Frequently Asked Questions
Can I use the HLG-120H-C1400B with a building management system to dim LED ceiling fixtures?
Yes. The HLG-120H-C1400B accepts 1-10V and PWM dimming signals, which are standard outputs from most building management systems. It delivers 1400mA constant current at up to 151.2W, making it suitable for centrally controlled ceiling-mounted LED fixtures in offices, lobbies, and corridors.
Is the HLG-120H-C1400B suitable for dimmable LED flood lights on a building exterior?
Yes, provided the flood light LEDs draw 1400mA with a total forward voltage between 54V and 108V. The IP65 rating protects against rain and dust in exterior installations, and the dimming input allows nighttime brightness reduction for energy savings or light pollution compliance.
Can the HLG-120H-C1400B drive LED modules in a display case with dimming control?
Yes. At 1400mA constant current with a 54-108V CC range, the HLG-120H-C1400B can power LED modules used in retail display cases, museum showcases, or jewelry vitrines. The dimming input lets you set the exact brightness level needed for product presentation without an external current-limiting device.
What happens if my LED string voltage is outside the 54-108V CC range of the HLG-120H-C1400B?
If the total LED forward voltage falls below 54V or exceeds 108V, the driver cannot maintain its regulated 1400mA constant current output. Below the minimum, the driver may shut down or operate erratically. Above the maximum, it will not deliver enough voltage to push 1400mA through the load. Always ensure your string voltage falls within the 54-108V window.
Can the HLG-120H-C1400B operate in a cold-storage facility or walk-in freezer?
Yes. The HLG-120H-C1400B is rated for operation from -40°C to +90°C, which covers cold-storage and freezer environments. The IP65 enclosure also protects against moisture from condensation and frost. The aluminium casing resists corrosion that can occur in high-humidity cold environments.
How does the HLG-120H-C1400B compare to the C1400A and C1400AB models?
All three deliver 151.2W at 1400mA constant current over a 54-108V CC range with IP65 protection. The C1400B (this model) includes a 1-10V/PWM dimming input but no output adjustment potentiometer. The C1400A offers the potentiometer for manual output trimming but no dimming input. The C1400AB has both features.
