Laboratory Power Supply Voltcraft FSP-1134 13.8 V DC 4 A

Voltcraft FSP-1134 is a laboratory DC power supply that provides a fixed 13.8 V output with a maximum current of 4 A. It is intended for bench testing, electronics repair and prototyping where a stable low-voltage DC source is required. The unit features a compact enclosure, a clear front-panel layout with output terminals and control elements, and engineered regulation to minimise voltage fluctuations under varying loads.

Advantages

The power supply delivers a constant 13.8 V output with up to 4 A current capacity, offering reliable performance for small devices and circuits. Its compact size and straightforward front-panel controls simplify setup and operation on crowded benches. Built-in regulation and thermal design contribute to stable voltage under typical laboratory and workshop conditions, while fixed-voltage operation reduces the need for frequent adjustments.

Suitable for

• Bench testing of small electronic modules and assemblies
• Repair and maintenance of radios, chargers and low-voltage devices
• Prototyping and breadboard experiments requiring a 13.8 V DC source
• Educational lab use where a simple, fixed-voltage supply is needed

Key specifications

• Output voltage: fixed 13.8 V DC
• Maximum output current: 4 A
• Output type: regulated DC
• Form factor: compact benchtop enclosure
• Interface: front-panel output terminals and control elements

How to use

Place the unit on a stable bench surface and ensure adequate ventilation around the enclosure. Connect the device under test to the front-panel output terminals observing correct polarity. Power the supply from a suitable mains source and switch it on; the supply provides a fixed 13.8 V output and will deliver up to 4 A as required by the load. Monitor the connected device and the supply for normal operation, and disconnect the load before moving or storing the unit.

Recommendations

Use short, appropriately rated leads for connections and verify polarity before applying power. Avoid continuous operation at maximum current for extended periods without ensuring sufficient ventilation. For sensitive electronics, add transient protection or additional filtering if required by your application.
