An adjustable power supply with a broad output range, designed for versatile electronics work and testing. Variable output: Set the voltage to match a wide range of devices and experiments, reducing the need for multiple supplies. Stable regulation: Constant voltage and current control keep the output steady even as load resistance changes, protecting circuits and improving reliability. Clear display: A multifunction LCD shows voltage, current, power, capacity, energy, and elapsed time at a glance for easy monitoring. Durable, well cooled: Aluminum alloy housing with an integrated fan cooling system improves heat dissipation, extends service life, and maintains performance during long sessions. Compact and compatible: Benchtop form factor fits in tight workspaces and works with various DC devices requiring regulated power. Use scenarios: Prototyping and debugging microcontroller projects that require precise voltage and current limits. Lab tests for DC motors, stepper drivers, or amplifiers that need stable, monitorable power. Battery pack testing or charging experiments with controlled voltage and current profiles. This transformerstyle supply combines practical regulation, comprehensive monitoring, and builttolast materials for reliable daily use.
