Topical 1.5 thick aluminum and stainless steel mold stamping forming, beautiful appearance, which is more suitable for the use of the family temperature regulation and speed regulation and industrial enterprises. Elegant, safe, convenient, high quality products, absolutely from time to time the general pressure regulator can. Use the time to be longer and will not rust and other problems.Circuit after many times of technological improvement, selection of each of the parts, has now been fully technical maturity. The double capacitor design (safety capacitor + metal film capacitors) effectively absorb the surge voltage and voltage spike, more effective protection of the controllable silicon, use efficiency and higher safety.The store regardless of the cost, the 4 terminal adopts 35A standard, this really 4000W design. (two to two in a more convenient connection).Use 1.6 thick FR-4 high temperature resistant circuit board, circuit design is reasonable, and the use of increased thickening of the welding circuit design, even if the large current through the use of a more safe and reliable.The use of imported 41A SCR. (fake a lose ten, every product of this store is not Jerry)With the shell with a fuse to adjust the pressure is more safe, more convenient to install, more suitable for family and not convenient for the installation of factory enterprises.Regulator size: length 85mm* width 55mm* height 35mmInternal picture:Note that joint plastic cover due to the installation of the shell, can not be completely opened and a screwdriver to slant little twist, also opened to be careful, excessive force to snapping lid, express transportation also may be crushed and as vulnerable, but does not affect module uses, usually plastic cover issues related to the shop disclaim all responsibility for returned goods.Controllable silicon is mainly used for resistive load (heating wire incandescent lamps, etc.), single-phase AC motor parts can also be, but do not guarantee can be, and other types of load please buyers own confirmation. The fuse is not a panacea, reaction time, if the current is too large, in addition to burn out the fuse, the module may also burn.Attention must be paid to load and then adjust the pressure.Regulator voltage: AC 10-220VWorking voltage: AC 220VEfficiency: 90% aboveMaximum power: 4000W (resistive load limit power), long time should be used to reduce power.Size: length 85* width 55* high 38mm, knob inner hole 6mm.SCR model: BTA41600BProduct Name: 4000W AC voltage regulatorSpecification parameter:
