Frequently Asked Questions
Can I use the HLG-320H-48AB to power dimmable 48V LED strip installations?
Yes. The HLG-320H-48AB delivers 48V at up to 6.7A (320W) and accepts 1-10V or PWM dimming signals. This makes it ideal for 48V LED strip installations where you need external brightness control, such as architectural accent lighting or daylight-responsive systems.
Is the HLG-320H-48AB suitable for smart building 48V LED lighting with automated dimming?
Yes. The AB suffix means this model has both output adjustment via potentiometer and a 1-10V/PWM dimming input. You can integrate it with building management systems, occupancy sensors, or daylight harvesters for automated brightness control at up to 320W.
Can the HLG-320H-48AB drive 48V LED fixtures in a retail display setting?
Yes. At 320W and 48V, it can power extended runs of retail display lighting. The dimming input allows scene-setting for different merchandise presentations, and the adjustable output lets you trim voltage to match the exact fixture requirements for uniform brightness.
Can I use the HLG-320H-48AB for 48V horticultural LED panels with light-schedule control?
Yes. The 320W output handles high-power grow panels at 48V, and the dimming input can be driven by a grow-light controller to adjust intensity for different growth stages. The adjustable output also lets you fine-tune voltage to the panel's optimal operating point.
How many meters of 48V LED strip can the HLG-320H-48AB power?
Divide 320W by your strip's rated power per meter. For example, a strip rated at 12W/m would allow about 26.6 meters (320W / 12W per meter). Always check your strip's rated power per meter and keep the total load at or below 320W for reliable operation.
Is the HLG-320H-48AB weatherproof enough for a covered outdoor patio installation?
Yes. Its IP65 rating protects against low-pressure water jets and dust, which is sufficient for covered patios, pergolas, or soffit-mounted applications. For fully exposed rain installations, the IP67-rated HLG-320H-48B with dimming would be a better choice.
