Frequently asked questions
Single-phase alternating-current (AC) power supplies generate just one AC voltage between their two output terminals. Their output power is good enough for most home appliances and small devices.
In power supplies that are connected to the main power grid, one of the terminals is called live or hot and always carries the current to the load. The other terminal, called neutral, just acts as the return path for the current and is ideally at zero volts relative to the mains ground.
However, in some power supplies that are designed to be isolated, there may not be a designated neutral with a direct electrical path to the main ground. Instead, they may have two live wires of opposite phases in a 120/240V split-phase arrangement.
These are some key aspects to look at when selecting AC power supplies:
• Output frequency: This is the range or set of frequencies supported at the output.
• Output power: This is the maximum power the AC power supply can deliver.
• Output current: This is the maximum RMS current from the AC power supply.
• Output voltage (VAC): This is the RMS voltage range available from the AC power supply.
Additional factors to consider include:
• Efficiency: This indicates how effectively the AC power supply converts input energy to output energy.
• Power factor: This represents the phase alignment of the AC voltage and current.
• Total harmonic distortion: This is a measure of the distortion in the AC waveform from the ideal sine wave.
• Load regulation: This indicates the stability of the output voltage or current when the load on the supply changes.
• Line regulation: This indicates the stability of the output voltage or current when the input voltage fluctuates.
• Calibration certificates: They indicate that the power supply has been tested according to international calibration standards.
You can operate an AC power supply remotely through standard communication interfaces, including GPIB, LAN, USB, and RS-232. Remote control enables seamless integration into automated test systems. Additionally, some AC power sources support SCPI (Standard Commands for Programmable Instruments) commands, facilitating automation and customization.
