HLG-120H-20

LED Drivers

LED Drivers are essential in controlling the power of LEDs and ensuring that their voltage and current requirements are correctly supplied. One of the most common applications for this is in computing and communication applications, where the LED drivers are responsible for accurately controlling the voltage and current applied to the LEDs.

The HLG-120H-20 is a type of LED driver that is designed to provide a high level of control over the LED power output. This model has a range of input voltage from 100–277VAC, and a wide range of dimming capabilities from 0–10V or PWM signal. It also offers adjustable current output, with a maximum current of 20A.

Application Field

The HLG-120H-20 is most commonly used in the automotive and industrial sector, as well as in outdoor lighting applications. The adjustable current output, dimming capabilities, and wide range of input voltages make it a great choice for applications where precise lighting levels are needed. This LED driver can also be used in multiple lighting fixtures for complete lighting control, with the ability to operate up to 10 lighting fixtures at a single time.

Working Principle

The HLG-120H-20 operates on a linear current boost design. It can provide a maximum output of 20A and a wide range of dimming levels. This makes the unit capable of dimming at 0–10V or PWM signals. The HLG-120H-20 is also capable of dimming down to 1W per channel.

The LED driver has an internal chip that continuously monitors the output current to ensure it remains stable and is within the specified range. The unit also features over-temperature protection, over-voltage protection, and short-circuit protection. This ensures increased reliability and protects the driver from damage due to external conditions.

In conclusion, the HLG-120H-20 offers a wide range of features for LED light control and dimming. Its adjustable current output, wide range of input voltages, and dimming capabilities make it a great choice for automated lighting applications.
