Product catalog summary

Document Overview: This technical document from Mitsubishi Electric Corporation presents actual measurements of waveform behavior at AC load break points, focusing on AC output voltage and current characteristics.

1. Specifications and Measurement Context

The document details the waveform characteristics observed during the transition from maximum load to no load conditions at the AC output. It emphasizes that the AC output voltage and frequency remain stable and free from distortion throughout the load break event.

2. Key Parameters and Observations

  • AC Output Voltage and Current: Measurements show the voltage (V) and current (A) waveforms at the load break point.
  • Load Break Point Behavior: Transition from maximum load to no load is monitored, highlighting the system's ability to maintain voltage and frequency without distortion.
  • System Components: The system includes APS1 and APS2 units connected via AC bus lines, with input and output voltages monitored.

3. Operational Procedures

The document references operational states such as APS1 stop and APS1 restart, indicating control sequences affecting output current and voltage during load changes.

4. Important Notes

  • Specifications are subject to change without notice.
  • Measurements are effective as of June 2022.
  • All data pertains to the Mitsubishi Electric HQ 2206 model.

5. Summary of Technical Significance

The key takeaway is the confirmation that the AC output voltage and frequency maintain integrity without distortion during load transitions, which is critical for reliable power supply and system stability in industrial applications.
