LED drivers provide the most effective and efficient solution for powering numerous types of LEDs, from standard to highly efficient LED lighting fixtures. LED drivers are integral components within countless applications – from general illumination to industrial and automotive lighting, among others. This article takes an in-depth look at a specific type of LED driver, the PLM-40E-700, discussing its application field and working principle.

Overview of the PLM-40E-700

The PLM-40E-700 is an LED driver for large-scale LED lighting projects, and provides an ultra-low output ripple, a wide constant-voltage range, high efficiency, and a proven safe operating temperature. The ultra-low output ripple enables extremely strong flicker-free LED lighting, improved dynamics, and greater stability, while the wide CV range, high efficiency, and proven safe operating temperature make the PLM-40E-700 ideal for other LED lighting applications. The product is designed for high drive current (up to 700mA) and can handle up to 10A in mains operation.

Application Field and Working Principle of the PLM-40E-700

The PLM-40E-700 is a high-power LED driver that can be used in a wide range of environments for various applications. It is suitable for commercial and industrial LED lighting installations, such as supermarkets, malls, and factories, in which large-scale LED lighting is required. The LED driver is engineered to provide a stable output voltage, adjustable from 11V to 40V, enabling precise LED lighting control.

The PLM-40E-700 LED driver is composed of a switching power supply circuit with feedback of the output voltage by a sense resistor, and its operation voltage is adjustable from 11V to 40V. It works in several stages: power transmission, power storage, power conversion, and power absorption. First, electricity from an AC source is transmitted to the power store (inverter) and converted to DC power. This power is then transmitted to the power conversion stage, which is composed of a PWM-controlled MOSFET switch and a sense resistor, and converts the DC power to AC. Lastly, the power is absorbed by the LEDs via the inverter.

The MOSFET switch and sense resistor regulate the output voltage according to the input signal, and are important components that ensure efficient and reliable performance of the PLM-40E-700 LED driver. The MOSFET switch is a high-speed power switch that rapidly turns the switching power supply circuit on and off in response to the input signal. The sense resistor, which is located in the LED driver, senses the output voltage and feedback voltage to the control circuit, which then adjusts the output voltage accordingly. This allows for stable and precise output voltage control.

Conclusion

The PLM-40E-700 is an LED Driver with high drive current and many advantages, such as ultra-low output ripple, wide constant-voltage range, high efficiency, and safe operating temperature. Its application field is suitable for large-scale LED lighting projects in commercial and industrial settings, and its working principle is based on a power transmission, power storage, power conversion, and power absorption system. All of these components, along with its reliable and efficient performance, make the PLM-40E-700 a powerful and versatile LED driver.
