Regenerative Grid Simulator
Chroma 61800
A full 4-quadrant, fully regenerative AC power supply designed for common electrical product testing, such as home appliances and industrial electronics, that require a programmable input source.
Power Rating
45kVA~105kVA
Voltage Range
0~300V/0~520V
Frequency
30Hz~100Hz
The 61800 Grid Simulator is a full 4 quadrant, fully regenerative, AC power supply designed to simulate worldwide power line conditions and disturbances for testing PV Inverters and on-line UPSs as well as Vehicle to Grid (V2G) and Energy Storage Systems (ESS).
- Standard output voltage of 330V L-N as compared to 300V L-N found in the market – sufficient to cover a +10% variation for 480V L-L applications
- Optional 0-400V L-N / 0-692V L-L opt. that does not require a transformer
- Maximum power delivered down to 200VAC L-N which provides a wider output power range
- Simulates distorted voltage waveforms and transient conditions
In addition to supplying clean, precise and stable AC voltage for regular applications, the 61800 is capable of simulating various types of distorted voltage waveforms and transient conditions required by product validation testing. These are accomplished using built-in programmable waveform functions such as LIST, STEP and PULSE modes. The STEP and PULSE functions allow users to perform single or continuous step changes of output voltage. LIST mode is a more versatile function, and allows users to compose complex waveforms of up to 100 sequences. Voltage waveforms required by immunity specifications such as IEC 61000-4-11 (short interruption and voltage dropout) can easily be achieved by the 61800 Regenerative Grid Simulator.
Smart Grid and EV Related Test Applications
The 61800 Regenerative Grid Simulator is also ideal for smart grid and EV related test applications such as Vehicle to Grid (V2G) and Energy Storage System (ESS) testing. The 61800 regenerative grid simulator’s extensive feature set is not limited solely to product development during R&D, they are also valuable during design and quality verification as well as throughout various production stages. Using state-of-the-art digital control technology the 61800 can deliver up to 330VAC at output frequencies ranging from 30Hz to 100Hz. The AC+DC feature allows for applications that require a DC offset bias.
