Accurately Emulate Grid Conditions and Verify Compliance
The increasing development of grid-connected devices like Solar Inverter, EV charger with V2G capabilities require accurate compliance testing to meet regulatory standards such as IEEE 1547 and UL 1741. The Grid emulation demands for simulating LVRT, HVRT, Voltage dip immunity, voltage sags, Harmonics, Interharmonics, flicker events, anti-islanding conditions, and other real-world grid phenomena to support advanced testing requirements. RGS series along with Pre-written Test standard sequence options allows user to perform these test accurately as per standard.
Simulate Harmonics AND Interharmonics
The RGS Regenerative Grid Simulator built-in digitizer and scope with 200 µs resolution. Supports LIST, PULSE, STEP, and generates Sine, Square, Triangle, Clipped, Harmonics, and Inter-harmonics.
- AC, DC configurations
- Simultaneously test AC and DC, Source or Load on separate phases
- Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.
Test AC or DC, as a Source or Load - Independently or Simultaneously
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 option) configurations in single, split, three phase and multi-channels
- Simultaneously test AC and DC, Source or Load on separate phases
- Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.

Notes
- For higher power levels up to 1.296MVA, contact Factory for more details.
- 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 12kVA 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.
