The Keysight 60504B is a 600 W DC electronic load module designed for evaluation and testing of DC power sources within compatible mainframes. It operates across 3 V to 60 V with current ranges from 0 A to 120 A, supporting constant current, constant voltage, and constant resistance operating modes. The module includes a programmable transient generator, analog voltage control for load adjustment, and comprehensive protection against over-current, over-voltage, over-power, over-temperature, and reverse polarity conditions.
