Operating Modes

The IT2700 load offers 10 operating modes. In addition to CC, CV, CR, and CP, it also includes 5 composite modes: CC+CR mode, which is often used in OBC voltage limiting, current limiting characteristics, constant voltage, and constant current accuracy tests to avoid OCP of the OBC. CR+CV mode is used to simulate LED lights, test LED power supplies, and detect current ripple; CP+CV mode can replace the ON point setting or be used for battery discharge tests, and the voltage set point can be used as the shutdown voltage. CC+CV mode can be used to simulate batteries, test charging stations or chargers, and limit the maximum load current during CV operation. AUTO mode allows automatic
switching between CV, CR, CC, and CP modes. If the protection circuit of the device under test is damaged, the mode can be switched automatically to prevent damage to the device under test.
In BSIM mode (battery simulation), a voltage can be output to simulate a battery for testing chargers and other devices.
