Keysight / Agilent / HP N6700B Low-Profile Modular Power System (MPS) Mainframe

The Keysight N6700B Low-Profile Modular Power System (MPS) Mainframe is a 1U rack-mountable chassis that configures into a 1- to 4-channel DC power supply or electronic load system. It accepts up to four N6700 series DC power modules, enabling users to build custom power delivery solutions by mixing modules with different voltage, current, and power ratings. The mainframe delivers up to 400 W total output power and supports voltage combinations reaching 350 V and current combinations up to 100 A. Each module includes built-in voltage and current measurements, fast command processing, and programmable voltage slew rate control from maximum speed down to 10 seconds. Individual module sequencing with delayed turn-on/off is supported, scalable across multiple mainframes for complex test scenarios.
