• It is also compatible with a variety of controls, including 0-10V dimming, external dimming, and PLC.

Working Principle

The working principle of the PDA100B-48VG LED driver is based on the switch-mode design. This type of driver utilizes a constant-current converter circuit to drive the LED. The device operates by converting the input voltage to a different voltage that is suitable for the LED. The output of the device is regulated to the configured current, determined by the user. As the input voltage changes, the device adjusts the output voltage and current accordingly to maintain the specified output.

The device also uses a step-down transformer and voltage regulator to adjust the output voltage and current. In addition, the device is designed to minimize electromagnetic interference and power consumption. This ensures that the LED runs efficiently and does not interfere with other electronic components.

Conclusion

The PDA100B-48VG is an ideal LED driver for low voltage applications. The device is designed to be small and efficient, while still offering a wide range of features and benefits. The device utilizes a switch-mode design to regulate the output voltage and current and can be used in a variety of LED applications, such as LED lighting, LED billboard displays, LED street lighting, architectural lighting, and industrial lighting.
