The Agilent/Keysight 6281A is a regulated benchtop DC power supply delivering 10 W across a 0 to 7.5 V, 0 to 5 A output range. It operates in both constant voltage (CV) and constant current (CC) modes, providing metered readback and front-panel control with coarse/fine adjustment capability. The unit features programmable output via analog control inputs (0 to –5 V for voltage, 0 to +5 V for current at 30 kΩ input impedance) and integrates overvoltage, overcurrent, and over-temperature protection with auto-restart functionality.
