Commercial Induction Cooker 9-Level Magnetic Control Circuit Board
## 1. Product Overview
Our factory manufactures the 9-level knob magnetic control circuit board for commercial induction cookers. It uses a standard DC5V Hall-effect contactless sensing solution with rotary knob control, providing 9-level linear voltage output for power signals. The gear identification is stable and resistant to shifting or jumping in kitchen environments with vibrations and smoke.

## II. Core Process Advantages
1. Hall contactless sensing structure
Replace traditional metal contacts with magnetic sensing for gear switching. Eliminates oil contamination, oxidation, contact burning, and gear failure—delivering a service life far exceeding standard switch PCBs.
2. Heavy-duty, triple-protected industrial PCB
Reinforced fiberglass PCB with widened copper traces and full-panel nano-conformal coating for waterproof, oil-proof, and moisture-proof protection. Withstands high-temperature splashes from kitchen cooking fluids and ensures reliable operation without short circuits during continuous use.
3. 9-segment precision firepower gradient
9-level power control with clear gradients—from low-heat warming and slow simmering to steaming, braising, stir-frying over medium heat, and high-power searing. Smooth power transitions meet all culinary needs across diverse foodservice operations.
4. EMC Interference Suppression Design
Fully automated SMT assembly with built-in electromagnetic interference (EMI) suppression circuitry, designed for 380V high-power commercial induction cooktops. Eliminates signal interference, black screen issues, and heating level drift.

## 3. Compatible Cooktop Range
Compatible with 6KW-30KW commercial electromagnetic equipment: single and double wok ranges, cafeteria boilers, stock cookers, noodle cookers, clay pot cookers, and multi-burner induction stoves for food courts.
Suitable for full appliance integration in cookware factories and replacement of old stoves. Standard wiring terminals allow direct installation without stove modifications.

## IV. Supply and After-Sales Support
1. In-stock bulk shipping; supports small-batch purchasing and long-term stable supply for OEMs.
2. Customization supported: voltage divider parameters, flex cable length, terminal definitions, and PCB silkscreen logos.
3. Factory-tested for 72 hours with power-on aging and high/low temperature simulation for strict quality control and low defect rates;
4. Includes professional wiring guidance, stable warranty, and supply to cookware manufacturers, repair shops, and kitchen engineering contractors.
