HSG-70-24

LED drivers are devices that control the operation of light-emitting diodes (LEDs) and their associated lighting systems. HSG-70-24 is a type of LED driver that offers high efficiency and performance. The following article will discuss the application field and working principle of the HSG-70-24.

Application Field

HSG-70-24 is a type of LED driver specifically designed for lighting applications, including LED streets, LED tunnel lights, and LED display screens. It is particularly suitable for LED lighting applications that require extremely high luminous efficiency––up to 150lm/W––and long operational lifetimes. As a result, this driver is becoming increasingly popular among lighting professionals and designers.

Working Principle

The HSG-70-24 LED driver utilizes a constant voltage output to precisely regulate the LED load. It controls the output current by adjusting the pulse width modulation (PWM) signal and varying the LED current. It also features over-current, over-voltage, and open circuit protection to ensure the safety and reliability of the system. With a wide range input voltage between 90VAC and 270VAC, the HSG-70-24 is able to operate in a variety of different settings. In addition, the driver is able to operate at temperatures from -40° C to +85° C, making it suitable for a range of extreme conditions.

The HSG-70-24 LED driver is engineered with a hybrid architecture that combines the power factor corrector (PFC) passive stage and a DC-DC buck-mode converter active stage. This allows the driver to offer high efficiency while also providing excellent power factor, improved current waveform, and improved lighting performance. The PFC stage of the driver is comprised of a single stage planar transformer, a PFC boost rectifier, and an energy storage output filter. The DC-DC buck-mode converter, meanwhile, utilizes switch mode techniques to control the output current.

Conclusion

The HSG-70-24 is a high performance LED driver designed for use in LED lighting applications. It offers excellent efficiency and power factor, as well as the necessary protection features for reliable operation. With its wide input voltage range and operating temperature range, the HSG-70-24 is a cost-effective and reliable LED driver suitable for professional and commercial lighting installations.
