3. Core Product Advantages

The 3500/15-04-00-00 low-voltage DC power supply module delivers outstanding stability and safety as the core power guarantee for 3500 rack systems. Adopting professional DC voltage conversion and filtering technology, it effectively suppresses power grid surge, high-frequency clutter and voltage jitter, providing pure and stable working voltage for high-precision signal acquisition modules and avoiding data distortion caused by power interference. Equipped with comprehensive over-voltage, under-voltage, over-current and short-circuit protection mechanisms, the module can automatically cut off output and trigger fault alarm in case of abnormal power supply, protecting expensive monitoring modules from burnout damage. It supports flexible single-power independent operation and dual redundant hot backup deployment; dual-power mutual backup realizes non-interrupt power supply, completely eliminating system downtime caused by single power failure. The half-height compact structure saves rack space, and the industrial-grade wide-temperature design adapts to harsh on-site environments, ensuring 7×24-hour uninterrupted stable power supply for the entire machinery protection system and greatly improving the overall operational reliability of TSI systems.

4. Industrial Application Scenarios

The 3500/15-04-00-00 low-voltage DC power module is widely applied in industrial scenarios with independent DC power distribution systems and high power supply reliability requirements. In thermal power plant turbine TSI monitoring racks, it provides stable DC power support for full rack monitoring modules, ensuring continuous and accurate collection of turbine vibration, displacement and phase signals during unit load switching and power grid fluctuation. In petrochemical, natural gas and refining industries, it matches explosion-proof and intrinsically safe monitoring systems, adapting to low-voltage DC power supply standards in hazardous areas and meeting site safety specification requirements. It is also commonly used in metallurgical heavy industry, wind power equipment and large rotating machinery monitoring systems with UPS DC backup power systems, serving as a reliable core power unit for industrial automation monitoring racks, avoiding equipment protection failure and data loss caused by power supply abnormalities.
