Laboratory Power Supply Unit Unit UT-P3315-TFL-II — bench DC power source by Unit

The Unit UT-P3315-TFL-II laboratory power supply is a bench DC source intended for laboratory, educational and repair use. It delivers adjustable DC voltage and current for powering and testing electronic circuits, components and devices. The design focuses on stable output, accurate adjustments and safe operation to support bench measurements, prototyping and routine maintenance tasks where a dependable adjustable supply is required.

Advantages

This bench power source provides fine adjustment of voltage and current with stable regulation for consistent results during testing and measurement. It includes protections and a clear front-panel interface for straightforward operation in laboratory and workshop environments. The compact footprint and robust build enable reliable continuous use while maintaining measurability and repeatability for research, education and repair workflows.

Suitable for

• Powering and testing low- to medium-power electronic circuits and modules
• Educational laboratories and electronics training courses
• Repair benches for troubleshooting and component verification
• Prototyping and development work requiring adjustable DC supply
• Bench measurements and calibration tasks that need stable outputs

Key specifications

• Adjustable DC output voltage range suitable for typical bench electronics work
• Adjustable output current with current-limiting capability for component protection
• Clear front-panel controls for precise setting of voltage and current
• Stable voltage regulation to minimize output fluctuation under load
• Protection features to prevent overload and damage to connected devices
• Compact bench form factor designed for workshop and laboratory placement

How to use

Place the power supply on a stable bench surface and connect the device under test to the output terminals or binding posts following correct polarity. Switch on the unit and set the desired voltage using the front-panel control, then set the current limit to a safe value before applying power to the circuit. Monitor the output readouts during operation and adjust voltage or current as needed for measurement or testing. When finished, reduce output to zero and power down the unit before disconnecting test leads.

Usage recommendations

Use appropriate test leads and observe polarity to avoid damage. Always set the current limit below the maximum rating of the component or circuit being tested. Allow the unit adequate ventilation and avoid placing heat-sensitive items near air vents. For educational use, supervise learners when they connect circuits and adjust settings.
