Itech IT2705 Modular DC Power Analyzer

The Itech IT2705 is an advanced modular DC power analysis platform designed for modern R&D environments where accurate power analysis, dynamic waveform recording, and flexible test configurations are essential. The system combines programmable DC sources, bidirectional power supplies, regenerative electronic loads, and SMU modules in a single integrated 5U frame. As a result, the IT2705 replaces multiple discrete measurement instruments and provides a uniform, efficient, and highly accurate test environment. With support for up to eight modules and a wide range of power ratings from 20 W to 500 W per channel, the IT2705 is suitable for a variety of applications such as IoT devices, automotive electronics, semiconductors, DC-DC modules, RF modules, and medical electronics. Thanks to its high sampling rate, built-in data logging, and powerful waveform generator, even the smallest transients and dynamic events can be accurately captured.

Modular design for maximum flexibility

The heart of the IT2705 is its modular design. The 5U frame supports up to eight modules, which can be freely combined. This allows a single system to function as a power supply, electronic load, SMU, battery simulator, and waveform generator simultaneously. Each module operates electrically isolated and can be configured separately, making the system ideal for multi-channel testing or parallel power expansion.

The IT2705 supports four main types of modules:

> IT271XX DC Power Modules
Programmable DC sources with CV/CC/CP modes, fast response, and high accuracy.
> IT273XX Bidirectional DC Modules
Suitable for energy storage, battery simulation, and bidirectional DC-DC testing.
> IT275XX Regenerative Electronic Loads
Support CC, CV, CR, CP, and composite modes, including dynamic load and ARB output.
> IT278XX SMU Modules
Four-quadrant modules for low power, ideal for IoT chips, sensors, and semiconductors. The IT27814 also includes integrated EIS functionality.

Thanks to this modular design, the IT2705 can grow with future testing needs and be easily upgraded.

Advanced Measurement and Analysis Functions

The IT2705 is designed to provide insight into complex electrical phenomena. The system features a 7-inch color display with real-time display of voltage, current, and power. Users can choose from different display modes, including single-channel, four-channel, and eight-channel overview.

Oscilloscope mode
All modules support a sampling rate of up to 200 kSa/s. This allows fast transients, switch-on phenomena, noise, and dynamic load changes to be accurately recorded without external probes. The front panel controls include direct oscilloscope buttons such as trigger, single capture, and run/stop, making operation intuitive.

Data logging
The IT2705 features a powerful data logger that can record voltage, current, and power at intervals as short as 20 microseconds. Data can be stored in internal memory or on USB storage. This makes the system suitable for long-term trend analysis, fault detection, and performance comparisons.

Extensive Waveform Generation and Test Automation
The IT2705 supports multiple advanced output modes that are normally only available in specialized equipment.

LIST Mode
This allows precisely defined steps in voltage or current to be performed, each with an adjustable duration and rise rate. LIST files can contain up to 2000 steps, ideal for simulating start-up profiles, load jumps, or voltage variations.

Arbitrary Waveform (ARB)
ARB output allows users to generate complex waveforms such as sine, pulse, trapezoid, exponential, ramp, or fully user-defined profiles. This is particularly useful for testing DC-DC stability, communication modules, and battery behavior.

Sequence mode
This allows different waveform segments to be combined into a single test program. This makes it possible to simulate realistic scenarios, such as a DC-DC converter transitioning from normal operation to fault conditions.

Const Dwell Arbitrary (CDARB)
In this mode, up to 8000 data points can be imported, each with a fixed dwell time. This is ideal for reproducing measured battery profiles, RF power variations, or complex load patterns.

Battery Simulation and Energy Storage Testing
The IT273XX and IT278XX modules support advanced battery simulation. This mimics the behavior of a real battery based on parameters such as open-circuit voltage, internal resistance, and capacity. The output voltage dynamically adjusts based on the current demand of the DUT, allowing realistic charge and discharge scenarios to be tested without the limitations of physical batteries. In addition, the IT2705 supports comprehensive charge and discharge testing with adjustable cutoff criteria such as voltage, current, time, energy, or capacity. The data logger allows complete charge and discharge curves to be stored and analyzed.

EIS – Electrochemical Impedance Spectroscopy
The IT27814 SMU module includes integrated EIS functionality, which can be used to measure impedance spectra of batteries, fuel cells, inductors, and other electrochemical or reactive components. The module supports frequencies from 0.1 Hz to 20 kHz and automatically generates Bode and Nyquist plots. This makes the instrument particularly valuable for research into battery aging, internal resistance, and dynamic properties.

Applications

The IT2705 is designed for a wide range of test scenarios. The most important applications are explained in detail below.

IoT devices and wearables
IoT devices have extremely low quiescent currents and fast peak currents when communicating or activating sensors. The IT2705 can accurately measure these transients thanks to its high sampling rate and SMU modules with automatic current ranges. This allows designers to optimize energy consumption and predict battery life.

DC-DC modules
In DC-DC testing, the IT2705 acts as both a power supply and a load. Oscilloscope mode captures turn-on behavior, stability, and transient response, while ARB output simulates voltage dips, noise, and variations. This makes the system ideal for complete characterization of converters.

Semiconductors and power ICs
The SMU modules offer accurate four-quadrant control, enabling characterization of diodes, MOSFETs, ICs, and sensors. Thanks to their fast response, even short pulse loads can be measured.

RF modules and communications electronics
RF modules often exhibit rapid variations in power consumption during transmit and receive cycles. The IT2705 can accurately track these variations and correlate them to waveforms, which helps optimize power management.

Medical electronics
Portable medical devices require accurate power analysis to ensure reliability and safety. The IT2705 can perform long-term data logging and simulate battery behavior, which is essential for certification and quality control.

Batteries and energy storage
With battery simulation, charge/discharge testing, and EIS analysis, the IT2705 is a complete platform for battery research, from cell characterization to pack validation.

The Itech IT2705 Modular DC Power Analyzer is a powerful, versatile, and future-proof platform that combines multiple instruments into a single modular system. Combining power supply, load, SMU, waveform generator, oscilloscope, and data logger, it offers unmatched efficiency in R&D environments.
