LED Drivers: HLG-120H-30 Application Field and Working Principle

Among the many types of LED drivers available in the market, the HLG-120H-30 offers excellent performance and reliability that make it suitable for a wide range of applications. The HLG-120H-30 is a constant-current LED driver designed specifically for LED-based lighting systems, and it is able to provide stable, programmable output current for a variety of LED types including high power LEDs such as COB-type components. The driver also offers an efficiency of up to 95% and an output voltage of 24V.

The HLG-120H-30 is suitable for both indoor and outdoor lighting applications, and its IP67 water-resistance rating ensures reliable performance even in wet conditions. It also offers a variety of protection features to guard against extreme temperatures and overloads. Furthermore, the driver is designed for both AC and DC input, allowing it to be used with both conventional mains power supplies and solar applications.

The HLG-120H-30 is equipped with pulse-width modulation (PWM) dimming functionality to dim LED light fixtures without flicker, and its adjustable output current allows for precise tuning of the light intensity for a wide variety of applications. The dimming range can be set between 0.1V and 24V, and the current can be set as low as 10 mA for low power LED operations.

In terms of its working principle, the HLG-120H-30 operates via a DC-DC switching power supply. This works by switching between two power transistors in order to convert one DC voltage to another, in this case from the mains AC voltage to the necessary DC voltage for the LED driver. The power transistors are switched on and off at a very high rate, enabling the voltage to be rapidly varied. The speed of the switching, and the voltage of the output, can be adjusted via the control inputs.

The HLG-120H-30 can be used in a variety commercial, industrial and residential LED lighting applications, due to its high level of performance and flexibility. It is easy to install, as it requires no additional setup or wiring. Furthermore, its adjustable output current ensures that it can accurately deliver the desired lighting intensity for any situation. In conclusion, the HLG-120H-30 is an excellent LED driver that offers superior performance and reliability for a wide variety of LED lighting applications.
