    3 kVA Isolation Transformer Dimension
    3kva isolation transformer dimensionTips: No-load Current of the Transformer
    No-load current refers to the current running in the line terminal when a rated voltage with a rated frequency is applied to the terminal of a winding while other windings are open circuit. It's generally expressed by the percentage of the winding's rated current. So the reactive component of the no-load current is greater than the active component and a no-load current is essentially a reactive power, which is generally called as magnetic current. When the transformer is running in no load, the output power is zero, however, a small part of active power will be absorbed from the power supply to compensate the power loss of the transformer, and this part of power becomes heat and dissipates, namely the commonly said no-load loss.

    Existing reviews of 3 kVA Isolation Transformer, single phase, 208V to 120V
    Transform 110V to 220V or 220V to 110V
    The isolation transformer arrived on time and exceeded my expectations for quality. It works perfect in the US with my European devices, transform 110V to 220V or 220V to 110V.
