Frequently Asked Questions

Can I use the HLG-100H-48AB with a dimming controller for 48V LED office lighting?

Yes. The HLG-100H-48AB supports 1-10V, PWM, and resistance dimming signals, making it compatible with building management systems and standalone dimming controllers. The adjustable output also lets you fine-tune the baseline brightness for 48V LED fixtures up to 100W.

Is the HLG-100H-48AB suitable for dimmable 48V LED display case or museum lighting?

It is a strong choice where precise brightness control matters. The built-in potentiometer sets the output operating point, while the dimming input enables real-time brightness adjustment to highlight exhibits or merchandise. Total LED load must stay at or below 100W at 48V.

Can I power a dimmable 48V LED video wall backlight with the HLG-100H-48AB?

Yes, provided the backlight array draws no more than 100W. The HLG-100H-48AB delivers 48V at up to 2A with both adjustable output and dimming capability. The dimming input allows synchronizing brightness with video content or ambient light levels.

How many meters of 48V LED strip can the HLG-100H-48AB power?

The maximum strip length depends on the strip's rated wattage per meter, not the dimming level. With 100W available at 48V, a strip rated at 6W/m allows approximately 16.6 meters (100W / 6W per meter). Always verify your strip's rated power per meter and stay within 100W total.

Can the HLG-100H-48AB be used in a damp indoor environment like a natatorium or spa?

The IP65 rating protects against dust and low-pressure water spray, which is generally sufficient for damp indoor spaces where the driver is not directly submerged. Ensure it is mounted away from direct water splash zones. For wet locations with submersion risk, the IP67-rated HLG-100H-48B offers better protection.

How does the HLG-100H-48AB differ from the 48A and 48B models?

The -48AB combines both adjustable output (potentiometer) and dimming input (1-10V/PWM/resistance) at IP65 water-resistant. The -48A has adjustable output only without dimming at IP65. The -48B has dimming only without potentiometer adjustment at IP67 waterproof. All three share the same 100W, 48V, 2A core specs.
