4000w High power Thyristor 220VAC to10-220VAC

4000w High power Thyristor 220VAC to10-220VAC


In stock (can be backordered)

This 4000w High power Thyristor 220VAC to 10-220VAC is mainly used for resistive loads (electric heating incandescent lamps, etc.), most of the single-phase AC motors are also included, but they are not guaranteed. Other types of loads should be confirmed before use. The 4000W regulator’s voltage regulation range can be smoothly adjusted from 10V-220V, which is more suitable for industrial enterprises that need low-voltage driving heating wire. The fuse is not omnipotent and has a reaction time. If the current is too large, the module may burn out besides burning the fuse.

Note: that the plastic cover on the connector cannot be completely opened due to the installation of the outer casing. your screwdriver should be twisted at a slight angle. In addition, be careful when opening it. If the force is too large, the cover may be easily broken.

Note: that the load must be connected before the voltage is adjusted.
