Mean Well XLG-320-M-DA2 Power Supply 310.8W 2800mA - DALI2 Dimmable

Yes. The XLG-320-M-DA2 delivers 310.8W at 2800mA constant current with a CC voltage range of 115–230V, making it well suited for powering series strings of high-power LED downlights in commercial installations. The DALI2 interface allows individual dimming control from a building automation system.

Yes. The driver carries an IP67 waterproof rating, so it can be mounted inside outdoor signage enclosures exposed to rain and dust. Its operating temperature range of -40°C to +90°C also covers most outdoor climates.

Yes. With 310.8W of output power and an adjustable current range of 1050–2800mA, this driver can support a series array of high-power LED modules within the 115–230V CC voltage range. The exact number of LEDs in the string depends on each LED's forward voltage.

Yes, the driver is designed specifically for DALI2 dimming systems. It supports a minimum dimming level of 8% and integrates directly with DALI2-compliant controllers for smooth, bus-addressed dimming.

The driver's constant current region spans 115–230V, so the number of LEDs in the string depends on the forward voltage of each individual LED. There is no fixed LED count — select LEDs whose combined forward voltages fall within that 115–230V range at your desired operating current.

Yes. The IP67 rating means the driver is protected against temporary immersion and continuous water ingress, making it appropriate for sealed enclosures or damp/wet-location installations. The -40°C to +90°C operating temperature range adds further flexibility for environmental extremes.

Within the 320W DALI2 tier, the XLG-320-H-DA2 outputs 312W at up to 65V/5600mA for lower-voltage, higher-current strings; the XLG-320-L-DA2 outputs 315W at up to 340V/1400mA for long series strings; and the XLG-320-M-DA2 outputs 310.8W at up to 180V/2800mA, occupying the mid-range voltage and current position. All three share the DALI2 interface and IP67 rating.
