Itech, supplier of AC/DC Power test solutions has introduced an “all-in-one test solution” with the IT7900P series, a combination of an AC/DC Grid emulator & regenerative AC/DC load. The IT7900 series grid emulator was already innovative when we look at the many functions and the user-friendly operation. With the -P version, the unit can now also be used as a 4-quadrant load in both AC and DC mode, whereby the unit is also regenerative.
In AC mode the IT7900P supports various operating modes including; CC/CP/CR/CS/CC+CR/CE and that over a frequency range of 16-500Hz. In CE mode it is possible to simulate various circuits including single phase rectification, RLC and shunt RLC. The Crest factor is adjustable between 1.414 ~ 5.0. This Grid Simulator is also equipped with an anti-islanding test mode where RLC (resistive-inductive-capacitive), parameters are the definition for testing Anti Island detection circuits.
The Itech IT7900P models are available from 6kVA to 960kVA. The 3 phase output has a voltage range of 0-350V LN and a frequency range of 16Hz – 2,400Hz in AC source mode. As a DC power supply the voltage range is -495～495Vdc (1phase/multichannel) and -990～990Vdc in reverse mode. The IT7900P is equipped with an intuitive touch screen which guarantees smooth operation and is equipped with a built-in power meter, a harmonics waveform synthesizer and a scope function.
The STEP, LIST and PULSE mode makes the ITECH IT7900 series suitable for simulating changing AC and DC grids. This includes, for example, short-term PQ events. The analysis and simulation up to the 50th harmonic and the programmable output impedance makes the Itech IT7900 suitable for many applications, including IEC testing. Remote control is possible via the standard USB/CAN/LAN and digital I/O interfaces.
