Emulate the Power Grid

The Regenerative Grid Simulator – RGS Series is compact with high-power density, providing 12kVA/kW up to 21kVA/kW in a 4U chassis. Test systems can be paralleled up to 168kVA/kW in a single 19” cabinet. Dual cabinets can parallel up to 252kVA/kW.

The Regenerative Grid Simulator RGS Series simulates almost any power grid disturbance and distorted waveforms. The load option offers a complete solution if needed.

Test applications: Utility grid, microgrid, EV chargers, Vehicle-to-Grid (V2G), Vehicle-to-Home (V2H), Solar PV/grid-tied inverters, home energy storage systems, UPS, PDUs, and more. 

2-in-1 Regenerative Grid Simulator

Seamless Grid Simulation with Constant Power Voltage Range

Accurately simulate the power grid with seamless transition of voltage ranges. A single constant power voltage range for both higher current at lower voltage and higher voltages at lower currents eliminating the need to switch between voltage ranges. This prevents potential disruptions in output power.

Regenerative Grid Simulator Voltage Range

Exceptionally High Current

The RGS Series provides a broader range of current eliminating the risk of over or under sizing the power source. This reduces the need for additional capital investment. The diagram to the right illustrates the RGS’s capability to provide 20% more current from 120V to 200V when compared to a typical grid simulator that maxes out at 35A/phase.

RGS Regenerative Grid Simulator - More Current vs. Competitor

Flexible Output Configuration for Accurate Grid Simulation

Simultaneous AC and DC operation of modes per phase(or channel), and the automatic switching of output modes provides test engineers with a unique capability and the highest degree of flexibility. AC, DC, (AC+DC optional) output configurations are available in single, split, three phase and multi-channels with optional isolated neutrals in AC and DC.

Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.

NOTES

  • All RGS models have a single voltage range with constant power profile. This eliminates the need for switching between a high and a low voltage range. If desired, a low voltage range can be simulated.
  • Maximum current ratings shown are available up to maximum power point. Voltage and Current follow constant power profile so higher current at lower voltage and lower current at higher voltage is available.
  • Three phase input: 380 ~ 480 VAC ± 10% input range. All models have active power factor corrected AC inputs. Models above 12kW require 380~480Vac Input service to deliver full power. 208-240Vac models are not available at this time.
  • 19 Inch Cabinet not included with parallel system kits. Contact us for integrated cabinet systems.
  • Lower power RGS models can be upgraded to higher power levels using our POWER FLEX upgrade program. Contact customer service for details.

RGS Series Operating Features

Voltage Source Mode:

  • AC mode: The RGS simulates any AC power grid in the world through its wide voltage and frequency operating range. Both sourcing and sinking of full power is supported.
  • DC mode: The RGS provides a higher power, single, dual or triple DC rail power supply with bidirectional DC current flow and bipolar voltage ranges.

AC/DC Electronic Load Mode Option:

With this option, the RGS turns into a programmable AC or DC electronic load with 4-Quadrant capability so both true and apparent power can be drawn with programmable control over power factor, current crest factor, current waveshape etc. Instead of dissipating the energy received from the unit under test, the RGS load returns up to 90% of the absorbed energy back to the grid.

Time and Cycle Based Transients:

Create and execute transients that occur over a specified time segment or number of cycles to modify the output waveform, voltage, and frequency for any or all phases. An output trigger is provided for synchronizing external test equipment to the actual transient event.

Easy to Use, Multiple Control Options

Continuous Self Calibration:

Provides exceptional accuracy of the AC or DC output Voltage. When enabled, accuracy improves to ±0.02% referenced to the power source internal voltmeter.

Extensive Waveform Library:

Up to 200 different waveforms can be stored in the waveform library for execution as part of a steady state program or for substitution in any output phase as part of a transient test program. Memory location #1 is a non-editable high resolution sine wave. Locations 2 and higher are editable and can be substituted in any output phase. Store unlimited number of waveforms on the computer using the SmartSource Suite web browser interface.

Phase Conversion:

With the ability to provide single, split and three-phase outputs, the RGS Series is the perfect choice to provide 1 Phase to 2 or 3 Phase or 3 Phase to 1 Phase conversion.

Safety Features & Protection Limits:

Full galvanic isolation protects the user and UUT. Enhanced protection modes are includes programmable  limit protection modes for real power, apparent power, over voltage and over temperature.

Cooling & Energy Savings Mode:

Front forced air intake with rear exhaust. Automatic Fan Speed Control for low acoustic noise and extended fan life.  The Energy Saving Sleep Mode result in low power consumption during idle periods and extends the product life.
