Validating inverters, UPS systems, and EV power conversion equipment requires a source that can reproduce abnormal grid conditions and absorb power flowing back from the unit under test. Intepro now offers the Ainuo ANRGS(F) Series Regenerative Grid Simulator, a programmable AC/DC source that simulates real-world grid conditions while sourcing and sinking power across all four quadrants. Its regenerative operation reduces energy use and operating costs during high-power testing.

EMC Test Functions

• Harmonics and interharmonics emissions: Harmonic synthesis from the 2nd to 50th order with a 3,000 Hz bandwidth simulates grid distortion to test equipment tolerance. Standards: IEC 61000-3-2, IEC 61000-3-12
• Voltage dips, short interruptions, and variations: Step, pulse, and sequence programming generate voltage sags, rises, dropouts, and transients. Standards: IEC 61000-4-11 (AC), IEC 61000-4-34 (high current)
• Voltage fluctuations and flicker: Evaluates how equipment-induced fluctuations affect power networks and how susceptible the device is to rapid line variations. Standards: IEC 61000-3-3, IEC 61000-3-11
