Frequently Asked Questions

How do I select the right AC power supply for my application?

Consider the required phase configuration, power rating, voltage and frequency range, harmonic analysis, power-line disturbance simulation, and applicable compliance standards. Single-phase supplies suit general development and automated testing, while three-phase models support higher-power industrial, avionics, inverter, and motor-drive applications.

What should be considered when choosing a DC power supply?

Key considerations include voltage, current, power, output channels, ripple and noise, transient response, measurement accuracy, and automation requirements. Autoranging, remote sensing, sequencing, and regenerative operation may also be required for more advanced applications.

Can power test instruments be integrated into automated test systems?

Yes. AC and DC power supplies, electronic loads, and source measure units offer connectivity such as LAN, USB, GPIB, LXI, SCPI, and digital I/O. These interfaces support remote control, test sequencing, synchronisation, data logging, and high-throughput automated testing.

What is a DC electronic load used for?

A DC electronic load absorbs controlled amounts of power to evaluate batteries, power supplies, converters, fuel cells, and other DC sources. Constant current, voltage, resistance, and power modes allow engineers to simulate different load conditions and assess device performance.

What is the difference between a source measure unit and a DC power supply?

A DC power supply primarily delivers controlled power to a device. A source measure unit sources and sinks voltage or current while simultaneously measuring the device response with high accuracy, making it better suited to detailed current-voltage characterisation and low-level measurements.

Which power test instruments are suitable for battery, EV, and renewable-energy testing?

Battery emulators, regenerative DC power systems, electronic loads, photovoltaic array simulators, and high-performance source measure units support battery profiling, charge and discharge testing, inverter validation, energy recovery, and dynamic power simulation.
