The HP/Agilent 6051A is a 600 W DC electronic load mainframe engineered for testing and characterizing DC power sources and components across R&D, manufacturing, and quality control workflows. Its modular architecture accepts up to two 60501B, 60502B, or 60503B load modules, or one 60504B or 60507B module, enabling flexible system configuration and expansion. The mainframe delivers stable load simulation with full HP-IB (IEEE-488) control, front-panel keypad operation, and real-time LCD metering of voltage, current, and power.
