FAQs
Q: Can I use this to control an AC fan speed?
Yes, it is suitable for AC brush-type motors such as fans. Not suitable for AC induction motors.
Q: Does it include a cooling fan?
No, cooling fan must be installed separately if load exceeds 10 amps for prolonged use.
Q: Can I use this with LED lamps?
It is not ideal for LED lighting as LEDs require constant current drivers. It works best with resistive loads.
