ITECH IT8500G+ Series Electronic Load: Multi-functional Power Testing Solutions

In the field of power testing, high-efficiency and high-precision equipment is the core requirement for R&D, production and quality inspection. ITECH IT8500G+ series programmable electronic load, with its multiple functions, flexible configuration and excellent performance, provides full-process testing support for scenarios such as fast charging adapters, industrial power modules, battery systems, etc., and has become a reliable choice in the field of power testing.

1. Core Functions: One Instrument Covers Multi-scenario Test Requirements

• Seven Load Modes: Supports 7 operation modes including CC constant current, CV constant voltage, CR constant resistance, CW constant power, etc. It is compatible with load simulation for different DUTs such as adapters, batteries, LED devices, and meets diversified test requirements.

• Built-in Fast Charge Protocols: The IT8511G+ integrates 8 mainstream fast charge protocols including QC2.0/3.0, USB PD2.0/3.0, FCP, SCP and so on. It can quickly verify the no-load voltage, short-circuit current and performance of each charging stage of fast charge devices without external equipment, simplifying the test process.

• Integrated Ripple Measurement: It has a built-in 300kHz bandwidth ripple measurement function, which can directly read voltage/current ripple values (Vpp/Vp+/Vp-, Ipp/Ip+/Ip-). The remote sense function eliminates the influence of line voltage drop, so switching power supply ripple test can be completed without an oscilloscope.

• Dynamic Test and Custom Scenarios: It supports 20kHz high-speed dynamic switching (continuous/pulse/flip mode) to accurately capture the transient response of power supply. The LIST mode can preset 84 steps of complex current change, and synchronize internal and external signals to achieve multi-level loading test, meeting the requirements of strict working condition simulation.

II. Model Selection: Full specifications cover different power scenarios

III. Core Specifications: High Accuracy and Reliability Assurance

• Measurement Accuracy: The accuracy in constant current mode reaches ±(0.05%+0.02% FS), with a resolution as low as 0.1mA; the voltage/current ripple resolution is 0.1mV/0.1mA, which meets the requirements of micron-level signal measurement.

• Safety and Convenience Design: Equipped with OCP overcurrent protection and OCP overpower protection; the battery discharge mode supports setting three thresholds for cut-off voltage, capacity and time to ensure test safety; the I-Monitor terminal on the back panel outputs 0-10V current analog signal, which can be used with an ordinary oscilloscope to monitor the current waveform in real time; the Measure function can measure voltage rise/fall time with one click, and its efficiency is comparable to that of a professional oscilloscope.

IV. Application Scenarios: Adapt to the whole process from R&D to mass production

• Fast Charging Device Testing: Quickly trigger fast charging handshake via built-in protocols, combine LIST mode to simulate real load changes, and verify the stability and compatibility of multi-gear output.

• Battery System Testing: The constant current discharge mode monitors battery voltage, discharge time and discharged capacity in real time, which is suitable for performance evaluation and safety testing of lithium-ion battery protection boards and energy storage battery packs.

• Industrial Power Verification: High-voltage models support 600V input, which meets the testing requirements of high-voltage scenarios such as photovoltaic inverters and rail transit power supplies, and the ripple measurement function effectively evaluates electromagnetic compatibility (EMC).

• Automated Production Line Integration: The multi-channel cascading solution supports large-scale load testing, is suitable for batch quality inspection on production lines, and improves testing efficiency and consistency.

V. Partnership Value: Helping Customers Improve Testing Efficiency

1. Integrated Functions: A single unit integrates functions including protocol testing, ripple measurement and dynamic loading, which reduces the procurement of external devices such as oscilloscopes and protocol analyzers, and cuts down equipment costs as well as wiring complexity.

2. Flexible Application Scenarios: It provides full-coverage solutions for all scenarios, ranging from low-power fast charging to ultra-high power industrial power supply, from stand-alone laboratory testing to automated production lines with up to 16 units cascaded.

3. Reliable Brand: As a world-renowned power testing brand, ITECH products have passed strict certifications. We have a nationwide technical support and after-sales service network to provide users with long-term and stable operation guarantee.
