IT2700 Multi-channel Modular Power System

The modules could be bidirectional DC power supplies, DC power supplies or regenerative loads. And they can be connected with each other in parallel. They have built-in LAN, USB, CAN, digital I/O and free PC software. It can be widely used in ATE integration in R&D, design verification and manufacturing of DC-DC converter, communication power semiconductors, 3C products, like smartphone, PCBA, battery simulation and test, chips BMS chips etc.

Functions and Advantages

List sequence

By editing the voltage, current, pulse width and slope of each step, it can generate a variety of complex sequences, help you complete various loading tests and import or export the files.

Multiple operation modes

IT2700 load provides 10 operating modes. In addition to CC, CV, CR, and CP, it also includes 5 compound modes: CC+CR mode, which is often used in OBC voltage limiting, current limiting characteristic tests, constant voltage accuracy, and constant current accuracy tests to avoid OCP of the OBC. The CR+CV mode is used to simulate LED lights, test the LED power supply, and acquires the current ripple. The CP+CV mode can replace the VON point setting or be used for battery discharge testing, and the voltage setting point can be used as the cut-off voltage. CC+CV mode can be used to simulate batteries, test charging piles or chargers, and limit the maximum load current while CV is working. AUTO mode allows it to be automatically switch between CV, CR, CC and CP modes. When the DUT's protection circuit is damaged, the mode can be automatically switched to avoid DUT damage. BSIM (Battery Simulation) mode can output a voltage to simulate a battery for testing chargers and other equipment.

Output on/off serialization

The on/off delay function for each output allows you to serialize the on/off of the output.

Coupling - Channel grouping function

• Grouping with different frames
• Controlled by LAN, no limit of channels
• Control includes setting voltage and current |ON by group | Start a function | Trigger
• Output grouping, protection grouping and stop output grouping (emergency stop grouping) can be set separately

Free PC software

IT2700 comes with free software PV2700 and Web control functions. Both support the Windows 11 operating system. The graphical interface is more intuitive. Using the host computer software is more convenient for oscilloscope display, data recording display, battery simulation and editing of various complex waveforms.
