Key Features and Functions

The 9410 from NH Research is a four-quadrant (bi-directional) AC/DC source with selectable phase outputs, a built-in waveform-digitizing measurement system and robust line disturbance creation tools. When used in the regenerative (sink) mode, it sends returned power back to the facility mains rather than being dissipated as heat. The most frequent application of the 9410 is use as a grid simulator for testing PV inverters and other grid-tied products for compliance to industry standards.

Features

  • 8 models – 4kW/10.5kVA to 96kW/252kVA
  • Output AC Voltage Ranges – 175, 350VRMS L-N
  • Output DC Voltage – 200, 400VDC
  • Output Frequency – DC, 30 to 100Hz
  • Programmable 1, 2 or 3-Phase modes
  • Full 4 quadrant AC source operation
  • High resolution waveform capture on all V & I
  • Sink power regenerated back to facility
  • 9” Touch-Panel user interface
  • SCPI programming & NI LabVIEW drivers

Advantages

  • Bi-directional AC – Inverter testing & μgrid simulation
  • More reactive power per kW
  • Simplifies automated test stand development
    – Software selectable 1, 2, or 3 Phase operation
    – Isolated digital inputs & outputs
    – Built-in SW watchdog & safety limits
  • Software tools to shorten test development time
    – PC-based tools & NI certified drivers
    – NI certified LabVIEW & IVI-C/IVI-COM drivers
    – Optional: Enerchron® test sequencer

Benefits

  • Regenerative, returns greater than 85% of power to the facility, which provides significant electrical savings.
  • Field upgradeable to higher power
  • Fully emulate any utility/grid condition
  • Simulate non-ideal Phase phase angles (A-B & A-C)
