Frequently Asked Questions

Can I use the HLG-40H-48AB to power 48V LED strip lighting in covered outdoor areas?

Yes. The HLG-40H-48AB outputs 48V at up to 0.84A (40W) and carries an IP65 water-resistant rating, making it suitable for covered patios, canopies, and soffits where splashing water or dust may be present. For fully rain-exposed locations, consider the IP67-rated HLG-40H-48B instead.

Is the HLG-40H-48AB a good driver for small 48V LED signage projects?

Yes. With 40W at 48V, it can power compact 48V LED sign modules or channel letters with low total wattage. The built-in dimming input lets you adjust brightness for day/night cycles, and the adjustable output helps fine-tune voltage to match specific module requirements.

Can I dim the HLG-40H-48AB using a 1-10V or PWM signal?

Yes. The AB suffix means it supports both output voltage/current adjustment via built-in potentiometer and external dimming via 1-10V, PWM, or resistance input. This makes it well suited for applications where you need both precise output trimming and remote brightness control.

How many meters of 48V LED strip can the HLG-40H-48AB drive?

Divide 40W by your strip's power per meter. For example, a 48V strip rated at 8W/m would allow up to 5 meters (40W / 8W per meter = 5m). Always check your strip's rated power per meter and keep the total load at or below 40W.

What is the difference between the HLG-40H-48, 48A, 48AB, and 48B models?

All four share the same 40W / 48V / 0.84A core specs. The base HLG-40H-48 has no adjustment or dimming and is IP67 waterproof. The -48A adds output voltage/current adjustment via potentiometer (IP65). The -48AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -48B adds dimming input only and retains IP67.

Is the HLG-40H-48AB suitable for installation in a dusty warehouse or workshop?

Yes. Its IP65 rating provides complete protection against dust ingress and low-pressure water jets. The aluminium casing and -40°C to +80°C operating temperature range also make it durable in environments with temperature fluctuations and airborne particulates.
