DC Regulated Power Supply 30V5A 150W with Overvoltage and Short Circuit Protection

This DC regulated power supply delivers stable, adjustable 30V 5A output for experimental, repair, and fast-charging applications. With ±0.1% voltage and current accuracy, it ensures reliable performance during sensitive electronics testing or battery charging. The built-in overvoltage, overcurrent, and short circuit protection provide essential safety for both the unit and connected devices. Weighing only 0.8kg, this compact supply is easy to move around the lab or workshop.

Features and Construction

Designed for precise power delivery, this supply combines solid construction with clear monitoring and multiple safety layers.

Output and Accuracy

The supply provides an adjustable output range of 0-30V and 0-5A, with accuracy rated at ±0.1% for both parameters. This level of precision makes it suitable for charging lithium-ion battery packs, powering prototype circuits, or running benchtop experiments. The 150W power budget handles moderate loads without strain.

Protection Systems

Overvoltage protection prevents voltage spikes from reaching your equipment. Overcurrent and short circuit protection automatically cut output in the event of a fault, reducing risk of damage. The protection level is rated 5, indicating solid safety margins for typical laboratory use.

Display and Controls

A bright LED display shows real-time voltage and current readings, allowing continuous monitoring. Front-panel knobs or buttons (not specified) let you adjust settings quickly. The unit is available with CN, EU, or US mains plug options, selectable at purchase.

Uses and Placement

This power supply fits a range of environments from hobbyist workbenches to professional electronics labs.

Laboratory and Educational Use

Students and technicians can rely on the stable output and accurate metering for experiments, component testing, and circuit prototyping. The low weight (0.8kg) makes it easy to store or move between stations.

Battery Charging and Repair

Use it to charge lead-acid, NiMH, or Li-ion battery packs with adjustable voltage and current-limiting capability. The protection circuits help prevent overcharging or reverse polarity damage when used correctly.

General Electronics Work

Power breadboard circuits, test motors, or run small DC loads with confidence. The ±0.1% accuracy ensures repeatable results when measuring component behaviour.

Benefits and Buying Value

This power supply offers practical advantages for daily use without overpromising.

Reuse and Maintenance

The rugged metal casing and fan ventilation (implied by design) support long operating sessions. Keep the air intakes clear and store in a dry environment. No specialist maintenance is required beyond basic cleaning of the case and connectors.

Why Choose This Product

For laboratory-grade accuracy and multiple protection features in a portable form factor, this DC regulated supply delivers solid performance. The ±0.1% precision and three protection modes make it a dependable tool for charging, testing, and experimentation.
