Voltage Regulators 4000w 220v High Power Scr Speed Controller

How to use: Connect the input of this product to 220V AC, and connect the output to the electric furnace wire or electrical appliance, and rotate the potentiometer to adjust the speed, voltage and temperature; it is very convenient to use.Precautions:Note that the load cannot exceed the specified maximum power, otherwise the modules and electrical appliances will be burned; try to use resistive loads; the power of inductive and capacitive loads should be greatly reduced (it is better to leave more than half of the load).Use voltage: AC 110V-220VMaximum power: 4000W (connected to resistive load)Voltage regulation: adjustable between AC 0-input voltageThis product is suitable for: using a new type of bidirectional high-power thyristor, because the maximum design current can reach 20 amps, it solves the overcurrent problem caused by too small resistance of the electric furnace wire when it is cooled; it can be easily adjusted The output voltage of the mains can be adjusted arbitrarily between 0 and 220 volts for electrical appliances. Such as: electric furnace, heat adjustment of water heaters, light adjustment of lamps, speed adjustment of small motors, temperature adjustment of electric irons, etc. So as to achieve the effect of dimming, temperature regulation and pressure regulation. It can be used for large electrical appliances with a power consumption of less than 4000 watts. Since the power is already large, it is sufficient for general household appliances or small factories. (The power of the inductive or capacitive load should be reduced. The voltage regulator is equipped with bidirectional high-power thyristor, the potentiometers are all equipped with nuts, and are equipped with a thick aluminum shell and a large radiator. It can be used without adding any components. Convenient and practical).Size: 91MM x width 59MM (without handle) total height 34MMModel: ZS-PA4000AColour:As shownMaterial:MetalPackage Contents:1 x Voltage RegulatorsOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
