Datasheet

The Chroma 61830 Regenerative Grid Simulator features 4-quadrants with an advanced design for compliance, safety, and product verification testing. The units in the 61830 series have a maximum AC output power of 30 kVA to 60 kVA. With a 0 to 300VLN / 0 to 520VLL voltage range and a 0.2% + 0.2% F.S. accuracy, the 61800 series can provide precision measurements, such as RMS voltage, RMS current, true power, power factor, and current crest factor.

The Chroma 61830 Regenerative Grid Simulator allows users to change and set parameters to create real-life grid environments and conditions. The unit is designed to simulate grid characteristics for testing PV inverters and on-line UPSs while being capable of simulating various types of distorted voltage waveforms and transient conditions. The Chroma 61830's regenerative feature provides an effective energy-saving method as the generated energy is fed back to the grid instead of dissipated as heat during operation. The unit highlights a 30 Hz to 100 Hz frequency range with a 0.01% accuracy, ensuring testing reliability.

Supported variations include units with different frequency ranges, phase angles, voltage amplitudes, and voltage drops in either single or three-phase modes. Unbalanced three-phase conditions can easily be simulated.
