Frequently Asked Questions

Can I use the HLG-150H-48AB with a building automation system to dim 48V LED fixtures?

Yes. The HLG-150H-48AB accepts 1-10V and PWM dimming signals, making it compatible with most building management and automation systems. The built-in potentiometer also allows manual fine-tuning of the maximum output level independently from the dimming control.

Is the HLG-150H-48AB a good driver for dimmable 48V LED office or retail lighting?

Yes. With 150W at 48V, adjustable output, and dimming input, it is well suited for commercial environments where lighting levels need to change throughout the day. The 48V output also permits longer cable runs with less voltage drop compared to 24V systems, which is an advantage in large retail or open-plan office layouts.

Can the HLG-150H-48AB power a 48V LED cove lighting system with smooth dimming?

Yes. The combination of adjustable output and 1-10V/PWM dimming makes it ideal for architectural cove lighting where precise brightness control matters. You can set the potentiometer to match your LED strip's optimal drive level, then use the dimming input for day-to-day brightness changes.

How many meters of 48V LED strip can the HLG-150H-48AB drive?

Divide 150W by your strip's wattage per meter. A 48V strip rated at 12W/m could run up to 12.5 meters (150W / 12W per meter = 12.5m). Check your strip's rated power per meter and keep the total load at or below 150W for reliable dimming performance.

Can the HLG-150H-48AB be used in a humid indoor space like a pool area or spa room?

Its IP65 rating protects against low-pressure water jets and dust, which is generally adequate for humid indoor environments like pool equipment rooms or spa areas where the driver is not directly submerged. For locations with potential water immersion, the IP67-rated HLG-150H-48B with dimming would be a better choice.
