Knob Motor Speed Controller 220V 18A SCR Voltage Regulator 4KW Stepless Variable Speed Controller Switch Thermostat with Socket
Features:
- Widely used
- Zero latency, zero latency,
- Double-sided copper-platinum welding is safer and more secure
- The peak voltage absorption circuit effectively protects the high-power thyristor against surges, spikes, and RC absorption with multiple protections
- High-temperature flame retardant without deformation, metal paint without rust, effectively preventing high temperature, anti-heavy pressure, and eliminating safety hazards.

Troubleshooting
- Output adjustment seems limited (high loads): Keep short-term adjustment within 3 kW and long-term continuous adjustment within 2 kW.
- LED lighting is not responding to adjustment: LED energy-saving lights are not adjustable with this device.
- Motor speed regulation issues: Check with customer service before adjusting motor settings, since not all motor types support voltage speed regulation.
