Laboratory power supply Voltcraft VSP 2405, adjustable 0.1–40 V DC, 0–5 A output

The Voltcraft VSP 2405 laboratory power supply delivers adjustable DC output from 0.1 to 40 V with a maximum current of 5 A. Designed for bench-top use, it provides a stable, low-noise output suitable for electronics testing, prototyping, component characterization and repair tasks. The unit features precise voltage and current adjustment controls plus clear front-panel readouts to monitor settings and load conditions during experiments and assembly work.

Advantages

The compact design combines a wide voltage range and a 5 A current capability in a single, benchtop-friendly instrument. Accurate control of both voltage and current enables safe operation when powering delicate circuits or when performing load testing. The front-panel indicators and adjustment knobs are arranged for straightforward operation, and the supply is engineered to deliver stable, regulated DC output with low ripple for reliable measurement results.

Suitable for

• Electronics prototyping and circuit development
• Component testing and characterization
• Repair and maintenance of electronic devices
• Educational laboratories and training workshops
• Bench work requiring adjustable voltage and current

Key specifications

• Output voltage range: 0.1–40 V DC
• Maximum output current: 0–5 A
• Regulation: stabilized DC output with low ripple
• Front-panel voltage and current controls for fine adjustment
• Digital or analog readout on the front panel for voltage and current monitoring
• Benchtop form factor suitable for laboratory and workshop environments

How to use

Place the power supply on a stable, ventilated bench surface and connect the mains power according to the local supply requirements. Before connecting the load, set the voltage and current controls to the desired starting values and verify the front-panel readouts. Connect the device under test using appropriate leads and observe polarity markings. When powering sensitive circuits, use the current-limiting feature to prevent overcurrent; adjust the voltage slowly while monitoring the current display. After tests are complete, reduce the output to zero and disconnect the load before turning off the mains.

Recommendations

Use properly rated leads and connectors, ensure good ventilation around the unit, and avoid exposing the supply to moisture or excessive dust. For accurate measurements, allow the supply to warm up briefly before precision tasks. When testing unknown circuits, start with a low current limit and increase cautiously while monitoring load behavior.
