Industrial LED Driver

The Mean Well HLG-150H-48 is a 150W single-output switching power supply delivering 48V at 3.2A. It is designed for engineers and installers who need a reliable constant-voltage source for LED lighting systems in commercial or municipal projects. The unit accepts a universal AC input up to 305VAC for worldwide deployment.

Sustained Load Behaviour

High efficiency up to 94% reduces heat generation during continuous operation. Cooling relies on free air convection without moving parts, maintaining stable output over long duty cycles. Built-in active PFC and protections against short circuit, over current, over voltage and over temperature protect the driver under sustained stress.

Decisive Specification

The IP67 and IP65 ratings certify the enclosure against dust and water ingress for outdoor or harsh indoor installations. Output current is adjustable via internal potentiometer to match specific LED array requirements. This driver meets 4kV surge immunity per IEC61000-4-5 for resilient field deployment.

Questions about this item

How much heat does the HLG-150H-48 generate when running continuously at 150W load?

With up to 94% efficiency only a small fraction of the 150W becomes heat, and the fanless convection design dissipates it silently.

What wiring must I already have to connect this 48V 3.2A supply?

You need an AC cable rated for up to 305VAC input and DC cables sized for 48V at 3.2A to reach your LED load.

Can I dim this unit with the 1–10V controller I use on older Mean Well drivers?

Yes, the B-Type version provides a built-in 3-in-1 dimming interface that accepts 1–10VDC, PWM signals or resistance control.
