More power. More flexibility. Built for demanding LED applications.
When your LED installation needs serious power without sacrificing reliability, the MEAN WELL HLG-320H is ready to deliver. With up to 320W of output power, dual-mode constant voltage and constant current operation, and a rugged fanless design, it’s built to handle demanding indoor and outdoor lighting applications.
With output options from 12V to 54V, flexible dimming options, IP65/IP67 protection and a wide operating temperature range, the HLG-320H gives you the power and flexibility to build lighting systems that perform reliably — even in challenging environments.
Need more headroom for your LED installation? The HLG-320H delivers up to 320W, with rated output voltages ranging from 12V to 54V.
Its dual-mode design allows it to operate in either constant current mode for direct LED driving or constant voltage mode, giving you greater flexibility when designing your lighting system.
The HLG-320H is designed to keep performing when conditions get demanding.
Its rugged metal housing, IP67/IP65 protection, and fanless construction make it suitable for both indoor and outdoor installations. It can operate with a case temperature from -40°C to +90°C under free-air convection, helping it handle challenging operating environments.
Want more control over your lighting? Selected HLG-320H versions offer 3-in-1 dimming, supporting:
- 1–10V DC
- 10V PWM
- Resistance
The constant-current output level can also be adjusted through these dimming methods, while selected versions feature built-in potentiometers for adjusting output voltage and current.
The HLG-320H combines high output power with impressive efficiency, reaching up to 94% efficiency in the specified operating conditions.
And because there's no fan inside, there's no fan noise or moving cooling parts to worry about. Heat is managed through the driver's rugged design and free-air convection.
The HLG-320H comes equipped with built-in protection features designed to help safeguard both the driver and connected LED system.
Protection includes:
- Over-current protection
- Over-voltage protection
- Over-temperature protection
- Short-circuit protection
Short-circuit protection operates in hiccup mode and automatically recovers once the fault condition is removed, while the over-current, over-voltage and over-temperature protections provide additional safeguards for the system.
The HLG-320H accepts a wide 90–305VAC input range (127–431VDC), making it suitable for a broad range of mains supplies.
It also incorporates active power-factor correction, with a typical PF of ≥0.95 at 230VAC at full load and ≥0.94 at 277VAC.
