Description

XLG-240-L-A LED driver

MEAN WELL XLG-240-L-A is a 239.4 W constant-power LED driver with a 700 mA factory current setting and a 178–342 V constant-current operating region. This version provides potentiometer current adjustment. The LED load must fit the published I–V boundary and power limit; the full voltage/current rectangle is not usable.

Output and model selection

Rated output	239.4 W; factory current 700 mA.
Constant-current voltage region	178–342 V, subject to the I–V operating envelope.
Full-power current range	700–1050 mA. Rated power requires a compatible LED forward voltage within the operating boundary.
Current adjustment	350–1050 mA via the built-in potentiometer; available for this A version. Set current to suit the LED load and respect all power/protection limits.
I–V boundary points	Catalog boundary vertices, in mA / V: 350 / 342; 700 / 342; 1050 / 228; 1050 / 178; 700 / 178. These identify the operating area, not simultaneous maximum output values or an overload rating.
Open-circuit voltage	370 V maximum.
Current ripple	5% under the catalog condition “Load ≥50% rated voltage”.
Current tolerance	±4%.

Input and performance

Input voltage	100–305 VAC / 142–431 VDC. Respect the low-input-voltage derating curve; the DC range is an input rating, not an LED output range.
Input frequency	47–63 Hz.
Input/load derating	At 60 Hz: 80% load at 100 VAC, increasing to 100% at 110 VAC; 100% from 110 to 305 VAC.
Power factor	Active PFC; PF ≥0.97 at 115 VAC, ≥0.95 at 230 VAC and ≥0.92 at 277 VAC, at full load.
Total harmonic distortion	<10% at load ≥50% on 115/230 VAC; <10% at load ≥75% on 277 VAC.
Efficiency	93% typical, under the catalog specification conditions.
AC input current	2.7 A at 115 VAC; 1.3 A at 230 VAC; 1.1 A at 277 VAC.
Inrush current	Cold start 85 A at 230 VAC; pulse width 500 µs measured at 50% Ipeak, per NEMA 410.
Circuit-breaker reference	Maximum 2 B-type / 4 C-type units on a 16 A breaker at 230 VAC, as listed in this model’s catalog. Verify the actual breaker and installation conditions.
Leakage current	<0.75 mA at 277 VAC.
Setup time	500 ms at 230 VAC; 1200 ms at 115 VAC. The catalog measures the first cold start and states that repeated ON/OFF operation may increase setup time.

Control and operating limits

Control interface	Potentiometer current adjustment. No DIM lead or remote 3-in-1 dimming function is specified for this complete suffix.

Protection and recovery

Short-circuit protection	Hiccup mode or constant-current limiting; automatic recovery after the fault is removed.
Overvoltage protection	380–450 V; output shutdown, re-power to recover.
Overtemperature protection	Output shutdown; re-power to recover.
Adjustment and switching cautions	The catalog states that adjustment above 110% of rated current enters protection. Apply this condition together with the stated I–V envelope and adjustment table; do not treat the wide adjustment range as an unconditional overload allowance. AC ON/OFF operation at low LED Vf and low load can produce output-current overshoot.
Rapid AC switching	Rapid AC switching can trigger the PWM control IC protection mechanism; follow the catalog operating conditions.

Cooling, environment and reliability

Case-temperature rating	Working Tcase -40 to +90°C; separately listed maximum case temperature +90°C. A case-temperature rating is not an unrestricted ambient-temperature rating.
Ambient/load derating	Recommended horizontal mounting: 230 VAC: 100% through +50°C, then 60% at +60°C. 110 VAC: 100% through +40°C, then 60% at +50°C. Meet the ambient-load curve and case-temperature limits together.
Case/load curve	For horizontal mounting, the case-load graph remains at 100% through +90°C and ends there. Observe the working-case rating above as well.
Low-temperature startup	The −40 to −30°C portion of the ambient curve applies at 230 VAC only. The soft-start reference is full load at −30°C and 110 VAC.
Cooling and altitude	Fanless free-air convection. Nonstandard mounting requires appropriate derating. Above 2000 m, reduce the allowed ambient temperature by 3.5°C per additional 1000 m.
Working humidity	20–95% RH, non-condensing.
Storage conditions	-40 to +80°C; 10–95% RH, non-condensing.
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.
Performance-plot conditions	PF, THD and efficiency plots use Tcase 75°C. The L-type examples do not replace the tabulated efficiency for this output version.
Lifetime reference	Typical operating life >50,000 hours with the marked tc/TMP point about 75°C or less. This is an operating-life reference, separate from warranty.
MTBF	2496.2 K hours, Telcordia SR-332; 219.8 K hours, MIL-HDBK-217F at 25°C; catalog minimum estimates.

Warranty	Manufacturer catalog: 5-year warranty, subject to MEAN WELL’s warranty statement and applicable conditions.

Installation and selection

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.
ErP switching requirement	Use this LED driver behind a switch; it must not remain permanently connected to the mains for the catalog ErP lighting-fixture application.
Selection and applications	Select the complete input/output/control suffix for the LED load. The family applications include street, architectural, bay, flood and horticultural lighting, subject to the exact electrical envelope, thermal design and installation limits.
Configuration and accessories	External controllers, connection hardware and any optional surge configuration must be selected for the actual model. No dedicated separately ordered accessory is included by this product description; confirm the manufacturer’s complete ordering specification for a modified configuration.
