The biggest feature of the product is that the built-in brushless fan has good heat dissipation Product parameters
Product Name: 4000W AC Voltage Regulator Thyristor Model: BTA41-800B Size: length 100 * width 40 * height 68mm, knob inner hole 6mm.
Output power: 4000w (resistive load limit power), power should be reduced for a long time, it is recommended to use room temperature resistive load within 2000w. Efficiency: more than 90%. Net weight: 145 grams
Operating voltage: AC 220V Adjust voltage: AC 0-220V (under resistive load, the starting adjustment of more than 10 volts and the callback can be zero volts)
Note: The measured voltage under the load must be turned on first, and the no-load voltage remains unchanged The product is mainly used for resistive loads (such as electric furnace wire, white banner lamp, etc.)
