Frequently Asked Questions
Can I use the HLG-120H-30 to power 30V LED strip lighting outdoors?
Yes. The HLG-120H-30 outputs 30V at up to 4A (120W) with an IP67 waterproof rating, making it suitable for outdoor 30V LED strip installations. The aluminium casing and -40°C to +80°C operating range let it handle rain, snow, and temperature extremes year-round.
Is the HLG-120H-30 appropriate for driving 30V LED modules in outdoor signage?
Yes. At 120W and 30V output with a wide 90-305VAC input, it can power outdoor 30V channel letters, cabinet signs, and illuminated directories. The IP67 waterproof rating means the driver can be mounted near the sign without extra weatherproofing.
Can I use the HLG-120H-30 for 30V commercial or industrial LED panel lighting?
Yes. The 120W capacity at 30V can drive multiple 30V LED panels in parallel, provided their combined load stays within 120W. The constant-current mode with a CC voltage range of 15-30V accommodates panels that may draw slightly below the nominal 30V during startup.
How many meters of 30V LED strip can the HLG-120H-30 power?
That depends on the strip's rated power per meter. The HLG-120H-30 delivers up to 120W at 30V. If your strip draws 15W/m, you could run up to 8 meters (120W / 15W per meter = 8m). Always check your strip's rated power per meter and keep the total load at or below 120W.
Can the HLG-120H-30 be installed in a location subject to hose-down or temporary flooding?
Yes. The IP67 rating means the enclosure is protected against temporary submersion up to 1 meter. It handles hose-down cleaning, heavy rain, and temporary flooding. Combined with its -40°C to +80°C range, it suits industrial wash-down areas and exposed outdoor mounting.
What are the differences between the HLG-120H-30, 30A, 30AB, and 30B variants?
All four share the same 120W / 30V / 4A core specs. The base HLG-120H-30 has fixed output and IP67 waterproof rating. The -30A adds output voltage/current adjustment via built-in potentiometer (IP65). The -30AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -30B offers dimming input only and retains IP67 waterproof rating.
