LED Drivers commonly refer to power electronic devices used to drive and control LEDs in numerous applications. PWM-120-12DA is a type of LED driver, featuring wide input voltage range and multiple dimming options, allowing for an array of creative lighting designs. It is a product manufactured by both SEL and Leadwell Technology, and is one of the most commonly used LED drivers. Let’s take a closer look at the application areas and working principle of PWM-120-12DA LED driver.

Application Field

PWM-120-12DA LED drivers have immense popularity due to their wide range of functions and application areas. These drivers can provide an efficient dimming for both DC and AC LED bulbs and modules, and are particularly applicable in commercial lighting, industrial lighting, decorative lighting, residential lighting, automotive lighting and architecture illumination. Moreover, such LED drivers also guarantee the safety and protection of the devices connected to them.

The product offers many advantages, such as high efficiency, multiple dimming choices, various input voltage range (90-305VAC), external dimming interface, and constant current constant voltage. All these features have made it a top choice for people looking to install high-quality and durable LED lighting systems in different places. The product is also environmentally friendly, being compliant with RoHS regulations.

Working Principle

The PWM-120-12DA LED driver features a unique PWM (Pulse width modulation) dimming control technology to adjust its output current. This is done by the use of its built-in microcontroller, which modulates the pulse width of the AC power input to an optimal level, so that the LED brightness is adjusted to the desired value. Every time the pulse width varies or changes, the average current passing through the LED also varies, allowing for complete control over the LED brightness.

The LED driver is integrated with Japanese imported FET and low-loss capacitor, which gives it excellent thermal performance and a low electromagnetic interference character. When it comes to protection, the product offers OVP (Over Voltage Protection) and SCP (Short Circuit Protection) to protect the connected device from any potential damage.

PWM-120-12DA LED driver also supports ON/OFF and dimming control via its external interface. The user can control the LED brightness from both switch and dimming mode, allowing for full flexibility in terms of usage and customization. The product is compatible with a number of different LED bulbs and modules, making it widely applicable in various lighting applications.

Conclusion

In conclusion, PWM-120-12DA LED driver is an ideal choice if you are looking for a reliable, efficient and cost-effective LED driver with various dimming options. It is applicable in various lighting applications such as commercial lighting, industrial lighting, decorative lighting, residential lighting, automotive lighting and architecture illumination, and is compatible with a number of LED bulbs and modules. The product features an advanced PWM dimming control technology, allowing you to adjust its output current with great precision, and the built-in OVP and SCP ensures the safety and protection of the connected device.
