IT8300 Series Regenerative DC Electronic Load

High power density

IT8300 series regenerative DC electronic load adopts high power density design, e.g. for 3 U size unit can sink power up to 10.5 kW. Compared with traditional electronic loads, the size of IT8300 series has been reduced by 76.9%.

Regenerative DC electronic load

IT8300 can not only simulate various characteristics of load , but also recover energy back to utility


Regenerative efficiency Max. 95%

Energy-regenerative efficiency Max. 95%

IT8300 series uses the power electronic transformation

technology on the premise of completing test power

experiment to make output energy of measured power supply

regenerative recycled and reused. This way of energy

regeneration helps to lower energy costs and avoids

expensive cooling systems.

Dynamic test function

IT8300 series regenerative DC electronic load provides dynamic test function under CC mode. Electronic load switches between two preset current, which is used to test dynamic characteristics and stability of power supply between different loading current. Dynamic testing mode has three working modes: continuous mode, pulse mode and toggle mode.


Battery test function

IT8300 series simulate battery discharge test in the CC mode

• Support setting discharge cut-off conditions, such as cut-off voltage, cut-off capacity and cut-off time

• When any of the three conditions is met, the discharge will be cut off.

• The battery voltage, discharge time and the discharged capacity can be observed during the test, which reflects the

reliability of the battery and its remaining life.

List function

IT8300 series regenerative DC electronic load provides list mode, which can complete complex arbitrary current change and synchronize with internal or external signals to complete multi-level loading test. By editing the step value, pulse width and the slope of each step, IT8300 can generate a variety of complex sequences and help users to complete various loading waveforms test. In the CC mode, IT8300 series can set rising and falling speed.


Full protection function

IT8300 series can detect the grid state automatically. When grid connection is detected disconnected or power down, IT8300 will turn off immediately, which is also known as anti-islanding protection. For reliable on-grid function, IT8300 has complete ACP protection on the AC terminal: UVP, OVP, UFP, OFP, OCP.

IT8300 also provide complete protection on DC input end: OCP, OVP, OTP, OPP.
