Description:
The AC Board is the primary circuit board responsible for receiving mains AC voltage and distributing it to the printer's power-hungry components, specifically the heated build plate.
Unlike the electronics on the toolhead, the AC board manages high-voltage power. The V2 revision features optimized circuitry and improved power-delivery components to ensure consistent heating performance and long-term durability. It is a direct OEM replacement part, essential for resolving issues where the bed fails to heat or when the printer suffers from intermittent power loss.
Features:
High-Power Distribution: Safely manages up to 1300W (at 220V) or 350W (at 110V) for rapid heatbed warming.
Safety Optimized: Features integrated fuse protection and a relay system to prevent electrical overloads.
V2 Updated Design: Includes improved internal layout and components to address the thermal requirements of long-duration high-temperature printing.
Direct Integration: Communicates with the MC (Motion Controller) board via a specialized interface cable to sync heating cycles with print commands.
Solid State Reliability: Designed for a long service life with industrial-grade soldering and components.
