Itech IT8100A/E Ultra Dynamic High Power DC Electronic Loads

The Itech IT8100A/E series is designed for modern power electronics testing where extremely fast response times, high power levels, and maximum flexibility are essential. This new generation of electronic loads combines a graphical touchscreen, powerful measurement functions, and exceptionally high power density. With power ratings ranging from 2 kW to 86.4 kW per unit and scalability up to 1.8 MW via optical master-slave coupling, the IT8100E/A offers a future-proof solution for R&D, validation, and production.

The series is available in 60V, 150V, 600V, and 1200V models. The maximum power output depends on the voltage. For the 150V models, this is 7.2 kW/3U, and for the 600V and 1200V models, it is 6 kW/3U. This allows for up to 12 units (72 kW or 86.4 kW) in a 37U 19-inch system. Multiple 19-inch systems can be linked via a master/slave setup to reach up to 1.8 MW without synchronization issues or additional noise. The 60V model is available in 2, 4, or 6kW versions with a maximum current of 800A, 1600A, and 2400A, respectively. The minimum operating voltage of 0.24V at 2400A makes the series suitable for testing fuel cells, low-voltage batteries, and modern semiconductors.

Advanced dynamic features for realistic load testing

The IT8100A/E series excels in dynamic performance. With a current slew rate of up to 150 A/µs per unit and a transient frequency of up to 50 kHz, even the fastest dynamic loads can be tested.

Extensive operating modes and simulation functions

The IT8100A/E supports all classic load modes such as CC, CV, CR, CP, and CE, but also offers a range of combined modes (CC+CR / CR+CV / CC+CV / CP+CV / CC+CR+CV+CP) for realistic simulation of complex loads. The A version also features CE/CC sine/CC Pulse/Table modes.

The series also offers advanced features such as LIST programming, OCP/OPP tests, short-circuit mode, and user-defined waveforms. Users can import or define up to 1,000,000 points, making the IT8100A/E suitable for complex real-world waveforms.

Advanced Testing

The IT8100A/E features an extensive battery discharge mode, with support for CC, CR, and CP discharge. Users can set cutoff criteria based on voltage, capacity, time, or energy, while real-time monitoring of voltage, time, and Ah/Wh values is available.

The Sequence function allows different waveforms—such as sine, pulse, ramp, and user-defined—to be combined into a single continuous test program.
The Sweep function supports linear and logarithmic sweeps of voltage or current, ideal for I-V characterization of semiconductors and power modules. Pulse sweeps reduce self-heating and improve measurement accuracy.

The IT8100A/E models can deliver up to 1.5× the rated power for up to 60 seconds (at an ambient temperature of <25 °C). The A models even have a transient capacity of 4× the rated power for 1 msec.

The load supports USB, LAN, and CAN as standard interfaces, with optional RS-232, GPIB, and analog expansion cards.

Applications in modern power electronics

The IT8100A/E series is used worldwide for testing EV charging stations, fuel cells, AI server power supplies, power modules, semiconductors, solar arrays, UAV systems, and smart manufacturing equipment. Thanks to the combination of high speed, high accuracy, and extreme scalability, the series is suitable for both R&D laboratories and large-scale validation and production lines.
