The Keysight EL34243A is a dual-input, 600 W bench DC electronic load engineered for rigorous power source characterization and validation. Each isolated channel independently operates at up to 300 W, 150 V, and 60 A, or channels combine in parallel mode to deliver 120 A at 600 W total. The instrument provides four load modes – Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP) – enabling precise emulation of diverse load characteristics.
