1. The FM series resonance withstand voltage testing device demonstrates exceptional stability and reliability. At its core lies an advanced power conversion system utilizing premium imported components, ensuring consistent voltage and frequency outputs. The device features meticulous electromagnetic compatibility design and robust protective mechanisms. Even after numerous high-voltage direct-ground short-circuit tests, the system remains unscathed, showcasing its remarkable durability and overload capacity.
2. The auto-tuning feature is highly efficient. During the automatic tuning process, the system sweeps the frequency range from 30Hz to 300Hz, displaying the sweep curve in real time. This allows users to visually monitor the tuning procedure. Once the sweep concludes, the system precisely identifies the resonant frequency within ±5Hz, conducting a fine scan with a resolution of 0.01Hz before locking onto the exact resonant frequency.
3. Multiple testing modes are supported, including "auto tuning + manual voltage adjustment," "auto tuning + auto voltage adjustment," and "manual tuning + manual voltage adjustment." It is recommended to use the "auto tuning + manual voltage adjustment" mode for quick identification of the resonance point while offering enhanced safety through manual pressure adjustments during the test.
4. The user interface is designed for optimal interaction. Parameters, controls, and results are clearly displayed on the screen, providing intuitive visuals with automated timing and step-by-step instructions. The full touchscreen operation allows for easy data storage and retrieval, enhancing usability.
5. Comprehensive protection mechanisms are integrated into the system. Zero-position protection ensures the system cannot operate unless the voltage output control knob is at zero. Overvoltage, overcurrent, and flashover protections further ensure operational reliability, safeguarding both the equipment and users.
After extensive field testing, this device has proven itself as a dependable tool for high-voltage testing applications. Its combination of precision engineering, user-friendly design, and robust safety features makes it a standout choice for professionals requiring accurate and safe testing solutions.
