VTIS Power Supply Protection for Circuit Breakers - Reliable Secondary Control Solutions from China Suppliers and Factory

VTIS is designed to thoroughly safeguard critical elements that jeopardize the reliability of secondary control power supplies for circuit breakers, including voltage fluctuations, electromagnetic interference, lightning overvoltage, and short-term power losses. These issues can hinder the normal operation of control systems, potentially leading to shutdowns or damage to primary systems or equipment. As a leading supplier and factory in China, we ensure that VTIS effectively mitigates these risks.

The VTIS system comprises a parallel oscillation control module and a series interference suppression module. The series interference suppression module operates continuously in a long-term mode, providing persistent protection. It excels in safeguarding secondary control power supplies and circuit breaker secondary circuits from various disturbances such as lightning overvoltage, ground potential surge, operational surges, resonance overvoltage, voltage transients, harmonics, and high-frequency interference. This reliable solution ensures the safe and dependable operation of secondary systems, making it an essential product from a trusted supplier in the industry.
