Frequently Asked Questions

Can I use the HLG-320H-30B for outdoor 30V LED strip installations that need dimming?

Yes. The HLG-320H-30B delivers 320W at 30V with dimming capability and carries an IP67 waterproof rating, making it suitable for fully exposed outdoor LED strip installations. It supports 1-10V, PWM, and resistance dimming signals for smooth brightness control.

Is the HLG-320H-30B a good choice for dimmable 30V LED facade or building lighting?

It is well suited for architectural facade lighting where dimming and weather resistance are both essential. The 320W capacity can drive extensive 30V LED arrays, and the IP67 rating allows mounting in locations exposed to rain, snow, or washdown without an additional enclosure.

Can I power a 30V dimmable LED sign with the HLG-320H-30B?

Yes, provided total power draw stays within 320W. The dimming function lets you reduce brightness for nighttime or ambient conditions, and the IP67 waterproof rating means the driver can be mounted inside or outside the sign cabinet. The wide 90-305VAC input handles different mains voltages globally.

Can the HLG-320H-30B be installed in a wet or underground location?

Yes. Its IP67 waterproof rating protects against dust ingress and temporary submersion up to 1 meter. The sealed aluminium housing and -40°C to +90°C operating temperature range make it suitable for underground vaults, tunnel lighting, or other damp and harsh environments.

How many meters of 30V LED strip can the HLG-320H-30B drive?

The HLG-320H-30B provides 320W at 30V. Divide 320W by your strip's rated wattage per meter. For example, a strip drawing 20W/m would support up to 16 meters (320W / 20W per meter = 16m). Always check your strip's rated power per meter and keep total load at or below 320W.

How does the HLG-320H-30B differ from the HLG-320H-30 and HLG-320H-30A?

All three deliver 320W at 30V and 10.7A. The base HLG-320H-30 has fixed output and IP67. The -30A adds adjustable output via potentiometer but drops to IP65. The -30B (this model) adds dimming capability while keeping the IP67 waterproof rating, but does not include adjustable output.
