Overview (DJW-WB.SJW-WB single.three-phase microcomputer non-contact compensation power regulator)
SJW-WB, DJW-WB series single-phase and three-phase microcomputer non-contact compensation power regulator (regulated power supply), this regulator is the introduction of international AC stabilized power supply (regulated

A new high-power AC stabilized power supply (regulator) designed with new technology and based on China's national conditions. This regulator (regulated power supply) integrates advanced combined winding compensation methods and

Non-contact switch, microcomputer-controlled AC voltage stabilization technology in one, this voltage stabilizer (regulated power supply) has high efficiency and energy saving, fast adjustment, three-phase automatic balance, no mechanical failure and carbon brush

Wear, this voltage stabilizer (regulated power supply) also has delay, over and under voltage alarm and protection functions. At the same time, the voltage regulator (regulated power supply) breakthroughly solves the problem of system and device operation.

The damage caused by the state process to the common-state current shock and overvoltage produced by the non-contact switch has a strong instantaneous overload capacity, thereby greatly improving the reliability of the regulator system operation.

Selection tips (DJW-WB.SJW-WB single.Three-phase microcomputer non-contact compensation type power regulator)
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 for the reliability of the center line in the system.

When using this voltage regulator (regulated power supply), pay attention to the selection of the cross-sectional area of the neutral line in the system to minimize the contact resistance of the neutral line.
2. When selecting this voltage stabilizer (regulated power supply) product, the load equipment current must not exceed the rated current value of the product; if an inductive motor load is used, its power must not exceed

1/6 of the power of the regulator (regulated power supply).
3. The input and output of this voltage stabilizer (regulated power supply) are not isolated. Please pay attention to prevent static electricity.
