Product Overview

The MEAN WELL XLG-50-DA2 series is a 50W AC-to-DC constant-power LED driver family with DALI-2 digital dimming, IP67 protection, Class 2 power rating, and Type HL certification for Class I, Division 2 hazardous location lighting (H-Type only). It is designed for LED street lighting, architectural lighting, bay lighting, flood lighting, stage lighting, sports lighting, and industrial lighting.

It accepts universal 90~305VAC input (127~431VDC) and provides a constant-power 50W output. Two output types are available: L-Type with default current 700mA and CC region 60~142V, and H-Type with default current 1050mA and CC region 27~56V. Output current can be adjusted via an internal potentiometer (300~700mA for L-Type, 500~1400mA for H-Type). With peak efficiency up to 90%, the driver uses a fanless design and operates at case temperatures from -40C to +85C under free air convection.

The metal enclosure carries an IP67 rating for both indoor and outdoor use. All DA2 versions support IEC 62386 DALI-2 DT6 digital dimming down to approximately 8% minimum brightness, with isolated dimming circuitry. India versions (XLG-50I-L-DA2 / XLG-50I-H-DA2) add input over-voltage protection at 320~370VAC and comply with IS 15885. No-load / standby power consumption is below 0.5W.

Protection includes short-circuit (hiccup or constant current limiting), over-temperature (de-rate to 75% then 50%, auto-recovery), and input over-voltage (320~370VAC on I-Type only, auto-recovery; withstand 440VAC for 48h). The driver complies with global lighting safety and EMC standards including UL8750 Type HL, CSA, ENEC, AS/NZS, BS EN/EN, GB/T, EAC, and IS 15885 (I-Type only), and is backed by a 5-year warranty. Note: a switch must be installed between the mains and the LED driver to meet the latest ErP regulations.

Frequently Asked Questions

What is the difference between L-Type and H-Type in XLG-50-DA2?

L-Type is optimized for high-voltage LED strings with a default current of 700mA and CC region of 60~142V. H-Type is optimized for lower-voltage, higher-current LED loads with a default current of 1050mA and CC region of 27~56V. Both deliver 50W constant power and support DALI-2 dimming.

Does XLG-50-DA2 support DALI-2 dimming?

Yes, all DA2 versions comply with IEC 62386-101, 102, 207, 251 and support Device Type 6 (DT6) DALI-2 digital dimming. The dimming circuit is isolated from the output. Minimum dimming level is approximately 8%.

What is the difference between standard and I-Type versions?

Standard L-DA2 and H-DA2 are global versions. I-L-DA2 and I-H-DA2 are India-market versions that add input over-voltage protection (320~370VAC) and IS 15885 certification. I-Type has slightly higher no-load power (<0.75W).

Is XLG-50-DA2 a constant-voltage driver?

No. XLG-50-DA2 is a constant-power LED driver that operates in constant-current mode within the stated CC region. It is designed for direct LED string connection, not for LED modules that require a constant-voltage supply.

What does Class 2 and Type HL certification mean?

Class 2 means the output is limited to a safe power level, simplifying wiring requirements. Type HL means the driver is UL8750 listed for use in Class I, Division 2 hazardous location lighting fixtures when installed per manufacturer instructions. Type HL applies to H-Type only.
