Frequently Asked Questions
Can I use the HLG-320H-C700AB to power dimmable LED high-bay fixtures in a warehouse?
Yes. The HLG-320H-C700AB provides 700mA constant current at up to 299.6W with both an adjustable output and a 1-10V/PWM dimming input. This allows daylight harvesting or occupancy-based dimming in warehouse high-bay installations. The fixture's forward voltage must fall within the 214-428V CC range.
Is the HLG-320H-C700AB a good choice for dimmable commercial LED signage?
Yes. The 700mA constant current output across a 214-428V CC range can drive long series strings of LED modules used in channel letters and large illuminated panels. The dimming input allows scheduling day and night brightness levels, and the adjustable potentiometer lets you trim current to your modules' optimal operating point.
Can I use the HLG-320H-C700AB with a 0-10V building automation dimmer?
Yes. The AB suffix indicates a 1-10V/PWM dimming input that is compatible with standard 0-10V or 1-10V dimming signals from building automation systems, occupancy sensors, or standalone dimmers. Combined with the potentiometer for maximum current adjustment, you get full control over light output from the connected LED string.
Can the HLG-320H-C700AB be mounted in a covered outdoor location?
Yes. Its IP65 rating protects against complete dust ingress and low-pressure water jets, suitable for soffits, ventilated enclosures, or covered canopies. It is not rated for submersion. If the installation may be exposed to standing water or heavy flooding, consider the IP67-rated HLG-320H-C700DA with DALI control.
How many LEDs can I run in series with the HLG-320H-C700AB?
The exact number depends on each LED's forward voltage. The driver operates at 700mA constant current with a CC voltage range of 214-428V, which accommodates very long LED series strings. Sum the forward voltages of your LEDs and confirm the total falls within that range. The built-in potentiometer allows fine-tuning the output.
What is the operating temperature range of the HLG-320H-C700AB?
The HLG-320H-C700AB operates from -40°C to +85°C, covering extreme cold and hot environments. The aluminium casing aids heat dissipation. In enclosed spaces near the upper limit, provide adequate airflow or reduce the load to maintain the driver's 7-year warranty life expectancy.
