Frequently Asked Questions
-
What is an AC power source?An alternating current, or AC power source, provides controlled power to different types of loads.
An AC power source has many uses in many applications where the power needs to be either tightly controlled or even dynamically changed to replicate real-world behaivors and events. These applications can range from specific Engineering testing on devices to standards compliance testing such as IEEE1547 and UL1741. They can be used to simulate real-world electrical conditions like surges, outages, or voltage fluctuations to ensure devices can handle them. -
What is a single-phase AC power source?
A single-phase AC power source uses two wires: a phase wire and a neutral wire. Power flows from the phase wire through the device and returns via the neutral wire. Single-phase systems are simpler, need fewer conductors, and are typically used for lighting, heating, and small appliances. As an example, the typical AC power that you have in a home is single phase.
-
What is a three-phase AC power source?A three-phase AC power source uses three wires to carry current, often arranged in either a wye or delta configuration. In a wye system, a neutral wire is also used. Three-phase systems are more efficient for delivering large amounts of power and are typically used in industrial equipment and heavy machinery.
-
What is the difference between AC and DC power sources?
- AC (Alternating Current) power is ideal for sending electricity over long distances and is distributed through the electrical grid.
- DC (Direct Current) power flows in one direction and offers very stable voltage, which is why it’s commonly used in batteries and most electronic devices.
Many devices either run directly on DC power or convert AC to DC using a rectifier inside the device.
-
What is a programmable AC power source?
A programmable AC power source lets you adjust the output voltage, frequency, and waveform to simulate different power conditions.
Unlike fixed-output sources, a programmable source can recreate real-world situations like power surges, outages, or voltage changes — making it ideal for product testing, R&D, and production environments. -
How can I control an AC power source remotely?
Programmable AC power sources can be controlled remotely using communication interfaces like GPIB, LAN, USB, or RS-232.
They also support SCPI (Standard Commands for Programmable Instruments) commands and can integrate easily into automated test setups using various software drivers. -
How do I choose the right AC power source for my application?
Choosing the right AC power source depends on your specific needs:
- Required voltage, current, and total power
- Frequency range
- Type of waveform you need (pure sinewave, distorted, etc.)
- Special functions like harmonic generation or advanced measurements
Understanding your application’s power demands and test requirements is key to selecting the right model.
