Electric Motor Variable Speed Controller 120V~220V 15A 4000W AC Motor Speed Controller Variable Voltage Regulator Adjustable Voltage Controller Temperature Adjustment and dimming with Voltmeter About this item: New upgrade: variable voltage fan speed controller, the input voltage is AC 120-220V, the output voltage is adjustable from 0-220V, the maximum power is 4000W, the rated current is 9A and the limit current is 18A Good quality: zero hysteresis, zero delay, with peak voltage absorption circuit to effectively protect high-power thyristor, anti-surge, anti-peak, RC absorption multiple protection. The flame-retardant metal casing does not deform under high temperature, and the metal spray paint does not rest, which is resistant to high temperature and heavy pressure High safety: This voltage regulator adopts imported high-quality chip thyristor, high-power new semiconductor, all-aluminum heat sink, high-temperature-resistant FR-4 circuit board, and double-sided copper-platinum welding is safer and firmer. The multifunctional industrial socket is adopted, and the internal copper parts are thickened phosphor bronze fittings, which have good contact and safety Applicable appliances: Transformer regulators are suitable for electric stoves, water heaters, tungsten lamps, small motors, electric soldering irons, fan speed regulation, etc. Many motors do not support voltage regulation (such as single-phase motors, dual-value capacitor motors, asynchronous motors, pumps, etc.) Note:1. The output voltage measuNote: The inductive load is 1/3 of the resistive load. The resistive load refers to tungsten lamps, heating wires, etc., and the inductive load refers to the series excitation motor. etc. Electronic products with circuit boards should be used with cautionmotor. etc. Electronic products with circuit boards should be used with caution Product Color: Black Input Voltage: AC 120-220V Output Voltage: 10-110V (adjustable) Maximum Power: 4000W Maximum Current: 15A Adjustable Voltage Range: 0-110V Package Contains 1 x Fan Speed Controller
