Compare AC-input bench power supplies and DC-input programmable modules for electronics testing, repair and prototyping. Choose the input format first, then match the output range and control options to your load.
Choose the input format first
An AC-input bench supply connects to the mains voltage specified for the selected instrument. A DC-input buck module needs a separate compatible DC source. Do not connect a DC-input module directly to AC mains.
These are the listed adjustment ranges, not a promise that every maximum voltage and current can be used together. Check the intended operating point, input-source capacity, cooling and model limits.
Check the configuration and controls
Input option: For an AC-input model, match the selected voltage option and input label to your supply. For a DC-input module, confirm the external source and wiring required.
Output requirement: Compare the load's voltage, normal current and startup requirement with the instrument's supported operating conditions.
Communication and package: TTL, 485 and RF options differ by model and variant. Check the chosen interface, remote controller and included cables on the product page.
