AC Variable Fan Speed Controller, SCR Voltage Controller Fit for Fan Electric Motor Router Rheostat, Variable Voltage Regulator 120V 220V 15A 4000W Max
  • Attributes: This is a variable voltage fan speed controller, the input voltage is AC 120-220V, the output voltage is 10-110V (adjustable), the maximum power is 4000W, the current is 15A, and the adjustable voltage range is 0-110V
  • Powerful Function: The voltage controller has variable thyristor and electronic voltage regulator. The maximum power of connecting inductive loads (such as fans, routers) is about 1500W, and the limit power of connecting resistive loads (such as electric furnaces, heating wires) is 4000W
  • High Security: No delay, surge protection, anti-spike, arc-suction multiple protection, both input and output current are AC, effectively ensuring your safety. The core chip adopts a new type of bidirectional high-power thyristor with a maximum current of 15A, which effectively solves the problem of wire overcurrent when the heat dissipation resistance is too large
  • High-Quality Materials: Our voltage stabilizer adopts imported high-quality chip thyristor, all-aluminum heat sink is suitable for high-temperature circuits, and adopts multi-functional industrial sockets. The copper parts are thicker inside, with high current, good contact and high safety. The fan speed control switch has a power light, and the heat dissipation connector can help quickly dissipate heat and prevent burnout
  • Wide Range of Applications: Our ac motor speed controller can be widely used in fans, electric furnaces, water heaters, small motors, electric irons, tungsten lamps and other electrical appliances. At present, most motors do not support voltage regulation (such as, single-phase motors, asynchronous motors, dual-value capacitor motors, etc.), which are not suitable for smart home appliances with complex circuit boards
