AC 220V 4000W SCR Voltage Regulator Dimming Dimmers Motor Speed Controller Thermostat Electronic Voltage Regulator Module

The output is recommended not to short circuit, you must connect the load first, and then adjust the voltage! It is recommended to be within 2000W Product parameters: Product name: 4000W AC voltage regulator SCR model: BTA4 1600B Size: length 85*width 55*height 38mm, knob inner hole 6mm. Maximum power: 4000W (resistive load limit power), the power should be reduced for a long time Efficiency: 90% or more Working voltage: AC 220V Regulation voltage: AC 10-220V Note that the load must be connected before adjusting the voltage. For the first time, adjust the potentiometer counterclockwise to bottom. Otherwise, the load such as a small resistance heating wire is connected, and it is easy to burn out at the moment of power-on Thyristors are mainly used for resistive loads (electric filament incandescent lamps, etc.), most of single-phase AC motors It is also possible, but it is not guaranteed. For other types of loads, please confirm by the buyer. Fuse not It is omnipotent and has a reaction time. If the current is too large, in addition to burning the fuse, the module can also Can burn out. Note that the plastic cover on the connector cannot be fully opened due to the installation of the housing, and the screwdriver should be biased. Tighten it, and be careful when lifting it, too hard to break the lid, express delivery is also possible Crushed, as a wearing part, but will not affect the use of the module, thank you for your understanding. Package: 1 x 4000W AC220V SCR silicon controlled electronic volt regulator
