Frequently Asked Questions
Can I use the HLG-320H-48B for outdoor 48V LED strip lighting that needs dimming?
Yes. The HLG-320H-48B delivers 48V at up to 6.7A (320W) with an IP67 waterproof rating and a built-in dimming input. It can be exposed to rain, hose-down, or temporary submersion while still offering 1-10V/PWM dimming control for brightness adjustment.
Is the HLG-320H-48B a good fit for dimmable 48V LED facade or building-perimeter lighting?
Yes. With 320W at 48V and IP67 waterproofing, it handles fully exposed facade installations. The dimming input lets you create lighting scenes or reduce brightness overnight. The wide 90-305VAC input accommodates commercial mains supplies globally.
Can I use the HLG-320H-48B to power dimmable 48V LED landscape path lights?
Yes. At 320W it can drive multiple 48V landscape fixtures from a single driver, and the dimming input allows time-based brightness reduction for energy savings. The IP67 rating means the driver can be placed in a ground-level vault or directly in landscaped areas.
How many meters of 48V LED strip can the HLG-320H-48B support?
That depends on the strip's rated power per meter. The HLG-320H-48B supplies up to 320W at 48V. For instance, if your strip draws 15W/m, you could run about 21.3 meters (320W / 15W per meter). Check your strip's rated power per meter and keep total load at or below 320W.
Can the HLG-320H-48B be installed in a location prone to flooding or standing water?
Yes. Its IP67 rating means the enclosure withstands temporary submersion in up to 1 meter of water. This makes it suitable for light wells, storm-prone outdoor installations, and areas where occasional standing water may occur.
What are the differences between the HLG-320H-48, 48A, 48AB, and 48B models?
All four share the same 320W / 48V / 6.7A core specs. The base HLG-320H-48 has no output adjustment or dimming and is IP67 waterproof. The -48A adds a built-in potentiometer for output adjustment (IP65). The -48AB adds both adjustment and 1-10V/PWM dimming (IP65). The -48B provides dimming input only and retains the IP67 waterproof rating.
