ELG-75-12DA LED Drivers

The ELG-75-12DA LED driver is a highly efficient, low voltage switching current regulator designed to provide illumination and power for a wide range of light emitting diode (LED) applications. This type of LED driver is commonly used in commercial and residential LED lighting applications, such as accent lighting, wall washing, task lighting, and low to medium output lighting.

Maximum Efficiency

The ELG-75-12DA’s maximum peak efficiency is 94%, making it one of the most efficient LED drivers on the market. The low power conversion loss, coupled with the low quiescent current, allows for superior overall system efficiency. In addition, this LED driver is capable of hot temperature start-up and low-load operation.

High Power Density

The ELG-75-12DA is designed to provide a high power density, meaning that it can output a large amount of power over a relatively small footprint. It has a maximum output power of 75 watts and a minimum output voltage of 9 volts, making it ideal for a variety of applications. It is also designed to operate over a wide range of temperatures (-40°C to 85°C) and has a low voltage start-up feature.

Applications

The ELG-75-12DA LED driver is typically used in applications that require low to medium power, such as accent lighting, wall washing, task lighting, and backlighting. It is also suitable for high efficiency LED systems, such as industrial lighting, automotive lighting, and marine lighting. The ELG-75-12DA’s low profile makes it easy to install in tight spaces, such as ceiling lights, wall sconces, and under-cabinet fixtures.

Working Principle

The ELG-75-12DA LED driver relies on the principle of regulated high-efficiency-conversion, which uses a combination of high-frequency PWM voltage control, precise constant current control, and high-efficiency switching power supply topology to convert a small input voltage into a regulated output current. This unique design allows the LED driver to maintain a constant output current while efficiently converting the input power into illumination. By controlling the voltage and current applied to the LEDs, the driver is able to maintain a constant brightness level regardless of input voltage changes or LED temperature.To ensure a high degree of accuracy, the ELG-75-12DA LED driver includes two external resistors - one to adjust the constant current output and the other to adjust the minimum current output. This allows for easy adjustment of the output current to match the LED manufacturer’s specified operating current. In addition, this driver features a built-in temperature protection circuit, which automatically turns off the output voltage if the temperature exceeds a certain threshold.

Conclusion

The ELG-75-12DA LED driver is a highly efficient, low voltage switching current regulator designed to provide illumination and power for many light emitting diode (LED) applications. Its high efficiency, high power density, and wide temperature range make it an ideal solution for low to medium power applications. The adjustable output current and temperature protection circuit make it easy to adjust the driver to achieve the desired illumination level and protect the LEDs against excessive heat.
