Advantages compared to traditional electromagnetic contactor control:

1. Accurate temperature control
2. Easy temperature setting with automatic linear recalibration—no need for time-consuming testing
3. Output power adjusts based on actual temperature needs—avoids overshooting and saves energy
4. SCR contains a built-in high-speed fuse that reacts quickly to heater faults, reducing impact on the power system
5. No contact arcing during load output, leading to longer lifespan than traditional systems
6. No mechanical noise during load output with SCR
