Product Overview

The MEAN WELL ELG-150U series is a 150W AC-to-DC LED driver family designed for both constant-current (CC) and constant-voltage (CV) operation. It accepts universal 100~305VAC input (142~431VDC) and offers 24V, 36V, and 48V output options, making it a flexible platform for North American LED lighting systems.

With peak efficiency up to 90%, the ELG-150U uses a fanless design and operates at a case temperature of -40C to +85C under natural convection. The metal enclosure is designed to UL8750 Type HL for use in Class I Division 2 hazardous location luminaires, and is listed as a UL Class 2 power supply for simplified wiring and installation.

Three function versions are available: Blank (fixed output), A (internal potentiometer adjustment), and B (3-in-1 dimming with dim-to-off). This lets lighting designers match the exact control strategy of each luminaire without changing the driver platform.

Standard protection includes over-current CC limiting, short-circuit hiccup, over-voltage restart, and over-temperature restart. The driver complies with UL safety and FCC Part 15 Class A emission requirements, and is backed by a 5-year warranty.

Frequently Asked Questions

What is the difference between CC mode and CV mode on ELG-150U?

In CC mode the driver maintains a constant current output while the voltage automatically adjusts within the model-specific CC range to match the LED string forward voltage. In CV mode the driver maintains a stable output voltage with a current limit, suitable for LED strips, modules, or loads that expect a fixed voltage bus.

What does UL Class 2 mean for ELG-150U?

UL Class 2 means the driver has limited output power and is considered safe from a fire and electric shock perspective without requiring additional over-current protection in the field. This simplifies wiring and reduces installation cost in North American applications.

Which version type should I choose?

Blank for simple fixed-output luminaires. A-Type for fixtures needing current/voltage tuning via internal pot. B-Type for smart lighting with 0-10V/PWM/resistor dimming, including dim-to-off capability.

Does ELG-150U support DALI dimming?

No, the ELG-150U series offers Blank, A, and B versions only. B-Type provides 3-in-1 dimming (0-10V, PWM, resistor) with dim-to-off, but does not support DALI. For DALI control, consider the standard ELG-150/200/240 series DA-Type versions.
