Frequently Asked Questions
Can I use the HLG-320H-54AB to power high-output 54V LED fixtures for warehouse or industrial lighting?
Yes. The HLG-320H-54AB delivers 320W at 54V with up to 5.95A, which is well suited for high-bay or industrial 54V LED fixtures. Its built-in adjustment and dimming allow you to tune output to the fixture load and control brightness via 1-10V, PWM, or resistance signals.
Is the HLG-320H-54AB a good choice for dimming outdoor 54V LED floodlights?
Yes. It supports 1-10V, PWM, and resistance dimming inputs, so you can integrate it with common lighting-control systems. The IP65 water-resistant rating handles dust and low-pressure water jets, making it suitable for covered outdoor locations such as canopies or building facades. For fully exposed rain installations, the IP67-rated HLG-320H-54B may be more appropriate.
Can the HLG-320H-54AB drive 54V LED grow lights in a greenhouse?
Yes. At 320W and 54V output, it can power horticultural LED arrays that operate at 54V. The adjustable output lets you fine-tune voltage and current to match the grow-light module, while the dimming input enables day-cycle light scheduling. Its wide -40°C to +90°C operating range accommodates temperature swings in greenhouse environments.
How many meters of 54V LED strip can the HLG-320H-54AB power?
Divide 320W by the strip's rated power per meter. For example, a 54V strip drawing 20W/m could run up to 16 meters (320W / 20W per meter = 16m). Always check your strip's rated power per meter and keep the total load at or below 320W.
Is the HLG-320H-54AB suitable for a covered outdoor parking structure?
Yes. Its IP65 rating protects against dust and low-pressure water jets, which is sufficient for covered or semi-enclosed structures like parking garages, loading docks, and carports. For locations with direct, sustained rain exposure, consider the IP67-rated HLG-320H-54B instead.
What are the differences between the HLG-320H-54, 54A, 54AB, and 54B models?
All four share the same 320W / 54V / 5.95A core specs with a CC voltage range of 27-54V. The base HLG-320H-54 has fixed output and is IP67. The -54A adds output voltage/current adjustment via built-in potentiometer (IP65). The -54AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -54B provides dimming input only and retains IP67.
