Features coarse and fine voltage/current adjustment, clear display and protections to help when powering circuits and prototypes.

## Long description

Unit MIE0397 is a compact laboratory power supply providing an adjustable DC output from 0 to 30 V and a current range up to 5 A. Designed for bench testing, electronics development and repair, this model offers stable voltage regulation, current limiting and intuitive controls for precise setting of voltage and current. The front panel includes coarse and fine adjustment knobs and a clear display to monitor output values during experiments and prototype powering.
Advantages
The power supply delivers reliable, low-ripple DC output suitable for sensitive electronics and circuit tests. Coarse and fine adjustment controls allow accurate voltage and current setting, while built-in current limiting protects devices from overcurrent conditions. Its compact footprint makes it convenient for crowded workbenches and educational environments, and the clear front-panel display simplifies monitoring and adjustment during use.
Suitable for
Electronics prototyping and development
Component testing and bench measurements
Repairing and diagnosing electronic equipment
Educational labs and student projects
Key specifications
Output voltage range: 0–30 V DC
Output current range: 0–5 A
Adjustments: coarse and fine voltage/current knobs
Display: front-panel readout for voltage and current
Protection features: adjustable current limiting and overcurrent protection
Form factor: compact bench-top design
How to use
Connect the supply to the mains according to the local safety regulations and switch on the unit. Before connecting the load, set the desired voltage using the coarse and fine knobs, then set the current limit to a safe level for the device under test. Attach the load to the output terminals, monitor the display for voltage and current readings, and adjust as required. If the load draws more current than the set limit, the supply will enter current-limiting mode to protect the circuit.
Usage recommendations
For accurate measurements, allow the power supply to warm up for a short period after power-on. Use appropriate leads and connectors rated for the expected current, and verify polarity before connecting sensitive components. When testing unknown circuits, start with a low current limit and increase gradually.
