Resistive vs. Regenerative AC Loads for Burn-In Testing Burn-in testing is a critical step in ensuring the reliability and durability of electronic products across industries like energy, automotive, telecommunications, and more. By subjecting components to prolonged operation under elevated stress conditions, burn-in testing helps identify early-life failures and validates product quality before deployment. Traditionally, resistive […]

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 Constant Power and How Does it Work? Programmable DC power supplies have historically been characterized by a point rating power output capability in Watts. Point rated implies that maximum available power output from the power supply is available only at one operating point. This power output point is where both DC voltage and […]

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 […]
