China VTIS Power Supply & Breaker Protection System - Reliable Suppliers & Factory Solutions for Secondary Control

VTIS offers comprehensive protection for the secondary control power supply of circuit breakers, addressing key factors that jeopardize reliability, including voltage fluctuations, interference, lightning overvoltage, and temporary power loss. By preventing these issues, VTIS helps to ensure the normal operation of control systems, thereby safeguarding primary systems and equipment from potential shutdowns or damage.

Designed in China by leading suppliers, VTIS incorporates a parallel oscillation control module and a series interference suppression module. The latter operates continuously in long-term mode, providing reliable protection against various interferences such as lightning overvoltage, ground potential counterattack, operational overvoltage, resonance overvoltage, voltage transients, harmonics, and high-frequency interference. This innovative factory-engineered solution ensures the safe and dependable functioning of secondary systems in challenging environments.
