  • How does the Power Commander regulate voltage?

  • The Power Commander uses the natural properties of magnetics to regulate voltage. The Power Commander changes the magnetic properties of a transformer through a control loop, thus changing the voltage either up or down.

  • What differentiates the Power Commander from other regulators?

  • The Power Commander can regulate voltage to within 1%, even with input voltage fluctuations of +10% to -20% of nominal, and from no load to full load. Most voltage regulators available today simply are not this precise. In addition, the output voltage may be sensed and regulated at the load, automatically compensating for line and wire losses due to long distance cable runs to the load!
