Key Features
- OEM-Matched Control Circuitry — Built to Husqvarna's exact electrical specifications, this Electronic Box delivers the correct signal outputs and protection thresholds required by the floor grinder's motor and drive system.
- Direct-Fit Replacement — Designed to install in the original mounting position with the same connector configuration, allowing a straightforward swap without modification to wiring harnesses or housing brackets.
- Confirmed Fitment for HTC280, PG280, PG400, and PG450 — Engineered specifically for this group of Husqvarna planetary floor grinders, so you can order with confidence knowing the part is designed for your machine.
- Restored Grinder Control Performance — A functioning Electronic Box governs motor speed, load management, and operational safety responses. Replacing a failed unit restores stable, consistent grinding output and protects downstream components from erratic power delivery.
- Electrical Safety Compliance — As the central control unit for the machine's electrical system, using a genuine OEM Electronic Box ensures the grinder's built-in overload and fault-response behavior performs as Husqvarna designed it, reducing risk of electrical faults on the work floor.
The Electronic Box is the central control unit that manages electrical input and output across the floor grinder's operating systems. It regulates motor speed, monitors load conditions, and coordinates the machine's protective shutdown responses when fault conditions are detected. When this component fails or becomes damaged, the grinder may exhibit erratic speed control, fail to start, or shut down unexpectedly — making prompt replacement with a genuine OEM part essential to restoring safe and productive operation.
