*1 Measurement method complies with Japan Testing Machinery Association (JTM). However, the calculation method is half the maximum value minus the minimum value when stable.

  • This is the measured performance at the control point after stable operation for 30 minutes with an ambient temperature of +5 to +32°C and no load.
  • The allowable voltage fluctuation is within ±5% of the rated voltage, and the allowable frequency fluctuation is within ±1% of the rated frequency.
  • TVOC concentration of installation space (supply air) must be less than 300 μg/m³, and there must not be a significant fluctuation.
