This model has been replaced by the IT8000 series. The Itech IT8300 series regenerative DC Loads are green electronic loads: instead of converting the energy into superfluous heat, it is fed back into the grid. The advantages are:

  • Better for the environment and a lower energy bill
  • No air conditioning needed to dissipate this excess heat
  • The lighter mains connection is often a financial advantage for larger capacities.
  • The units are quiet, compact and reliable due to the greatly reduced heat generation.



With the Itech IT8300 Series regenerative DC Load there is a choice of two voltage ranges: 80 V and 800 V. This allows suitable loads to be found for both low and high voltage applications such as those found in electro-automotive test rigs. Maximum load capacities are between 3.5 kW and 73.5 kW per unit and can be 105 kW or more by master-slave parallel operation. The maximum standalone input current is up to 3570 A.

The loads operate in CC, CV, CR and CP mode, Dynamic mode and List mode. There are functions for battery testing, automatic testing and short-circuit testing. Control is via the front panel or via a host computer. All important parameters are available on the built-in display: Vdc, Idc, Pdc, Vac, Pac, Fac and Wac. The host can be connected via RS232, RS485, CAN, USB, GPIB and LAN. An analogue interface is also available. The IT8300 is programmable via SCPI. For the IT8300 series various software tools are also available, as well as the Labview drivers.

The IT8300 has extensive OVP, OCP, OPP and OTP safeguards, grid status detection and anti-islanding protection. Feedback efficiency is up to 95%. The energy delivered back is tracked by means of a built-in kilowatt hour meter.
