Features:

Adopts double insulation; there will be no electric leakage if short-circuit or SCR burn out.

Can prevent peak voltage and electrical surge; RC absorption and fuse enhance usage safety.

Aluminum case prevents it from easy damage; filled tin prevents it from heating when in huge current.

With protective cap and connection post; thicker and larger heat sink.

Wide application: electric furnace, water heater, lamps, small motor, electric iron etc.

How to use:

Adjustable Power Supply Board; connect this device with lamp or home appliance or electric circuit, then rotate the knob for dimming, speed, voltage, temperature control.

Some Applications:

Electric furnace, water heater, lamps, small motor, electric iron etc.

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.
