Fast loading with double power

The input voltage of IT8400 DC electronic load can reach 1200V. It has a fast double power loading capacity and is available for all models from 6kW to 600kW. You do not need to select the model according to the maximum power during the actual test, which can greatly save you costs. The input over power and loading time are relevant to the temperature of the electronic load. For example: below 30℃, IT8400 supports double power loading within 3 seconds. This makes it suitable for instantaneous high-power discharge tests of motors and batteries. For example, simulating the starting of a DC motor, simulating the transient overload characteristics of some power supplies, or instantaneously discharging a high-power battery or fuel cell.

Higher current rise and fall speed and dynamic speed

Dynamic testing is one of the necessary test items for power supplies. The dynamic mode of IT8400 can be used to measure it. Set the current level, time, rising and falling slope, and repeat times, and then you can check if the power supply still works stably when the load current is changed stepwise. IT8400 supports the programmable dynamic loading mode with 25kHz. The minimum current rise and fall time is 15us. When the loading current changes continuously, the internal monitoring and circuit can minimize the current waveform distortion. So it is well used for transient response tests of switching power supply and dynamic discharge tests of the battery.

3 Current measurement range

All models of the IT8400 series have 3 current measurement ranges. For example, the 1200V, 6kW model, its current can reach 1.5A. In addition, the high resolution (40uA at most ) and high accuracy (1.5mA at most )
enable it to be widely used in the tests such as solar, power semiconductor devices, automotive electronics, and so on.
