Laboratory power supply Voltcraft FSP-11330 — 13.8 V, 30 A

The Voltcraft FSP-11330 laboratory power supply delivers a fixed 13.8 V DC output with a maximum current of 30 A. Built for bench, workshop and laboratory environments, this unit provides a stable voltage source for testing, servicing and powering a wide range of electronic equipment. Its single-output design focuses on delivering consistent 13.8 V power for automotive electronics, audio amplifiers, chargers and prototype circuits that require a reliable DC supply for diagnostics and extended operation.

Advantages

The compact, robust housing and straightforward front-panel connections make the device easy to integrate into test benches and repair stations without occupying excessive space. The regulated output maintains voltage stability under varying loads, reducing the risk of false test results or stress on connected components. Built-in protection features prevent damage from overload conditions and help ensure safe, continuous operation during long-duration tests.

Suitable for

• Automotive system testing and battery simulation
• Powering car audio amplifiers and head units
• Charging and testing 12 V lead-acid batteries and chargers
• Prototyping and bench testing of electronic circuits
• Service, diagnostics and component stress tests

Key specifications

• Output voltage: fixed 13.8 V DC
• Maximum output current: up to 30 A
• Single stabilized DC output suitable for continuous operation
• Front-panel DC output terminals for secure connections
• Thermally managed housing for stable operation under load

How to use

Install the power supply on a stable, ventilated surface and connect the load using the front-panel terminals, observing correct polarity. Switch the unit on and allow it to reach operating temperature; the fixed 13.8 V output is then available for powering devices or simulating vehicle electrical systems. Monitor current draw to ensure it remains within the 30 A rating, and disconnect the load before making wiring changes.

Recommendations

Use appropriately rated leads and connectors to handle currents near the 30 A limit, and provide adequate ventilation around the unit during prolonged high-current operation. For battery charging or sensitive electronics, verify connections and monitor voltage and current to avoid overcurrent or improper charging conditions.
