Buying from the Right Source - Avoid fake parts buy from trusted sellers such as IC-Components. Check pricing and availability before ordering.

DF60BA80 Circuit Diagram

DF60BA80 Circuit Diagram

The circuit diagram shown represents the internal structure of the DF60BA80 three-phase bridge rectifier module. This module is designed to convert an AC input into a DC output using six internally connected diodes arranged in a three-phase rectifier configuration.

At the top, terminals 1~, 2~, and 3~ serve as the three-phase AC input connections. Each of these inputs is connected to a pair of diodes in a bridge arrangement. The diodes are oriented to allow current to flow in only one direction, ensuring rectification of the AC waveform. The cathodes of the upper diodes and the anodes of the lower diodes are connected to the DC output terminals.

The +4 terminal represents the positive DC output, where the rectified voltage is collected, while the −5 terminal serves as the negative or ground connection. This configuration ensures that the module efficiently converts three-phase AC into a stable DC supply, making it suitable for industrial motor drives, power supplies, and other high-power rectification applications.

DF60BA80 Mechanical and Mounting Details

DF60BA80 Mechanical and Mounting Details

The DF60BA80 mechanical dimensions and mounting details provide information for proper installation and integration into electrical systems. The module has an overall width of 80 mm and a height of 35 mm, with a base width of 60 mm, ensuring a compact yet robust design for industrial applications.

The top view shows the layout of the terminal connections, spaced 21.5 mm apart, with a central spacing of 10 mm between specific terminals. The module includes five M5 screw terminals, which provide secure electrical connections for both AC input and DC output.
