VTIS Secondary Control System Power Supply & Breaker Protection - Trusted China Suppliers & Factory Solution

VTIS is an essential solution for safeguarding the reliability of secondary control power supplies in circuit breakers, effectively addressing critical issues such as voltage fluctuations, electrical interference, lightning overvoltage, and short-term power loss. By mitigating these factors, VTIS ensures that control systems operate smoothly, preventing potential shutdowns or damage to primary systems and equipment. As a trusted product among China suppliers and factories, VTIS integrates a parallel oscillation control module with a series interference suppression module, which operates continuously to maintain optimal functionality. This robust series module provides long-term protection against a variety of disturbances, including lightning overvoltages, ground potential surges, operational overvoltages, transient voltages, harmonics, and high-frequency interference. By utilizing VTIS, you can guarantee the reliable and safe operation of your secondary systems.
