Description

XLG-240-48-ABV LED driver

MEAN WELL XLG-240-48-ABV is a 240 W constant-voltage LED driver rated at 48 V and 5 A. Its built-in potentiometer adjusts the voltage from 43.2 to 52.8 V, while the isolated 3-in-1 interface dims the output voltage. Keep voltage × current within the 240 W maximum throughout adjustment.

Output and model selection

Rated output	48 V DC; 5 A; 240 W maximum.
Built-in voltage adjustment	43.2–52.8 V through the potentiometer. At an increased voltage, reduce current as necessary to stay within the rated power.
Ripple and noise	250 mVp-p maximum.
Voltage tolerance	±2%.
Dimming tolerance	±4%.
Line / load regulation	±0.5% / ±0.5%.

Input and performance

Input voltage	110–305 VAC / 156–431 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: 100% load from 110 to 305 VAC; operation below the 110 VAC minimum is not authorized by the ABV input specification.
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	91% 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.
Standby consumption	<0.5 W with dimming OFF, for this ABV standard version.

Control and operating limits

Control function	Isolated 3-in-1 output-voltage dimming, using 0–10 V DC, a 10 V PWM signal at 100 Hz–3 kHz, or resistance between DIM+ and DIM−. This changes the output voltage level, not the output-current setpoint.
Control wiring	DIM+ = purple; DIM− = pink. Do not connect DIM− to output Vo−. Connect the LED load directly; additional drivers are not suitable for this dimming arrangement.
Dimming source and resistance	Typical dimming source current 100 µA. For N drivers in parallel, the graph uses 10 kΩ/N at 10% control and 100 kΩ/N at 100% control; output voltage follows the voltage-dimming curve rather than the CC current chart.
Voltage dimming limits	The nominal dimming range starts at about 50% output voltage and extends to 100%. Output is not defined below the minimum operating level; the operating note separately permits 0% when the DIM input is about 0 Ω, 0 V DC or 0% 10 V PWM duty. Confirm the exact low-end response for the application instead of extrapolating the simplified I–V sketch.
Preset and power limit	The built-in potentiometer adjusts the nominal 48 V output to 43.2–52.8 V. Both the current limit and 240 W total power limit remain applicable throughout voltage adjustment and dimming.

Protection and recovery

Short-circuit protection	Hiccup mode or constant-current limiting; automatic recovery after the fault is removed.
Overload protection	105–135%; hiccup mode or constant-current limiting with automatic recovery after the fault is removed.
Overvoltage protection	54–60 V; output shutdown, re-power to recover.
Overtemperature protection	Output shutdown; re-power to recover. If secondary OTP fails, a primary OTP also shuts down the output and requires re-powering.

Cooling, environment and reliability

Case-temperature rating	Working Tcase -20 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 limit	The ABV specification starts at −20°C. The colder −40°C family curve is not an ABV operating permission.
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	-20 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. Use the applicable operating envelope and the ABV specification rather than treating the family performance example as a separate ABV guarantee.
Lifetime reference	Typical operating life >50,000 hours with the marked tc/TMP point about 70°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.

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.
Dimming-controller installation	Verify that the controller can drive the actual interface and number of units. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), use SELV controllers/networks; contact MEAN WELL for guidance before using FELV control. Follow this exact model’s dimming method and wiring.
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.
