Tips: Characteristics of 4 kVA 3 phase isolation transformer at the AC power output

  1. Avoid the current distortion of non-linear load to affect the normal operation of AC power and influence to the Grid, it plays a role in purifying the power Grid.
  2. Take sample at the input end of this three phase 400/230V to 208/120V isolation transformer, so that the distortion of the non-linear load current will not affect the accuracy of the sampling and the control signal that can reflect the actual situation can be obtained.
  3. If the load is not balanced, it will not affect the normal operation of the stabilized voltage power supply.
