Bench Power Supply

A bench power supply is a laboratory-grade electronic device that provides stable, adjustable DC voltage and current to power circuits and electronic components during development, testing, and repair work. It typically features precise voltage and current controls, digital or analog displays for monitoring output parameters, and built-in safety features like overcurrent and overvoltage protection. Unlike wall adapters or batteries, bench power supplies allow real-time adjustment of output parameters and provide clean, regulated power essential for reliable circuit operation and troubleshooting.
