Laboratory DC Power Supply Voltcraft FSP-11312 — 13.8V, 12A, 165W

The Voltcraft FSP-11312 laboratory DC power supply provides a fixed 13.8 V output with up to 12 A current and a maximum power of 165 W. It is intended for bench testing, electronics repair and prototyping where a compact, rated and regulated supply is required. The unit supplies a stable DC voltage suitable for powering automotive electronics, small devices and test circuits, and is designed for use in workshops, educational labs and hobbyist workbenches.

Advantages

The supply delivers regulated 13.8 V output with current limiting up to 12 A, ensuring stable operation of connected loads and protection against overload. Its compact footprint and solid construction make it suitable for repeated bench use. The device offers predictable thermal and electrical behaviour for accurate troubleshooting and component testing. Simple front-panel connections and clear markings reduce setup time in routine testing tasks.

Suitable for

• Powering 12 V automotive modules and control units during bench tests
• Electronics repair and fault tracing on small consumer and industrial circuits
• Prototyping and powering single-board projects and sensors
• Laboratory experiments requiring a stable 13.8 V supply
• Hobbyist workbench use for testing batteries, chargers and low-power motors

Key specifications

• Nominal output voltage: 13.8 V DC
• Maximum output current: 12 A
• Maximum output power: 165 W
• Voltage regulation: fixed regulated output suitable for bench work
• Current limiting: built-in protection to prevent overcurrent
• Form factor: compact bench-top design suitable for workbench placement

How to use

Place the power supply on a stable, ventilated surface and connect the output terminals to the device under test using appropriate cabling and connectors rated for the required current. Set the unit to deliver the fixed 13.8 V output and ensure the load does not exceed 12 A. If a connected device draws excessive current, the built-in current limiting will engage; identify and correct the overload before continuing. Observe normal electrical safety practices, disconnecting power before making or changing connections.

Usage recommendations

Maintain adequate ventilation around the unit during high-load operation, use appropriately rated leads and fuses, and verify connections before switching on. For intermittent high-current testing, limit duty cycle to avoid overheating and allow cooling periods as needed.
