Why Granite Saw Duty
Granite saws hit hard on startup and sustain high loads through the cut. This converter is oversized to handle both — no voltage drop, no stalling.
The AutoLink soft-start manages inrush current so your saw spins up smoothly without pulling your service voltage down.
Thermal overload, magnetic protection, and soft-start safeguard your saw motor from electrical damage during operation.
TEFC cast iron motor and IP65 panel handle the stone dust, water spray, and vibration typical in granite fabrication shops.
