Itech IT6000B bi-directional DC power supply
The Itech IT6000B is a new series of programmable DC power supplies for higher powers with special features. These DC power supplies are bi-directional and can, therefore, supply as well as absorb current and power. Switching from source to sink is seamless. And with the push of a button, you can switch from bi-directional power supply to regenerative load. This bi-directional power supply (also called two quadrant power supply or unipolar power supply ) is ideal for testing as well as emulating batteries. Solar array simulation for testing PV inverters including MPPT tracking is also possible.
Features
The Itech IT6000B series are available in 6 different voltage ranges; 0-80V, 0-300V, 0-500V, 0-800V, 0-1500V and 0-2250V. The power range runs from 5 kW to 144 kW in more than 56 versions. The maximum current is up to 2040 A. Due to the power flex concept, the maximum power of the IT6000B can be used in a wide range of voltage / current levels.
The IT6000B family offers fast rise and fall times. This is, among other things, useful when emulating batteries. The two quadrant power supply design makes the unit ideal for continuous sink/source applications such as automotive electronics, solar panel I-V curve simulation, DC motors, batteries, and so on. If this bi-directional power supply works as a load, the power absorbed from the DUT is regenerated to be fed back into the mains.
The up/downtime of the IT6000B unipolar power supply is below 15..30ms depending on the load. The transient response time is less than 2ms. Changed setpoints or loads are quickly processed without overshoot. For higher powers, multiple units can be connected in parallel in Master-Slave mode. The excellent performance is maintained. The units are easily programmable and of course have List-mode for storing, calling, and executing program steps.
The IT6000B series power supplies are OVP, OCP, OPP, and OTP secured and come standard with a multitude of interfaces: USB, CAN, LAN, and digital IO interface.

There are three test options by simulating different power supply units: Battery input, AC input, PV input to converter.
The standalone charging mode of IT6000B can perform battery discharge.
With the optional SAS1000 solar module simulation software, users can easily use the software to run, measure, display the maximum power and PV inverter status in real-time display and record the value. With built-in EN50530, Sandia, NB/T32004, CGC/GF004, CGC/GF035 regulatory testing procedures, it is easy for users to simulate I-V curves, test the static and dynamic MPPT performance of PV inverters and generate reports. The simulation also offers shading and table mode, users can input up to 4096 point array to edit a shielded IV curve and achieve a dynamic shading effect. It is also possible to save 100 I-V curves under different irradiance and temperature storage, set the operating time and test the long-term MPPT of PV inverters under different climatic conditions.
Automotive electronics often face power transients during vehicle start-up and operation. To ensure that the device under test is can withstand these actual power transients, the tester must simulate worst-case power transient conditions during the test. According to the relevant industry standards, the IT6000B has built-in standard voltage curves for cars, to be named LV123, LV148, DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848. One can easily recall various waveforms directly, such as the waveform of voltage drop during vehicle start-up, pulse waveforms and other related automotive electronics waveforms for performance testing. Available voltage grades in 12V, 24V and 48V.
