Mean Well HLG-320H-30B Power Supply 320W 30V- Dimmable

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.

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.

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.

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.

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.

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.
