Frequently Asked Questions
Can I use the HLG-240H-C1050AB for dimmable LED high-bay lighting in a warehouse?
Yes. The HLG-240H-C1050AB delivers 1050mA constant current at 249.9W with both adjustable output and 1-10V/PWM dimming. This suits high-bay fixtures where brightness needs to change based on occupancy or daylight levels. The LED string voltage must fall within the 119-238V CC range.
Is the HLG-240H-C1050AB suitable for dimmable commercial LED panel arrays?
Yes. At 249.9W and 1050mA, it powers medium-to-large LED panel arrays with series string voltages between 119V and 238V. The dimming input integrates with building management systems for scheduled or sensor-driven brightness control, and the adjustable output lets you calibrate current to your panels' optimal operating point.
Can the HLG-240H-C1050AB drive LED modules for large illuminated signage with dimming?
Yes. The 1050mA constant current output handles large sign module arrays whose combined forward voltage stays within 119-238V. The 1-10V/PWM dimming input enables day/night brightness scheduling, and the adjustable output trims current to match your specific LED module requirements.
What dimming methods does the HLG-240H-C1050AB support?
The HLG-240H-C1050AB accepts 1-10V analog and PWM dimming signals through its built-in dimming input. This allows integration with standard wall dimmers, lighting controllers, and building automation systems. The adjustable output potentiometer provides an additional level of static current calibration independent of the dimming signal.
How does the HLG-240H-C1050AB handle humid or dusty industrial environments?
Its IP65 rating provides full dust protection and resistance to low-pressure water jets from any direction. Combined with an operating temperature range of -40°C to +90°C and an aluminium casing for efficient heat dissipation, it performs reliably in warehouses, production floors, and covered outdoor industrial areas.
What LED string voltage range is compatible with the HLG-240H-C1050AB?
The CC voltage range is 119-238V. Your LED series string's total forward voltage must fall within this window. The driver automatically regulates its output voltage to deliver a steady 1050mA to the load. The number of LEDs in series depends on each LED's forward voltage.
