product description
SJW-WB, DIW-WB series single and three-phase microcircuit non-contact compensation type power regulators are the latest high-power AC stabilized power supply designed according to the latest technology of international AC stabilized power supply and designed according to my country's national conditions. It integrates advanced combined winding compensation method, non-contact switch, and microcomputer-controlled AC voltage stabilization technology. It has high efficiency and energy saving, fast adjustment, three-phase automatic balance, no mechanical failure and carbon brush wear, and has delay, over and under At the same time, the voltage stabilizer has solved the damage caused by the instantaneous current shock and overvoltage produced by the non-contact switch during the operation state of the system and the device, and the instantaneous overload capacity is strong, thus greatly improving the Reliability of system operation.
Use occasion
Mainly used in communication, medical, textile, radio and television, precision instruments and various elevator systems and other places that require regulated power supply.

Selection Tips
1. This voltage stabilizer (stabilized power supply) product is a three-phase four-wire, split-phase adjustment method. This voltage stabilizer (stabilized power supply) has high requirements on the reliability of the neutral line connection in the system, so this voltage stabilizer is used. (Stabilized power supply) Pay attention to the selection of the cross-sectional area of the neutral line of the system, and minimize the contact resistance of the neutral line.
2. When this voltage stabilizer (stabilized power supply) product is selected, the current of the load equipment shall not exceed the rated current value of the product; if an inductive motor load is used, its power shall not exceed 1 of the power of this voltage stabilizer (stabilized power supply) product. /6.
3. The input and output of this voltage stabilizer (stabilized power supply) are not isolated, please pay attention to prevent static electricity.
