LED Drivers, also known as LED power supplies, LED power sources, LED converters, LED controllers or LED ballasts, are at the heart of all LED lighting systems. Among them, the LXV200-012S is a driver for high power LED lighting applications. It applies to a wide variety of applications from indoor light to outdoor lighting, and is a valuable tool to make LED lighting systems energy efficient and reliable.

Features

The key features of the LXV200-012S include:

• High power factor (> 0.9)
• Up to 90% conversion efficiency
• CC/CV main circuit control
• High-output current accuracy
• Small size and light weight
• Integrated input/output overvoltage, overcurrent, and overheating protection

The LXV200-012S is designed to operate with up to different voltage functions, such as 15V for high power, 12V for medium power and 9V for low power. It provides constant current outputs from their respective voltage inputs. This power converter is also designed for high-temperature operation as it comes with an internal temperature sensor along with EMI filter and low external components.

Working Principle

The important components of the LXV200-012S include a power switch (usually MOSFET), an energy transfer device (usually induction coils), a control module, a voltage sensing module, a voltage sensors, a current sensor, a temperature sensor, a protection circuit, etc.

When the power is switched on, the power switch is turned on and it turns on the energy transfer device. In this state, the power converter works like a transformer to transfer the input power to the correct output voltage and current. The control module is used to control the operation of the power switch to ensure the output voltage and current are precisely controlled.

The voltage sensing module is used to detect the input voltage and adjust the output voltage accordingly. It also provides feedback on the input voltage which is used to control the power switch thereby controlling the output current. The current sensor is used to detect the output current and to adjust the output current accordingly. The temperature sensor is used to detect the temperature at which the converter is operating and to adjust the output power accordingly.

In addition, the protection circuit provides protection against input/output overvoltage, overcurrent, and overheating. This helps to ensure the safety of the converter and improve its reliability.

Applications

The LXV200-012S is suitable for a wide range of applications such as:

• High-dimming backlight lighting
• LED lighting/illumination systems
• LED signboards
• Industrial LED lighting systems
• High bay lighting
• Light show exhibit lighting
• Street lamps
• Emergency lights
• Commercial lighting systems

Conclusion

The LXV200-012S is a highly efficient and reliable LED Driver for a wide variety of lighting applications. Its ability to deliver high power factor, up to 90% conversion efficiency and precise current/voltage control makes it a valuable tool for energy efficient and reliable LED illumination. Its wide range of application fields makes it the perfect choice for all LED lighting systems.
