Mean Well HLG-320H Model Encoding
The model number identifies the series, rated wattage, output voltage, and function type. For example, HLG-320H-24A identifies a 24V model with adjustable output, while HLG-320H-24B identifies a 24V model with 3-in-1 dimming. The fixed-output configuration uses no function suffix, such as HLG-320H-24. The terminal-block version uses the C suffix, such as HLG-320H-24C.
Why Choose the Mean Well HLG-320H Series?
The Mean Well HLG-320H Series delivers high-efficiency power conversion, flexible output configurations, and durable construction for demanding LED lighting systems. With active PFC, fanless operation, IP65/IP67 options, and a 7-year warranty, it provides a reliable power solution for commercial, industrial, and outdoor lighting applications.
