Specification: Certification: NONE Origin: Mainland China Phase: single phase Current Type: AC Model Number: Electronic Voltage Regulator Thyristor Model: BTA41600B Maximum Power: 4000w (Resistive Load Limit Power), Long Time Should Reduce The Power To Use, It Is Recommended That Room Temperature Resistive Load 2000w Within The Use (Key Parameters, Please Note) Efficiency: 90% Or More Working Voltage: AC 220v Adjustment Voltage: AC 0-220v, Resistive Load Conditions, Start Adjusting More Than A Dozen Volts, Adjustable Back To 0 Use The Original Imported 41a Silicon Controlled Product Description: 1. The default delivery of this product output is up to 220V 2. For driving low voltage heating wire, the length of only a few centimeters and tens of centimeters, heating wire working voltage is generally a few volts to tens of volts, such as cutting styrofoam  Pearl cotton, raincoat production, branding iron heating, etc., due to the resistance value of only a few ohms dozens of ohms, the use of 220V output, a little carelessness is very easy to burn! 3. Special low voltage version of the regulator, low voltage version of the highest output limit of 50-70V or so, to meet most of the requirements of low-voltage drive occasions 4. Note that although the output is low voltage, absolutely can not touch the hand to prevent electric shock! Note: 1. Note that the load must be connected first and then regulate the voltage 2. Thyristor is mainly used for resistive loads (electric filament incandescent lamps, etc.), most of the single-phase AC motors can also be, but do not guarantee that all can be other types of loads, please buyers to confirm their own! 3. Fuse is not universal, there is a reaction time, if the current is too large, in addition to burning the fuse, the module may also burn out! 4. Note that the plastic cover on the connector due to the installation of the shell, can not be completely lifted off, the screwdriver should be biased point to screw! 5. In addition to lift off with care, too much force is easy to breaking the cover, courier transportation may also be crushed for wearing parts, but will not affect the use of modules 6. With a shell with a fuse regulator safer, easier to install, more suitable for families and inconvenient installation of factories and enterprises 7. 1.6 thick FR-4 high-temperature circuit board, circuit design is reasonable, and increase the thickening of the welding circuit design, even if the high current through the enough to cope with the use of safer and more reliable! 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! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1*Electronic Voltage Governor (Without Fuse Housing)/1*Electronic Voltage Governor (With Fuse Housing)
