Important Notes
Use DC power only. Do not connect the module directly to 220V AC mains.
Check the power supply polarity before connecting.
Keep the load current within the 3A rating and ensure adequate cooling where required.
Actual motor speed depends on the motor, load, and supply voltage. A 0% setting may not guarantee complete electrical isolation.
The front knob or connector colour may vary depending on stock availability.
