Product Description

Zhengxi's SBW-N series three-phase voltage regulators utilize copper-pillar servo technology and provide military-grade power protection. Designed for manufacturing plants, data centers, and infrastructure projects, these non-inverting regulators maintain ±3% output accuracy even under extreme grid fluctuations. Our solutions are trusted by engineers in 18 countries to prevent six-figure downtime losses in mission-critical operations.

Our Advantages

Unlike relay-based voltage regulators or independent phase systems, the SBW-N series utilizes three-phase unified regulation and precision servo control:
Synchronous Monitoring: Single-point voltage sampling of all phases (200 times/second)
Centralized Correction: A microprocessor calculates correction values for unified regulation
Balanced Output: Maintains 380V, 416V, 400V ±3% or custom voltages without phase separation

SBW high-power voltage stabilizer is designed and manufactured with international advanced compensation technology. When the grid voltage fluctuates or the load current changes, it can automatically keep the programmed voltage stable to ensure the normal
operation of the electrical equipment. Compared with other types of rental voltage stabilizers, It has large capacity, high efficiency , no waveform distorsion, easy to use and maintain, reliable operation, and can still output at full capacity when the input voltage range is low. With over voltage, over current, start up phase sequence and other protection.
