AC Load 4-Quadrant Operation

The most unique feature of the 9430 AC Load is the ability to operate in all 4-quadrants. This bi-directional capability significantly expands AC load simulation relative to 2-quadrant AC loads. More specifically, the 9430 AC load allows creating the reverse current caused by inductive or capacitive loads (low power factors); namely sending power back to the UUT (source) during part of the AC cycle. In this manner, the 9430 accurately duplicates real-world reactive electrical power flows.

 

HIVAR Design Provides Reactive Loading Without Derating True Power

This advanced design feature allows for testing high reactive load input power without the customary reduction of true power (Watts) normally required with conventional loads.

 

Several Emulation Modes

To provide testing under the broadest range of loading conditions, the 9430 AC Load will operate in several emulation modes including Constant Current (CC), Constant Resistance (CR), Constant Power (CP) and Constant Apparent Power (CS).

 

User-defined Waveforms

In addition to programmable power and crest factors, the 9430 AC Load is capable of creating non-linear waveforms using a unique graphics editor. This editor allows starting with a straight line or modifying a generated waveform based on current, power and crest factor.

 

Testing Applications

  • Full Line Disturbances at Any Power Factor

  • Grid Utility Test, Inverter Test, UPS Test

  • EV Load Testing

  • Switch, Fuse Test

  • Linear & Non-linear Loading, Inductive & Capacitive Loading Requirements.

Product Applications

The 9430 is a 4-quadrant, regenerative AC load that is current-regulated with selectable phase inputs/outputs and a built-in waveform digitizing measurement system. In the sink mode, it sends power back to the facility mains rather than dissipated as heat. The 9430 can simulate almost any linear or non-linear load. Applications include testing of Vehicle to Grid (V2G), solar and grid-tied inverters, UPSs, AC sources, rectifiers, circuit breakers and fuses.
