Product selling point: 1. Double panel design 2. Using 1.6 thick FR-4 high temperature resistant circuit board, the circuit design is reasonable, and the welding circuit design is increased and thickened, even if the large current passes through, it is enough to deal with it, and the use is safer and more reliable. 3. The regulator with housing is safer 4. It is more convenient to install, more suitable for families and factories and enterprises that are inconvenient to install 5. Use imported 41A SCR 6. The circuit has undergone many technical improvements, and each accessory has been selected, and the technology is now fully mature. The dual-capacitor design (safety capacitor + metal film capacitor) can effectively absorb surges and voltage spikes, more effectively protect the thyristor, and the use efficiency is higher and safer. Product Specifications: Product Name: 6000W AC Voltage Regulator SCR model: BTA41600B Knob inner hole 6mm. Without protruding knob Maximum power: 6000W (resistive load limit power) The power should be reduced for a long time, and it is recommended to use the resistive load at room temperature within 3000W Efficiency: more than 90% Working voltage: AC 220V Adjustment voltage: AC 0-220V, under resistive load conditions, the starting adjustment is more than ten volts, and the callback can reach 0. Precautions: 1. This product is AC input and AC output. It can only be stepped down, and the voltage can be adjusted only when it is connected to a load. It is useless to connect a multimeter with no load, not a transformer. 2. The thyristor is mainly used for resistive loads (electric heating wire incandescent lamps, etc.), and most single-phase AC motors can also be used, but they are not guaranteed. For other types of loads, please confirm by yourself.
