The Extech Digital DC Power Supply is an excellent choice for the science classroom. Its output is adjustable from 0-18 V at 0-3 A. It provides constant current or constant voltage modes and has overload and short circuit protection. The output terminals are shrouded banana jacks, and connecting cables are provided. The front panel contains digital voltage and current meters, so you won’t need additional metering in a typical experiment. This power supply will work perfectly with the activities in our physics lab manuals that require DC power.
