Best Regenerative Grid Simulators for Green Energy Applications

Regenerative grid simulators provide a complete energy-saving solution. Power generated by the DUT is fed back to the grid which protects the environment and lowers the cost of operation. Built for applications in green energy, such as PV inverters, energy storage systems (ESS), vehicle to grid (V2G), power conditioning systems (PCS), microgrids, power hardware-in-the-loop (PHIL), electric vehicle power supply equipment (EVSE), on-board charger (OBC) and bidirectional on-board charger (BOBC), etc.

  • Power ratings of 9kVA, 12kVA, and 15kVA in selectable single- and 3-phase
  • Output voltages up to 350VLN and 606VLL, achieves 700VLN by a single-phase 3-wire setup
  • 30Hz to 100Hz output frequency – total harmonic distortion rate is <0.5% at full load
  • Configure up to three units in parallel
  • Regenerative AC Load option
  • Standard USB, LAN / Optional GPIB and CAN interfaces
  • 5” touchscreen
  • Available softpanels control and LabView drivers

In addition to AC output, a DC output mode and AC plus DC output mode is included, which can be expanded to a 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.

Precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor, and many others. Simulate power line disturbance (PLD) using LIST, PULSE, and STEP modes. The waveform synthesis function, allows users to program various distorted harmonic waveforms required by some regulatory standards.

Apply regulatory testing to:

  • IEC 61000-3-2/-3- 3/-3-11/-3-12 (international regulations for AC voltage testing)
  • IEEE 1547/IEC 62116 (international regulations related to green power generation)

AC Load Function

Our regenerative AC Load Function allows a single unit to function as either an AC Load or an AC Source. This function is intended but not limited to EVSE charging station, hybrid PV inverter, UPS, and bidirectional on-board charger test applications. The four-quadrant regenerative function provides both energy and cost savings, is single-and three-phase selectable, and supports up to 3 units in parallel.

High Power Density

An advanced digital control system and cooling technology allows for a form factor at 3U height as well as achieving outstanding hardware capabilities like 15kVA output power, 350VLN wide output voltage range, 1-phase / 3-phase output mode, 100% DC output, and regenerative function. Chroma has also improved transient capabilities, like rising / falling slew rate of output voltage, providing even a better power test solution for users.

Intuitive Touch Screen

Chroma 61809/61812/61815 models are equipped with a 5″ LCD touch screen interface providing users with an intuitive UI interface to quickly perform multiple settings and operations. The rotary knob can enlarge the display for the setting parameters of operation for fine-tuning of parameters. The display mode can expand the measurement value to full screen, making it easy to observe.
