Key Features
- OEM Electrical Specification Match — built to Husqvarna's precise output and control parameters for the PG and HTC floor grinder platform, ensuring correct motor regulation and grinder response.
- Drop-In Replacement — engineered to the same connector layout, mounting footprint, and wiring configuration as the original, allowing a straightforward swap without adapting harnesses or brackets.
- Broad Floor Grinder Compatibility — fits the PG280, PG400, PG450, PG510, PG510I, and HTC510 planetary floor grinders, covering multiple machine generations in the PG and HTC lineup.
- Restored Machine Control — a functioning electronic box governs motor speed and operational sequencing; a failed unit can result in erratic behavior, failure to start, or loss of speed control, all of which this genuine replacement corrects.
- Electrical Safety Integrity — as the central control component for the grinder's electrical system, using a genuine OEM unit ensures proper circuit protection and compliance with the machine's original design intent.
The electronic box is the central control unit that manages power delivery and motor operation on the floor grinder. It regulates the electrical signals that govern motor speed, start-up sequencing, and operational response, making it essential to consistent, controlled grinding performance. When this component fails, the machine may refuse to start, run erratically, or lose the ability to maintain steady speed across the grinding head — symptoms that a genuine OEM replacement like the 582506903 directly resolves.
