The voltage regulation range of 4000W voltage regulator can be truly smooth and adjustable from 10V to 220V, which is more suitable for industrial enterprises that need low voltage to drive the heating wire.

Specifications:

Product name: 4000W ac voltage regulator

SCR model: BTA41600B

Size: 85* wide * 55* high 38mm long, 6mm inner hole of knob.

Maximum power: 4000W (resistance load limit power), long time should be reduced power use.

Efficiency: over 90%

Operating voltage: 220V ac

Regulating voltage: ac 10-220v

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

Thyristor is mainly used for resistance load (electric filament incandescent lamp, etc.), most single-phase ac motors are ok, but not guaranteed, other types of load please confirm by the buyer. Fuses are not omnipotent, there is reaction time, if the current is too large, in addition to the fuses, modules may also burn out.

Note that the plastic cover on the joint cannot be fully lifted due to the installation of the outer shell, and the screwdriver should be slightly twisted. In addition, be careful when lifting the screw, it is easy to break the cover with too much force.

Internal picture:

Voltage regulator size: 85mm long * 55mm wide * 35mm high

With a case with fuse voltage regulator safer, more convenient installation, more suitable for family and inconvenient installation of factory enterprises.

Use original imported 41A thyristor.

With a 1.6-thick fr-4 high temperature resistant circuit board, the circuit design is reasonable, and a thickened welding circuit design is adopted, even if a large current is passed, it is enough to cope with, and it is safer and more reliable to use.

Standard 35A 4 - bit terminal, so that the real design of 4000W. It's more convenient to connect two in and two out.

After many technical improvements, the circuit has been carefully selected for each component, and now the technology is fully mature. Double capacitance design (amperometric capacitance + metal film capacitance) is adopted to effectively absorb surge and voltage sharp front, more effectively protect thyristor, and more efficiently and safely use.

For external use, 1.5-thick aluminum plate and stainless steel die stamping forming, beautiful and generous, more suitable for household temperature regulation speed regulation and industrial enterprises use! Beautiful and generous, safe, convenient, high quality products, from time to time general bare plate voltage regulator can be compared. No matter how long you use it, it won't rust or cause other appearance problems.
