Frequently Asked Questions
Can I use the HLG-480H-C1750B for dimmable LED street lighting projects?
Yes. The HLG-480H-C1750B delivers 480W at 1750mA constant current with a built-in dimming input (1-10V/PWM). This supports midnight dimming and adaptive lighting programs commonly used in municipal street lighting to reduce energy consumption during low-traffic hours. The IP65 rating protects the driver inside pole-top housings.
Is the HLG-480H-C1750B suitable for large commercial LED panel ceiling installations with dimming?
Yes. At 480W and 1750mA, it can drive high-power LED panel arrays in commercial ceilings, lobbies, or atriums. The B suffix provides external dimming via 1-10V or PWM, which integrates with building management systems for daylight-responsive or scheduled brightness control.
Can the HLG-480H-C1750B power dimmable LED modules in large illuminated signage?
Yes. The 1750mA constant current output with a voltage range of 137-274V can drive long series strings of high-power sign LEDs. The dimming input allows automated brightness scheduling, such as reducing sign intensity after business hours or dimming in response to ambient light sensors.
What is the CC voltage range of the HLG-480H-C1750B and how does it affect LED compatibility?
The constant current regulation range is 137-274V. Your total series LED string voltage must fall within this window for the driver to maintain a steady 1750mA. The number of LEDs you can connect depends on each LED's forward voltage. If the string voltage falls outside this range, the driver will not regulate current properly.
Can the HLG-480H-C1750B handle high-temperature environments near LED fixtures?
Yes. It is rated for -40 to +90 degrees Celsius operating temperature, which accommodates mounting near heat-generating LED fixtures or in unventilated enclosures. The aluminium casing acts as a heat sink, and the IP65 sealing prevents dust accumulation that could impair thermal dissipation.
What is the difference between the HLG-480H-C1750A, C1750AB, and C1750B?
All three share the same 480W / 1750mA core specs with a CC voltage range of 137-274V and IP65 rating. The C1750A has output adjustment via built-in potentiometer but no dimming input. The C1750AB offers both potentiometer adjustment and external 1-10V/PWM dimming. The C1750B provides external dimming input only without the adjustment potentiometer.
