## Description

Description: Working voltage: AC 220V Regulation voltage: AC 10-220V Max power: 4000W (resistive load) Efficiency: 90% Dimensions: 85 x 55 x 38MM   Note: You must connect to the load before the regulator. SCR is mainly used for resistive loads (incandescent electric wire, etc.) Most of the single-phase AC motor can, but can not guarantee, other types of loads buyer to confirm their own. Fuse is not a panacea, there is reaction time, if the current is too large, in addition to burn the fuse, the module may also be burned. Attention to fitting plastic cover due to the installation of the housing, can not be completely open, screwdriver to tighten the side with the point.  The other to be careful when opened,excessive force easily snapping the lid, express transportation may also crushed for wearing parts, but It does not affect the module.   Package included: 1 x 4000W AC220V SCR silicon controlled electronic volt regulator

## Features

- 【ADVANTAGE】AC 50V-220V continuously adjustable, zero hysteresis, zero latency, superior heat dissipation.
- 【WIDELY APPLICATION】Can be used in many places,such as:furnace,hot water heater tune,dimming lamps,small motor speed,electric iron thermostat and so on,so as to achieve dimming,thermostats,voltage regulating effect.
- 【GOOD SOLUTION TO OVER-CURRENT】Using the new two-way high-power thyristor, current up to 40A, a good solution to the problem of over-current cause by the resistance is too small.
- 【ENOUGH TO USE】For electric power is less than 4000W of large electrical appliances , so the general home appliances or small factories are enough to use.
- 【CONVENIENT】Gently rotate knob cap, can adjust flexibly, do not need to add any element, the product is practical, convenient.
