The Husqvarna 581774904 Circuit Board Assembly 230V Dm220 is a genuine OEM replacement designed for the DM220 concrete core drill. As an authentic Husqvarna component, this assembly is built to the exact electrical specifications required by the DM220, ensuring correct voltage regulation, motor control, and overall system operation. DHS Equipment supplies this part to help keep your core drilling equipment running at full capacity.
Key Features
- OEM Electrical Specification Match — Manufactured to Husqvarna's exact 230V output and resistance tolerances, so the circuit board integrates seamlessly with the DM220's motor control system without signal mismatch or operational error.
- Direct Drop-In Replacement — Designed to mount and connect using the original harness connectors and board mounting points on the DM220, keeping the installation straightforward for qualified service technicians.
- Confirmed DM220 Fitment — Purpose-built for the DM220 concrete core drill motor; cross-reference part number 581774904 against your parts diagram to confirm compatibility with your specific unit.
- Restored Motor Control Performance — A functioning circuit board delivers consistent power delivery and speed regulation to the drill motor. A failed or damaged board can result in erratic motor behavior, loss of speed control, or complete machine shutdown.
- Electrical Safety Compliance — Using the correct OEM board maintains the DM220's designed overcurrent and fault-protection logic, which is critical for operator safety on 230V jobsite equipment.
The circuit board assembly serves as the electronic control center for the DM220 drill motor, managing power delivery, motor speed, and protective shutoff functions at the 230V operating voltage. When this board degrades or fails, the drill may lose consistent speed control, fail to start, or trigger unexpected shutdowns — all of which interrupt core drilling operations and can place additional stress on connected components. Replacing it with the correct genuine OEM assembly restores the designed electrical behavior and ensures the motor operates within its intended parameters.
