  • Specification

The IT8500G+ series is designed for high-speed, high-precision testing, making it suitable for testing a wide range of DC loads such as power supplies, fast charging devices, battery-powered products, and solar energy systems. It offers a wide variety of features like arbitrary waveform generation, ripple measurement, and dynamic load testing. The multi-channel mode is especially useful for users requiring simultaneous testing of multiple DUTs (Devices Under Test) with minimal complexity and reduced cost.

The IT8500G+ series includes 8 fast charging protocols to verify performance across a broad range of charging devices. With its list mode, users can simulate complex current waveforms, and the automatic test function ensures fast and accurate testing of various products. Built-in full protection features such as overvoltage protection (OVP) and overcurrent protection (OCP) guarantee safe operation during tests.
