For large equipment with three-phase input! For aircraft ground power! Automation voltage/frequency converter (VVVF)! Maximum output of 90kVA possible!
The "QA Series" has been updated while broadly covering the specifications and performance of the equivalent conventional products, the "6300/6500 Series." The QA-T4 Series is a three-phase power supply capable of outputting from 15kVA to 90kVA. It is ideal for testing refrigeration and air conditioning systems, large industrial electric motors, and charging stations that require high capacity. The QA-T4-4 Series (dedicated to three-phase output at 400Hz) is a three-phase power supply specialized for the aerospace industry, capable of outputting from 15kVA to 90kVA. With an output frequency of 400Hz, it is optimal as a power conversion type ground power supply to replace conventional engine generators. The QA-S2 Series (single-phase output) is a single-phase AC power supply capable of outputting from 10kVA to 30kVA. Its advanced switching technology enables a high power and compact lightweight design, achieving space-saving. Four LED displays allow for simultaneous measurement of frequency, voltage, current, power, or power factor. Each button is reserved for specific functions, making it easy for anyone to operate.
