View PCR-WEA / WEA2AC Power Selection
AC power-source selection depends on more than nominal voltage. Define phase configuration, source capacity, frequency, waveform or disturbance needs, crest/inrush behavior, and automation requirements.
AC Power Test Architectures
Programmable AC sources can reproduce controlled voltage and frequency conditions, power-line disturbances, and higher-capacity multi-phase environments. Select the architecture from the DUT input and the conditions you need to simulate.
Use a programmable AC source when the primary requirement is repeatable control of the DUT input voltage, frequency, and test sequence.
Programmed voltage and frequency variation helps define the DUT operating window and behavior outside nominal mains conditions.
Disturbance simulation makes line events repeatable so the DUT response can be compared across development and validation cycles.
Higher-power AC systems require phase configuration, kVA, current, facility input, and cooling to be considered together.
Regenerative AC capability is configuration-specific. Confirm that the exact source model and facility interface support the required return-power behavior.
AC Source Selection
The same AC source family may cover several workflows, but phase configuration, capacity, frequency range, disturbance functions, and regenerative options vary by model and configuration.
| AC test requirement | Key selection factor | Typical use |
|---|---|---|
| General programmable AC | Voltage, frequency, capacity | Bench and automated AC-input testing |
| Voltage / frequency variation | Programmable range and transition behavior | Input-tolerance and operating-range evaluation |
| Power-line disturbance simulation | Event/sequencing capability | Dips, increases, interruptions, and mains-condition testing |
| Multi-phase / high-power AC | Phase configuration and kVA | Larger industrial and power-electronics DUTs |
| Regenerative AC | Supported regenerative configuration and facility interface | Energy-returning AC test systems where applicable |
Frequently Asked Questions
A programmable AC source provides controlled and repeatable voltage and frequency conditions. Depending on the model, it can also reproduce line disturbances or programmed sequences that utility power alone cannot provide repeatably.
Define the DUT input voltage, frequency, phase configuration, apparent-power requirement, current and inrush behavior, power factor, disturbance profile, duty cycle, and required automation interfaces.
It is the controlled reproduction of events such as voltage dips, increases, interruptions, or programmed line variations so the DUT response can be evaluated under repeatable conditions.
Use a multi-phase or higher-capacity source when the DUT input configuration or power demand cannot be served by a single-phase lower-capacity source. Confirm phase-to-phase/phase-to-neutral voltage, kVA, current, and facility input requirements.
Regenerative operation is relevant when the test system needs to absorb returned energy and the selected AC source configuration supports that behavior. Regenerative capability is configuration-specific and should be confirmed for the exact model.
