Itech IT8000 Series Regenerative DC loads

The Itech IT8000 Series Regenerative DC loads are powerful electronic loads in a compact format. The many integrated features allow the user to simulate different load profiles where the energy absorbed is returned to the grid. This environmentally friendly technique has an efficiency of up to 95% and significantly reduces the waste of energy, which is often lost as heat. With its modular design and high power density, the Itech IT8000 offers a load capacity of up to 18kW in 3U-high housing. Higher power ratings up to 1,152kW are made possible through master-slave parallel switching with active load current sharing.

Features

The Itech IT8000 series is suitable for DC voltages up to 2.250V and currents up to 2.040A. A stand alone master – slave combination is suitable for a power up to 144kW. Parallel connection of several of these stand alone units makes an output of up to 1.125kW possible.

The standard built-in arbitrary waveform generator offers the user enormous flexibility in programming load profiles. The different profiles and steps are easily imported or exported via USB with the LIST function.

For use in current energy storage applications, this regenerative DC load is already equipped with a number of powerful functions as standard, including the;

• Power accumulation function
• Battery test function
• Auto-test function
• Short circuit test function
• Pre-charging function

In addition, the IT8000 Series Regenerative DC Electronic load is provided with protections for: OVP/OCP/OPP/OTP/UVP, Vsense anti-reverse connection and voltage transient drop

For applications in an automatic test setup or ATE environment, communication is possible via USB/CAN/LAN/digital IO interface and optionally via GPIB/Analog&RS232. The programming functions support the SCPI protocol and LabVIEW drivers are available.

Applications

These regenerative loads are suitable for a wide range of high power DC load tests in industry, defence, aerospace and energy storage systems. For example: testing of charging stations, discharging and loading of (car) batteries, fuel cells and batteries. But also server (DC) power supplies, telecommunication power supplies, generators, capacitors (banks), rectifiers and UPSs.
