Frequently Asked Questions
Can I use the HLG-320H-C1050B with a 1-10V dimmer for warehouse LED high-bay fixtures?
Yes. The B suffix indicates a dimming signal input compatible with 1-10V, PWM, or resistance dimming. At 320.25W and 1050mA constant current, it can drive high-bay LED fixtures in the 152-305V range. pair with your 1-10V dimmer directly to the dimming input for smooth brightness control across the warehouse.
Is the HLG-320H-C1050B suitable for powering LED street lights with external dimming?
Yes. This driver provides 1050mA constant current at up to 320.25W with IP65 water resistance and a -40°C to +85°C operating range. The dimming input allows integration with smart street lighting controllers that use 1-10V or PWM signals for nighttime dimming schedules.
Can I use the HLG-320H-C1050B for dimmable LED retrofit fixtures in commercial spaces?
Yes. At 320.25W and 1050mA, it can power commercial LED fixtures with high-voltage series strings in the 152-305V range. The dimming input lets facility managers connect to existing 1-10V dimming infrastructure for energy-saving brightness reduction during off-peak hours.
Can the HLG-320H-C1050B drive LED modules in large illuminated advertising displays?
Yes. The 320.25W output at 1050mA constant current handles high-power LED module strings for large-format light boxes, billboards, or transit advertising panels. The dimming input is useful for reducing brightness at night to comply with local light pollution ordinances.
What CC voltage range does the HLG-320H-C1050B support for LED string sizing?
The constant-current voltage range is 152-305V at 1050mA. Your series LED string's total forward voltage must fall within this window. The number of LEDs you can connect in series depends on each LED's forward voltage. Sum the forward voltages and confirm the total is between 152V and 305V.
Can the HLG-320H-C1050B operate reliably in cold outdoor environments?
Yes. It is rated for operation from -40°C to +85°C, so it handles harsh winter conditions in outdoor cabinets or pole-mounted enclosures. The IP65 rating provides protection against dust and water jets. For installations fully exposed to rain or standing water, use an additional weatherproof enclosure.
