Drive bus voltage of
inverter compressor
V
● The normal bus voltage is 1.414 times of
the power supply voltage. For example, if
the three-phase power supply voltage is
390V, then the rectified bus voltage is:
390V×1.414 = 551V. The normal deviation
between the measured value and the
calculated value within 15V.
