Chroma 61809 Regenerative Grid Simulator

The Chroma 61809 is a model in the Chroma 61800 3U high series of regenerative grid simulators include three models with power ratings of 9kVA, 12kVA, and 15kVA and include single phase and 3-phase operation.

With output voltage ranges up to 350VLN and 606VLL, each model can achieve 700VLN by a single phase 3-wire setup. Users are able to increase output power by configuring up to three units in parallel. 

Chroma 61809/61812/61815 models are regenerative providing a complete energysaving solution. The power generated by the DUT during the test can be efficiently fed back to the grid, rather than dissipated as heat, which protects the environment and lowers the cost of operation. With this capability, these models can be applied to applications in green energy products, such as PV inverters, energy storage systems (ESS), power conditioning systems (PCS), micro grids, power hardware-in-the-loop (PHIL), electric vehicle power supply equipment (E V S E), on-board charger (O B C) and bidirectional on-board charger (BOBC), etc. 

By using full digital control technology, these models provide a maximum 350VLN output voltage and 30Hz to 100Hz output frequency. The total harmonic distortion rate is less than 0.5% at full load and 50Hz/60Hz output frequency. In addition to AC output, a DC output mode and AC plus DC output mode is included which can be expanded to DC test and AC test with DC bias voltage. The current output capability can provide 3 times the RMS peak current, which is suitable for a DUT input inrush current test. 

This model is also able to provide precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor and many others. By applying advanced DSP technology, they can easily simulate power line disturbance (PLD) using LIST, PULSE and STEP modes. Additional features such as the waveform synthesis function allows users to program various distorted harmonic waveforms required by some regulatory standards. 

With the intuitive 5" LCD touch screen interface, users can quickly get familiar with the instrument's operation. Remote interfaces include standard USB and optional GPIB, CAN, or LAN interfaces. Instruments can be controlled by computer and Chroma Softpanel software for fast digital operation. In addition, Chroma also provides control drivers where users can use LabVIEW software to program integration applications of the control system
