TRV-075S024ST is a LED driver featuring power factor correction (PFC) function with multiple input voltage of 85~ 305Vac. It can provide constant current output and protect the LED lighting system from the over-voltage, over-temperature, over-current and short circuit effects.

The application field of the TRV-075S024ST LED driver includes but is not limited to LED indoor lighting, LED stage lighting, LED landscape lighting, LED high bay lighting, LED outdoor lighting, LED commercial lighting and architectural lighting.

The working principle of the TRV-075S024ST LED driver is governed by the active PFC switch mode power supply circuit and the Triac driving circuit, which are combined in one unit. The active PFC (Power Factor Correction) design of the LED driver can ensure no harmonic or transient current is emitted back to the power grid. The built-in Triac driving circuit helps provide a smooth and steady dimming control of the LED lighting system.

The basic components of the TRV-075S024ST LED driver are the active PFC circuit, rectifier, input filter, PFC controller, output filter, switching controller, output control indicator and Triac driver circuit. Firstly, the active PFC circuit increases the power factor of the LED driver by routing the inrush current back to the mains through a charged capacitor during the start-up phase. Secondly, the switching controller detects the voltage and current of the LED driver, and adjusts the output voltage to make sure that the LED driver supplies a constant voltage. Thirdly, the Triac driving circuit will provide stable and smooth dimming of the LED lighting system. Lastly, the output control indicator indicates the output current of the LED driver and the output voltage.

In conclusion, the TRV-075S024ST LED driver offers excellent low power factor, high efficiency, wide range input voltage and high performance features which make it an ideal choice for LED lighting applications. This LED driver can provide the reliable and efficient power supply for the LED lighting system, and protect it from the over-voltage, over-temperature, over-current and short circuit effects.
