For other types of loads, please confirm by the buyer. _x000D_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. _x000D_Note that the plastic cover on the connector cannot be completely opened due to the installation of the shell. The screwdriver should be turned slightly. _x000D_In addition, be careful when opening it. Excessive force will easily break the cover. _x000D_ _x000D_Specification: _x000D_Item: 4000W AC voltage regulator _x000D_Thyristor model: BTA41600B _x000D_Size: length 85*width 55*height 38mm, inner hole of knob 6mm. _x000D_Maximum power: 4000W (resistive load limit power), the power should be reduced for a long time. _x000D_Efficiency: more than 90% _x000D_Working voltage: AC 220V _x000D_Regulating voltage: AC 10-220V _x000D_ _x000D_Note: _x000D_Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x000D_Please allow 1-2cm measuring deviation due to manual measurement. _x000D__x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1 X Voltage Regulator _x000D__x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ [relateproductdetail/]_x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
