Laboratory Power Supply Voltcraft FSP-1138 – 13.8 V DC, 8 A

The Voltcraft FSP-1138 is a laboratory power supply that provides a fixed 13.8 V DC output with a maximum current of 8 A. Designed for bench testing, electronics repair and powering 12 V systems, it supplies stable DC voltage suitable for prototypes, automotive electronics and general lab equipment. The compact housing and straightforward controls make the unit practical for workshops, service benches and educational labs where reliable, continuous 13.8 V power is required.

Advantages

The unit maintains a consistent 13.8 V DC output under varying load conditions up to 8 A, reducing the need for manual voltage adjustments during testing. Its compact form factor saves bench space while providing terminal connections and indicators for quick verification of output status. Built with basic protection measures, the supply offers steady performance for routine measurement, repair and powering of 12 V devices.

Suitable for

• Bench testing of electronic circuits and prototypes
• Repair and maintenance of automotive and 12 V equipment
• Powering radios, small DC motors and accessories that require stable 13.8 V
• Educational laboratories and hobbyist workstations

Key specifications

• Output voltage: fixed 13.8 V DC
• Maximum output current: 8 A
• Power delivery suitable for continuous operation within rated current
• Compact benchtop form factor with terminal output connections
• Basic protection and status indication for safe everyday use

How to use

Place the power supply on a stable, ventilated bench surface and connect the output terminals to the device under test using appropriate gauge leads and secure connectors. Ensure the mains input is compatible with local supply and switch the unit on. Verify the output indicator before connecting sensitive equipment. Operate within the rated 8 A maximum current; if testing unknown loads, monitor current draw and temperature during initial operation to avoid overloading.

Recommendations

Use appropriately rated cables and connectors for currents up to 8 A and keep adequate ventilation around the unit during continuous operation. For long-term powering of sensitive electronics, confirm polarity and measure the output voltage under load. If the connected device draws near the maximum current, allow periodic cool-down intervals and follow safe handling practices for laboratory equipment.
