VTIS: China Suppliers for Secondary Control System Power Supply & Breaker Protection Factory

VTIS is an advanced protection solution designed to safeguard the secondary control power supply for circuit breakers from various reliability issues, such as voltage fluctuations, interference, lightning overvoltage, and short-term power loss. This comprehensive system helps prevent control system failures, thereby avoiding potential shutdowns or damage to primary systems and equipment caused by these issues. As a leading product from a reputable factory in China, VTIS ensures high-quality performance.

The VTIS system comprises a parallel oscillation control module and a series interference suppression module. The series module operates continuously in a long-term mode, effectively mitigating disturbances from lightning overvoltage, ground potential surges, operational overvoltage, resonance overvoltage, voltage transients, harmonics, and high-frequency interference. Our reliable product ensures the safe operation of secondary systems, making us a preferred choice among suppliers in the industry.
