Three-range Design for High-precision Measurements
The IT8100A series is equipped with three voltage and current ranges, ensuring high-precision measurements across the entire range from light load to full load current. The measurement accuracy remains consistent, whether used as a single unit or in parallel.
High-speed Dynamic Load
The IT8100A Series delivers high-speed dynamic load testing up to 50 kHz, with dynamic current (CCD) and dynamic resistance (CRD) modes. With a current slew rate of up to 150 A/µs and a minimum response time of 8 µs, it accurately simulates rapid load variations for testing AI servers, switching power supplies, and other high-performance power systems.
Electrochemical Impedance Spectroscopy (EIS) Analysis Function
The IT8100A Series features a built-in EIS (Electrochemical Impedance Spectroscopy) function for evaluating battery resistance characteristics and gaining deeper insight into internal performance. With multi-frequency excitation from 0.01 Hz to 20 kHz, it captures subtle responses and helps identify issues that conventional methods may miss. Results are displayed through built-in Bode and Nyquist plots, making it ideal for performanceand lifetime evaluation of fuel cell stacks, active devices, and other electrochemical systems.
1.5x Short-time Overload Capability
The IT8100A series electronic load supports up to 1.5× short-time overpower. At ambient temperatures below 25°C, the overpower can be sustained for up to 60 seconds, effectively covering transient peak power demands during testing. This enables system sizing based on typical operating power rather than peak power, meeting the requirements of power modules, battery packs, and other devices under surge and extreme operating conditions. The front panel displays the allowable overpower limit in real time and dynamically updates it according to the internal thermal conditions, ensuring safe, reliable, and fully observable operation. Leveraging the short-time overpower capability, the system meets high dynamic testing requirements without the need for higher-rated equipment, thereby reducing overall test system cost.
