Application Field of ECP40UT02

The ECP40UT02 is primarily designed for LED lighting applications, including indoor and outdoor LEDs, LED signs, and stage lighting. However, due to its high efficiency and reliable performance, the ECP40UT02 can be used in a wide variety of other applications, including automotive systems, solar and wind power systems, medical devices, industrial machinery and equipment, and consumer electronics.

This DC/DC converter features a maximum output power of 40W and a wide input voltage range of 9V - 30V DC. It can provide a wide range of output wattages, ranging from 0.5W to 40W. The ECP40UT02 also offers adjustable output voltages of 12V - 24V, making it suitable for a variety of different applications. Additionally, the converter features wide load regulation, ensuring that the output voltage stays stable even when the load changes.

The high efficiency of the ECP40UT02, up to 94%, allows it to be used in energy-efficient applications, such as LED lighting installations. Its low no-load power consumption and soft-start design also make it ideal for applications that require energy-saving design. The device is designed to withstand a wide temperature range from -40°C to 85°C, ensuring reliable performance in challenging environments.

Working Principle of ECP40UT02

The ECP40UT02 is a high-frequency transformer type AC/DC switch-mode power converter. It consists of an input rectifier, a mains filter, a transformer, a rectifying diode, an output current limiting circuit, an output voltage adjustment circuit, a main switching transistor, an output-side filter capacitor, a feedback control circuit, and a transformer drive stage.

The input rectifier and mains filter circuits convert AC input into DC supply voltage. The switching transistor is modulated on and off by the feedback control circuit in order to maintain a constant output voltage. The output voltage is also regulated by the output voltage adjustment circuit. The transformer, driven by the switching transistor, provides isolation between the input and output sides.

When the switching transistor is off, the feedback control circuit monitors the output voltage and compares it to the reference voltage. If it detects a difference between the two, it will adjust the switching frequency in order to maintain the output voltage. This feedback loop ensures constant output voltage even when the load changes.

The ECP40UT02 is designed with built-in protection, including over-voltage, over-current, overload, short-circuit, and thermal protection. All these protection functions are designed to help protect the converter from damage in case of fault conditions.

The ECP40UT02 is a versatile converter that is suitable for a wide variety of applications. Its high efficiency, wide input voltage range, and adjustable output wattages make it an ideal choice for LED lighting, automotive, solar, medical devices, industrial, and consumer electronics applications.
