YCIT-J Series Medical IT Insulation Monitoring Instrument
The YCIT-J Series Medical IT Insulation Monitor uses a high-performance 32-bit ARM processor as its data processing core. It is equipped with a color TFT touchscreen as the human-machine interface, providing users with an intuitive and friendly interaction experience.
Designed specifically for medical isolated power systems, this device monitors IT circuits downstream of the medical isolation transformer in real-time. It displays critical parameters such as insulation resistance, load current, and transformer temperature. When monitored values exceed preset limits, the device triggers audible and visual alarms, allowing medical and technical staff to troubleshoot faults promptly and significantly reducing the risk of electric shock for both patients and healthcare personnel.
Key Features
- Insulation Monitoring: Monitors insulation resistance in both AC and DC isolated power systems.
- Electrical Parameter Measurement: Tracks voltage, current, apparent power, and active power.
- Temperature Monitoring: Monitors the temperature of the isolation transformer (primary and secondary).
- Dual Power Input Monitoring: Monitors voltage for both mains and backup power supplies.
- Advanced Diagnostics: Monitors residual current, output waveforms, and harmonic content (to provide a basis for harmonic management).
- Alarm System: Audible and visual alarms for insulation faults, transformer over-temperature, and system overload/residual current.
- Self-Testing: Includes a built-in self-test and calibration function.
- Communication: Equipped with 2-way RS485 communication ports.
- Display: 2.8-inch TFT color touchscreen.
