Product Overview

The MEAN WELL XLG-25 series is a 25W AC-to-DC constant-power LED driver family with IP67 protection, Class 2 power rating, and Type HL certification for Class I, Division 2 hazardous location lighting. It is designed for LED street lighting, architectural lighting, bay lighting, flood lighting, and industrial lighting.

It accepts universal 90~305VAC input (127~431VDC) and provides a constant-power 25W output with a default current of 700mA and an adjustable current range of 0.25~1.05A via an internal potentiometer. The constant-current region is 22~54V with a maximum open-circuit voltage of 57V. With peak efficiency up to 88%, 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. Four function versions are available: A (current adjustable), AB (current adjustable + 3-in-1 dimming), I-A (India version with input OVP), and I-AB (India version with dimming + input OVP). The AB-type dimming circuit is galvanically isolated from the output and supports 0~10Vdc / 10V PWM / resistor dimming down to approximately 0%. No-load power consumption is below 0.5W on A-Type and standby power below 0.5W on AB-Type.

Protection includes over-power (110-150%), short-circuit (constant current limiting), and over-temperature (hiccup mode), all with automatic recovery after fault removal. The I-Type adds input over-voltage protection at 320~370VAC. The driver complies with global lighting safety and EMC standards including UL8750 Type HL, CSA, ENEC, AS/NZS, BS EN/EN, GB/T, JIS, EAC, KC, 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.

Key Features

Constant Power Output -- Flexible LED Drive
XLG-25 is a 25W constant-power LED driver. Output current can be adjusted from 0.25A to 1.05A via an internal potentiometer, supporting LED strings from 22V up to 54V with a maximum open-circuit voltage of 57V.

4 Version Types -- A / AB / I-A / I-AB
A-Type provides adjustable current. AB-Type adds isolated 0~10Vdc / 10V PWM / resistor dimming. I-Type variants add input over-voltage protection for India and other markets requiring 320~370VAC OVP.

Class 2 + Type HL + IP67
Class 2 power limits simplify installation wiring. UL8750 Type HL certification supports hazardous location lighting. Sealed metal housing supports indoor and outdoor use.

Active PFC + Global Certifications
PF>=0.97 at 115V and THD<10% keep installations compliant. UL/CSA/ENEC/AS/NZS/GB/JIS/EAC/KC/NOM certifications enable worldwide deployment; IS 15885 for India on I-Type.

High Surge & Wide Temperature Range
Fanless operation from Tcase -40C to +85C. Passes 5G vibration and 4KV line-to-earth / 2KV line-to-line surge immunity for harsh outdoor and industrial environments.

5-Year Warranty + Ultra-Low Standby
Backed by a 5-year warranty. No-load/standby power is below 0.5W to meet modern ErP requirements. Compact 105 x 63 x 30mm metal housing fits tight fixtures.

Frequently Asked Questions

What is constant power mode on XLG-25?

XLG-25 maintains a constant 25W output while the output current and voltage adjust within the operating window. The default current is 700mA and the output voltage range is 22~54V. You can adjust current from 0.25A to 1.05A via the internal potentiometer to match your LED module.

What is the difference between A-Type, AB-Type, I-A and I-AB?

A-Type is the standard adjustable-current version. AB-Type adds 0~10Vdc / 10V PWM / resistor dimming. I-A and I-AB are India-market versions that add input over-voltage protection (320~370VAC) while keeping the same output features as A and AB respectively. I-Type has a slightly higher no-load power (<0.75W).

Is XLG-25 a constant-voltage driver?

No. XLG-25 is a constant-power LED driver that operates in constant-current mode within the 22~54V region. It is designed for direct LED string connection, not for LED modules that require a constant-voltage supply.

Which dimming signal does the AB-Type support?

AB-Type supports 3-in-1 dimming: 0~10Vdc analog voltage, 10V PWM signal (100Hz~3kHz), or an external resistor. The DIM- port is isolated from Vo- and must not be connected to Vo-. Output current can be dimmed down to approximately 0%.

What does Class 2 and Type HL 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.
