Specifications:
Product Name: 4000W AC voltage regulator
Maximum power: 4000W (resistive load limit power), long time should be reduced power use. Long time resistance load recommended within 2000.
Efficiency: more than 90%
Working voltage: AC 220V
Adjust the voltage: AC 10-220V
Voltage adjustment range: AC 0-220V, Resistive load conditions, starting a dozen volts, callback can be 0
Note that the load must be connected before it can be regulated
SCR is mainly used for resistive load (electric wire incandescent lamp, etc.), single-phase AC motor can also be, but not guaranteed can, other types of load, please confirm by yourself
Fuses are not omnipotent, there is reaction time, if the current is too large, in addition to burning the fuse, the module may also burn out.

Some Application:
Electric furnace, water heater, lamps, small motor, electric iron etc.Attention:
Load does not exceed the maximum power, otherwise it will burn module and electrical appliances;
use the resistive load as far as possible; reduce inductive and capacitive load power greatly.
( it is best to leave more than half of them)

Type:
Governor/Regulator/Motor speed controller/Dimmer Module

Package Included:
1 x AC 220V 4000W SCR Voltage Regulator Dimmer Motor Speed Controller Module

2000W AC Motor Speed Controller 50-220V 2 Adjustable Motor Speed Controller Voltage Regulator

Description:
This controller uses novel bi-directional high-power SCR. It can be very convenient adjust the current up to 2, and solve the over current problem of the heating wire resistance is too small in the case of cooling causing good.
The output voltage is adjusted anywhere between 50V-220V for use with electrical appliances. It can use to such as electric stove, water heater tune thermal, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect.
