Note that the load must be connected before adjusting the voltage.


Thyristors are mainly used for resistive loads (electric heating filament incandescent lamps, etc.). Most single-phase AC motors are also available, but they are not guaranteed. For other types of loads, please confirm by the buyer. The fuse is not omnipotent and has a response time. If the current is too large, in addition to the fuse, the module may also be burned out.

Note that the plastic cover on the connector cannot be completely opened due to the installation of the shell. The screwdriver must be turned 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.
