Product name: 4000W AC voltage regulator
Thyristor model: BTA41600B
Size: length 85*width 55*height 38mm, inner hole of knob 6mm.
High power: 4000W (resistive load limit power), the power should be reduced for a long time.
Efficiency: more than 90%
Working voltage: AC 220V
Regulating voltage: AC 10-220V

Note that the load must be connected before adjusting the voltage.
Thyristors are mainly used for resistive loads (electric heating filaments, incandescent lamps, etc.). Most single-phase AC motors can also be used, but they are not guaranteed. For other types of loads, please confirm by the buyer. The fuse is not. It has a response time. If the current is too large, the module may also be burned out in addition to the fuse.

Note that the plastic cover on the connector cannot be completely opened due to the installation of the shell. The screwdriver must be twisted slightly. In addition, be careful when opening it. Excessive force may break the cover. The express transportation may also be crushed. It is a vulnerable part. It will not affect the use of the module. We are not responsible for the return or exchange of any plastic cover related problems.

The circuit has undergone many technical improvements, carefully selected every accessory, and is now fully technically mature. The use of dual capacitor design (safety capacitor + metal film capacitor) effectively absorbs surges and voltage spikes, more effectively protects the thyristor, and is more efficient and safer.

External use 1.5 thick aluminum plate and stainless steel open die stamping forming, beautiful and generous, more suitable for family temperature and speed adjustment and industrial enterprises! Beautiful, safe, convenient, high-quality products, generally comparable to bare-board voltage regulators. No matter how long it is used, it will not rust and other appearance problems.
