Maximize the Return of Your Test Equipment

With ITECH's exclusive building-block approach: easily configure up to 8 load modules and 16 channels.

Engineer's first choice in multi-channel testing.

Traditional DC Electronic Loads Aren't Built for Flexibility

Stop letting big brand names tell you that "there's a system for that" and paying for outdated technology you don't need.

Our modular design breaks through the traditional testing system limitations, allowing you to configure & build test platform according to your own test requirements.

IT8700 series programmable DC electronic load adopts removable modules design, with single frame control 8 channels, and 16 channels with extended mainframe extension transient mode up to 25 kHz , which improves your test efficiency, with high resolution and accuracy. Users can freely choose in the 8 load modules according to the number of channels and power requirements, controlled by mainframe control panel, or controlled by IT9000-PV8700 software via built-in LAN / RS232 / USB / GPIB interface. IT8700, with adjustable slope, list function, automatic test and other functions, automatic test function can be set to work under CC / CV / CR / CP can be used in the application of R&D and production line. IT8700 has self-diagnosis and comprehensive OVP, OCP, OPP, OTP, etc., ensure the operator safety.

Easily Configurable Modular System

IT8700 adopts modular design, which has a high-performance microprocessor in every module and mainframe. It has high measurement speed because of parallel architecture. The mainframe controls each models synchronously and show the testing values in real time.

Dynamic Power Distribution Function

Usually, one module require high power while another require low power in battery testing. IT8722/IT8722B has dynamic power distribution function,that means within 300W,any channel which power over 50W and less than 250W,the power can be distributed freely, one module can be used as multiple standard modules.

Dynamic Power Distribution Function

ITS5300 battery test system can be formed by IT8700, ITECH power supply, battery resistance tester and temperature data logger, which makes hundreds of channels run at the same time, record voltage and current waveforms in real-time. Test data can be exported to EXCEL.

IT8700 can also equip with ITECH AC and DC power supply, relay card, I/O Card, DSO card to set up ITS9500 power supply test system, which achieves multi-supply modules simultaneously test or multiplex output AC / DC or DC / DC power supply module test.

IT8700 with IT9380 software can achieve multi-channel solar cell test, the test interface can be switched freely, support the sampling time settings, export test data, and with up to 50KHz I-V sampling rate, achieving high efficient and fully automated testing for solar panel.

Peak Voltage, Peak Current Measurement

Dynamic current testing of switching power supply often requires oscilloscope to capture instantaneous voltage and current waveforms to obtain the valve of the peak voltage Vpk and the peak current Ipk. IT8700 is with digital data acquisition function, users can easily get the values of Vpk and Ipk without oscilloscope.

High Resolution and Accuracy

IT8700 has the best product features with 0.1mV / 0.01mA resolution and 50kHz measurement speed, so that your test is fast and accurate.

High Power Density

Maximum power density - 600W single module with ITECH advanced cooling technology, making IT8700 has ultra-high power density, 4U height up to 2400W.

Auto Test

This function can be applied in the automated production test, users can set measurement mode and pull load value of each step for panel or PC software, and the upper and lower limits of test parameters, and display whether the test results have exceeded the set specifications.

PC Communication Interface

IT8700 series of electronic load provide IT9000 PC software, users can easily set and monitor voltage & current waveform of each channel and operation of test, simplify automatic test and battery charge & discharge test. IT8700 has built-in GPIB / Ethernet / USB / RS232 interface, support SCPI communication protocol, provide LabVIEW driver to help customers achieve system structures and remote control.
