage	57 V maximum.
Output current ripple	5.0% maximum at rated current.
I–V selection boundary	The published envelope includes 530 mA/54 V, 1050 mA/22 V and 2100 mA/22 V boundary points. At low current the minimum usable voltage rises; choose within the shaded area and the 50 W rating.
Startup	Setup 500 ms; rise 100 ms at 115 VAC / 230 VAC. Setup is measured at first cold start; repeated switching can increase it.

Input and performance

Input supply	90–305 VAC; 127–431 VDC. AC frequency 47–63 Hz. Active PFC.
Input derating	The 60 Hz static curve permits 90% load at 90 VAC, rising to 100% at 100 VAC and remaining at 100% through 305 VAC. Thermal limits apply simultaneously.
Power factor	At full load: PF ≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC.
Total harmonic distortion	THD <10% at load ≥50% for 115/230 VAC, or load ≥75% for 277 VAC.
Input current	0.57 A / 115 VAC; 0.29 A / 230 VAC; 0.24 A / 277 VAC.
Inrush current	Typical cold start 50 A at 230 VAC; width 350 µs at 50% peak, per NEMA 410.
16 A circuit breaker loading	5 units on type B and 8 on type C at 230 VAC, as listed in this datasheet.
Leakage current	<0.75 mA at 277 VAC.
Typical efficiency	90% at the specification reference conditions: 230 VAC input, rated current and 25°C ambient.
No-load / standby consumption	No-load consumption <0.5 W for A type.

Protection

Short-circuit protection	Constant-current limiting; automatically recovers after the fault is removed.
Overpower protection	110–150% overpower protection; automatically recovers after the fault is removed.
Overtemperature protection	Hiccup operation; automatically recovers after the fault is removed.

Operating conditions

Case temperature	Tcase −40 to +90°C; maximum case temperature +90°C. Case temperature and ambient temperature are different limits.
Ambient derating	Horizontal mounting: at 230 VAC, full load through 60°C ambient, reducing to 60% at 70°C; at 100 VAC, full load through 50°C, reducing to 60% at 60°C. The cold region from −40 to −25°C is marked for 230 VAC input only. Keep the case within its stated limit.
Cooling and altitude	Natural air convection. Above 2000 m altitude, reduce permitted ambient temperature by 3.5°C per additional 1000 m for this fanless model.
Humidity and storage	Working humidity 20–95% RH. Storage temperature −40 to +80°C.
Temperature coefficient	±0.03%/°C over 0–60°C.
Vibration	10–500 Hz, 5 G, 12 minutes per cycle; 72 minutes along each X, Y and Z axis.
Lifetime and warranty	Catalog typical life expectancy >50,000 hours with the marked tc point about 75°C or lower. Five-year manufacturer warranty, subject to its warranty terms. Lifetime decreases as case temperature increases.
Reliability	3931.6 K hours minimum by Telcordia SR-332; 394.6 K hours minimum by MIL-HDBK-217F at 25°C. MTBF is not a service-life guarantee.

Control and adjustment

Current setting	Set the rated current with the built-in Io ADJ potentiometer; preserve the adjustment seal and the published I–V and temperature limits.

Safety and EMC

Construction and classification	Metal housing, IP67, active PFC and catalog Class 2 power-unit design. The catalog describes metal housing with functional ground. Follow the fitted earth lead and model wiring requirements.
Applicable safety standards	UL8750 (Type HL); CSA C22.2 No.250.13-12. ENEC AS/NZS IEC / BS EN/EN61347-1 and BS EN/EN61347-2-13 independent; BS EN/EN62384; GB/T19510.1 and GB/T19510.213; J61347-1(H29) and J61347-2-13(H29); EAC TP TC 004; KC61347-1 and KC61347-2-13. NOM-058-SCFI-2017 is listed; consult MEAN WELL for the required Mexico certificate.
Certification applicability	Check the exact product markings and destination requirements. Units sourced from the Americas may not carry CCC, PSE, BIS or KC logos.
Electrical insulation	Withstand: input–output 3.75 kVAC; input–FG 2.0 kVAC; output–FG 1.5 kVAC. Insulation resistance for these pairs: 100 MΩ at 500 VDC, 25°C and 70% RH.

Final-equipment compliance	Requalify EMC on the complete installation. For the catalog ErP lighting-fixture condition, install behind a switch rather than permanently connecting to the mains.
Type HL application	The catalog identifies Type HL for Class I, Division 2 hazardous (classified) locations; built-in installation must be considered to comply with the Type HL application. This component classification does not approve the complete luminaire.

Dimensions and installation

Size and mounting	105 × 63 × 30 mm (L × W × H), case 268A; drawing tolerance ±1 mm. Four Ø4.5 mm mounting holes with 99 mm longitudinal spacing and 40 mm transverse spacing. Recommended mounting is horizontal on a flat surface.
Power leads	AC/L brown, AC/N blue, earth green/yellow; output V+ red and V− black. Input cable: SJOW 17 AWG × 3 cores / H05RN-F 3 × 1.0 mm²; output: SJOW 17 AWG × 2 cores / 1.0 mm². AC and output lead lengths 300±20 mm.
Case-temperature measurement	Use the tc point marked in the mechanical drawing. Its location is dimensioned 61.3 mm and 31.6 mm from the shown drawing references; do not substitute ambient temperature for tc.
Catalog packing reference per unit	0.41 kg = 410 g for this A type. This is the catalog per-unit packing reference, not a measured net weight or an entire shipping-carton weight.
Accessories and selection	Select installation hardware and any dimming controller for the actual model, load and environment. The inspected series sheets do not specify a dedicated MEAN WELL accessory order code for this model. IP67 is subject to the installation instructions and does not authorize immersion.

Installation manual requirements

Installation safety	Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting	Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection	Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system. Connect a fitted FG lead to protective earth according to the model wiring; the manual exempts only units marked Class II and ungrounded.
Environmental and load limits	Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support	If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Adjustable-unit weather protection	This IP67 model has a built-in adjustment function. Install it indoors or in a location sheltered from rain outdoors, as required by the installation manual. IP67 does not permit immersion.
