The Husqvarna 502542502 Frequency Inverter is a genuine OEM component designed for the PG680 and PG820 floor grinders. This inverter is sourced directly from Husqvarna, ensuring the electrical specifications, output frequency, and drive characteristics match exactly what these machines require. DHS Equipment supplies this part to help keep your floor grinder operating at full capacity.
Key Features
- OEM-Matched Electrical Specifications — Built to Husqvarna's exact output frequency and voltage drive parameters for the PG680 and PG820, ensuring the motor receives the precise power signal it was engineered to run on.
- Direct Drop-In Replacement — Designed to install into the existing inverter housing with original mounting points and electrical connections, restoring the drive system without adaptation.
- Compatible with PG680 and PG820 Floor Grinders — Confirmed fitment for both planetary floor grinder models, covering a wide range of professional surface preparation applications.
- Restored Motor Speed Control — A functioning frequency inverter gives the operator precise control over grinding head RPM, enabling consistent surface finish across varying concrete hardness and coating types.
- Electrical System Safety — Using the correct OEM inverter prevents mismatched frequency output that can damage the drive motor, cause erratic speed behavior, or trigger electrical faults during operation.
The frequency inverter controls the speed of the floor grinder's electric drive motor by converting incoming power to a variable output frequency. By adjusting that frequency, the machine can regulate grinding head RPM to match the demands of the surface being worked. When the inverter fails or produces incorrect output, the grinder may run at a fixed speed, behave erratically, or shut down entirely — making it impossible to maintain consistent grinding pressure or achieve a uniform finish. Replacing a faulty inverter with a correct OEM unit restores full variable-speed function and protects the drive motor from the strain of unregulated power delivery.
