AC Power Board – Compatible with X1 and P1 Series

Product Overview

The AC Power Board is a dedicated circuit board designed to manage and distribute alternating current (AC) power directly to the heated bed of Bambu Lab 3D printers. This component plays a vital role in the safe and efficient operation of the heatbed system, which is responsible for ensuring proper adhesion of prints and minimizing warping during the printing process.

This board is specifically engineered for use with both the X1 Series and P1 Series printers, delivering stable high-voltage power required by the heatbed while adhering to strict safety standards. Its robust design and precision manufacturing help maintain thermal consistency throughout the entire printing process.

By offloading the high-voltage AC supply directly to a separate and insulated module, the AC Board reduces strain on the printer's mainboard and contributes to the long-term reliability and safety of your 3D printer.

Key Features

• Supplies regulated AC power directly to the printer's heated bed
• Engineered for high thermal and electrical safety standards
• Supports stable and consistent heat distribution across the bed
• Minimizes electrical load on the printer's main control board
• Pre-installed connectors for seamless replacement and installation

Installation Guide

Installing or replacing the AC Board is a moderately simple procedure that requires basic technical knowledge and care when working with high-voltage components. Bambu Lab provides a detailed step-by-step tutorial, complete with diagrams and safety instructions, available on the Bambu Lab Wiki.

Warning: Always power off and unplug your printer before performing any repairs or hardware replacements. Mishandling AC power components can result in electric shock or hardware damage.
