Smart Bench Power Supply

A custom-built, high-precision laboratory bench power supply designed for electronics prototyping and component testing. Engineered from scratch combining custom 3D CAD modeling, buck converter power regulation, and integrated thermal management.

Key Features & Technical Details

• High-Precision Regulation: Utilizes multi-turn potentiometers integrated with buck converter circuits to deliver fine, highly precise voltage and amperage adjustments with minimal output ripple.
• Custom 3D-Printed Enclosure: Designed in Fusion 360 to ensure zero-clearance component mounting, internal structural rigidity, and clean external panel geometry.
• Effective Thermal Management: Features dedicated internal airflow channels and active cooling heatsinks to maintain optimal operating temperatures under high load conditions.
• Real-Diagnostics: Dual digital LED panel meters provide continuous visual feedback for voltage and current output levels.
