Keysight (Agilent) 6050A 1800 Watt Electronic Load Mainframe, 6 Slot

The Keysight (Agilent) 6050A is a 6-slot electronic load mainframe capable of dissipating up to 1800 watts. It accepts user-installable load modules for flexible system configuration, supporting either six 60501B/60502B/60503B modules or three 60504B/60507B modules. A single GPIB address provides integrated control and readback across all installed modules, enabling precise testing of power supplies, batteries, and other DC power sources.
