Power Supplies

A DC laboratory power supply is an essential instrument in measurement technology and serves as a precise, adjustable power source for a variety of test and measurement tasks. This device supplies stable, regulated DC voltages - and often currents too. This allows electronic circuits, components and systems to be operated and characterised under controlled conditions.
Areas of application
- Development and characterisation: of circuits: Voltage and power supplies are characterised by their precision. When developing circuits, it is crucial that the components are operated under definable conditions. The supply voltage range can be set precisely using a DC laboratory power supply unit. This makes it possible to analyse the influence of different voltage levels on the circuit behaviour. The characteristic curves are examined as part of the analysis. By using variable voltage and current limit values, it is possible to precisely determine the operational characteristics of individual components, such as semiconductors or transistors. Engineers can use this to characterise the response range, linearity or threshold value of a component, for example.
Troubleshooting and system diagnosis:
- Targeted load tests: A DC laboratory power supply unit makes it possible to specifically simulate different load conditions. Developers and service technicians can test short-circuit or overload situations, for example, in order to identify faulty components or diagnose circuit problems.
- Stability test: The stable, adjustable current and voltage supply means that long-term load tests can also be carried out. This helps to assess the reliability and resilience of circuits and detect potential weak points.
- Calibration and measurements in quality assurance: Reference voltage source: Many measuring instruments and sensors require a stable voltage reference for calibration. DC laboratory power supplies offer a safe and constant power supply for this purpose, which serves as the basis for accurate measurements and minimises measurement uncertainties.
- Integration into automated test systems: Modern DC laboratory power supplies are often equipped with programmable voltage and current curves as well as remote control functions. This allows them to be used in automated test benches in which repeatable and documented test cycles are carried out during series production.
Simulation of real operating conditions:
- Varying operating conditions: In practice, electronic systems often have to be operated under fluctuating or special supply conditions. A DC laboratory power supply can be used to simulate such scenarios - for example voltage dips or variable loads - in order to test the behaviour of circuits under real conditions.
- Dynamic load simulation: Some models allow the generation of dynamic voltage jumps or current profiles. This is particularly useful for investigating the response behaviour of control circuits, power supply units or other component groups under transient conditions.
Education and research:
- Practical demonstrations: In educational institutions, a DC laboratory power supply illustrates basic principles of electronics, as students can directly observe the influence of voltage and current changes. This promotes a deeper understanding of circuit design and measurement technology.
- Experimental research: In laboratory environments where new technologies and components are being developed, the DC laboratory power supply provides a flexible and precise energy source for carrying out complex series of experiments and validating innovative approaches.
