LED (Light Emitting Diode) drivers are power supplies that modulate the amount of current and voltage that goes through an LED light source. The HLG-480H-30A is a constant current LED driver. It is specially designed to use with 1-10 pieces of high-power LEDs in series. The HLG-480H-30A offers a wide input voltage range of 85-305VAC, and offers three constant currents of 400mA, 800mA, and 1200mA. It is certificated for CE, UL, and FCC and has advantages of high efficiency, long lifetime, and high precision constant current control.

The HLG-480H-30A is mainly used in indoor and outdoor lighting, LED display and signs, and LED residential lighting applications. It is usually used to replace traditionally designed electronic power supplies in order to save energy and reduce cost. It is designed to be used in damp or dry locations. An HLG-480H-30A driver can be used to power LED strip lights, or other high power LED lighting.

The working principle of the HLG-480H-30A is that of a buck regulator. A buck regulator is an electronic power switch that takes energy from a higher voltage source and converts it into a lower voltage output. When the LED driver is connected to the main power supply, the voltage is first rectified by the bridge rectifier. Then, the voltage is stepped down by the primary side MOSFET and a second rectification is used to obtain a DC voltage. This DC voltage is then converted to a constant current by the power factor correction controller. This constant current is then used to power the LED\'s.

The HLG-480H-30A is designed with constant current control functions, short circuit protection, over voltage protection, and various dimming features. It also has a two-level current output mode so it can be used with both high power and low power LED\'s. With its high efficiency up to 91%, it reduces energy costs and helps reduce heat dissipation. The UL certificated HLG-480H-30A ensures safety and reliability. The long lifetime and low maintenance make it an ideal choice for various LED applications.

The HLG-480H-30A driver is a powerful and versatile power supply for LED lighting applications. It is highly efficient, with a wide input voltage range, and offers a variety of output current selections. With its short circuit protection, and high reliability it is an ideal choice for various LED lighting projects. The HLG-480H-30A is designed to be used for indoor and outdoor lights, LED displays, and LED residential lighting applications.
