Bambu Lab AC Board HV for P2S – DLB054

Original high-voltage AC board (AC Board HV) for the Bambu Lab P2S 3D printer. This specialized board provides power supply to the heated bed with alternating current (AC) and its precise control via the main MC (motion control) board. Thanks to optimized power distribution, it provides stable temperature control, fast heating, and reliable operation even during long-term printing.

This part is designated by the manufacturer as BL‑DLB054 / DLB054 and is intended exclusively for the Bambu Lab P2S model. As an original Bambu Lab spare part, it guarantees full compatibility, safety, and preservation of the printer's print parameters.

Product description

Bambu Lab AC Board HV (DLB054) is a specialized control and power board that provides power to the heated bed of the Bambu Lab P2S 3D printer with alternating voltage. It is located in the electronic section of the printer and functions as an intermediary between the mains voltage and the heatbed, while being controlled by the main MC board.

Thanks to this, the printer can heat the bed to operating temperature quickly and at the same time maintain a stable temperature throughout the entire print, which is essential for first-layer adhesion and print quality.

The use of an original spare part from Bambu Lab ensures the correct operation of protection circuits, proper component sizing, and safe operation at the high power level of the heated bed.

Warning: Replacing the AC Board HV involves working with mains voltage. Installation should only be carried out by a qualified person with experience in electronics and safe work on mains-connected equipment.
