Multi-channel High-power Power Drive PCBA

This multi-channel high-power power drive PCBA has finished dimensions of 150mm×139mm. It is an FR-4 multilayer PCB with green solder mask, manufactured with one-stop service of PCB fabrication and precision SMT assembly. A dedicated footprint area is reserved for the main control chip. The board is equipped with multi-channel power MOSFETs, high-power power inductors and high-voltage electrolytic capacitors. Multiple PEM self-clinching studs are arranged along the board edge for high-power multi-channel output control.

It integrates Type-C debug port and multiple signal connectors to support independent high-current output of multiple channels, with over-current, over-voltage and short-circuit protection. Widely used in industrial power modules, high-power load drivers and power supply control for industrial automation equipment.

Juehui Weiye Circuit undertakes custom PCBA for high-power power supplies. We support high-current PCB layout design and precision SMT assembly of high-power devices for prototype and mass production of PCBA used in industrial power and new energy equipment.
