The Difference Between Single vs. Three-Phase AC Voltage Most of us are familiar with the single phase voltage in our homes provided by the local utility. For the US, this is typically 120V. For single phase voltage, the voltage is expressed as a Line to Neutral voltage between two power conductors (plus a safety ground). […]

What is Inrush Current? While inrush current has a peak current value, the term “Inrush Current” is commonly used to describe the current that is required to energize an AC powered device or product when first applying voltage and power to it. This is especially true for inductive loads such as transformers, Inductors and electric […]

What Is Programmable Impedance (Prog. Z)? Hate to disappoint, but programmable Z on an AC power source has nothing to do with getting sufficient sleep. Instead, the Z refers to the output impedance of the power source. A low AC source output impedance means there is little or no voltage drop at the output of […]
