Three Phase No Contact Fully Automatic Intelligent Static Voltage Regulator 100Kva-4000Kva

A Three-Phase No-Contact Fully Automatic Intelligent Static Voltage Regulator (100 kVA–4,000 kVA) is a high-performance, solid-state static voltage stabilizer built to deliver instantaneous, distortion-free voltage regulation for large industrial sites and mission-critical installations. Unlike electromechanical stabilizers, the no-contact static regulator uses power-electronics (SCRs/IGBTs, fast electronic control and transformer compensation) to correct supply voltage in milliseconds — with no moving parts, near-zero mechanical wear, and extremely low maintenance.

The ZBW static stabilizer is the go-to solution when the grid suffers frequent sags, swells, unbalanced phases or harmonic disturbances, and when equipment sensitivity (PLCs, CNCs, medical imaging, instrumentation) demands the cleanest possible power.

Product Advantages

Real-time Voltage Monitoring
The static voltage regulator constantly keeps an eye on the three-phase input power and makes instant electronic adjustments to keep the output stable within a narrow, preset range.

Fast Digital Control
Equipped with high-speed ADC sampling and advanced digital control, the system can detect and correct voltage fluctuations in just milliseconds, ensuring reliable performance.

No Mechanical Switching
Using SCR/IGBT power modules or a PWM control stage, the regulator adjusts the voltage electronically — no mechanical taps, no wear and tear, and longer service life.

Clean, Stable Output
A built-in compensation transformer and filter ensure a pure sine wave output, keeping the waveform clean and free from additional distortion.

Smart Protection & Easy Control
Features include a touchscreen HMI, bilingual interface, automatic bypass, and remote monitoring, making the system simple to operate and highly secure.

Contactless, Precise Regulation
The non-contact design ensures spark-free, smooth, and precise voltage control, making it perfect for high-precision industrial equipment and sensitive electronics.
