List Sequence

By editing the voltage, current, pulse width and slope at each step, a variety of complex sequences can be generated, allowing the user to complete a variety of tests with carrier waveforms, import or export the edited file.

Multiple operating modes

The IT2700 load is equipped with 10 working modes, in addition to the basic modes CC, CV, CR, CP, it also has 5 composite working modes: CC+CR mode is commonly used in the testing of voltage limiting and current limiting characteristics of on-board chargers, testing of constant voltage accuracy and constant current accuracy, to prevent overcurrent protection of on-board chargers.CR+CV mode is applied to the simulation of LED lamps, testing of the LED source, and measuring the LED current ripple parameter. CP+CV mode can be applied instead of VON point setting or used for battery discharge test, and the voltage setting point can be used as cut-off voltage.CC+CV function can be used for load simulation of batteries, testing of charging piles or on-board chargers, and the CV works at the same time to limit the maximum current of the pull load.AUTO mode can be automatically switched under the limitation of fixed-voltage, fixed-resistance, fixed-current modes and fixed-power modes. AUTO mode can be automatically switched between constant voltage, constant resistance, constant current mode and constant power mode under the limitation. AUTO mode can automatically switch between constant voltage, constant resistance, constant current and constant power modes within the limitations of the constant voltage, constant resistance, constant current and constant power modes.

The unique BSIM (Battery Simulation) mode outputs a voltage to simulate a battery for testing chargers and other devices.

Output on/off serialization

The on/off delay function for each output allows you to set the output on/off sequentially.

Coupling channel grouping function

Free uploader software

IT2700 comes with free software PV2700 and Web control function, both support Window 11 operating system, graphical interface is more intuitive, the use of the upper computer software is more conducive to the oscilloscope display, data logging display, battery simulation and a variety of complex waveform editing
