NI RMX-4125 is a rack-mount programmable DC power supply identified by NI as a 1U, full-width, single-channel instrument. NI specifies this exact model as “RMX-4125 1U DC power supply, 1500W, 0 to 80VDC, 0 to 56A,” making it the 80 V / 56 A member of the RMX-412x 1500 W family rather than a generic family label. NI also lists orderable part number 784766-01 for this model. https://www.ni.com/en/shop/hardware/power-supplies/model-rmx-4125 https://www.ni.com/pdf/product-flyers/rack-mount-programmable-power-supplies-and-loads.pdf?srsltid=AfmBOorA0-ffpPyP-r4I_cBWRVIPO-kdpzV9SxjWK3ND9ZUgeLXdazj1
For automated test and bench integration, NI calls out USB, LAN, RS232, and analog control options on the RMX-4125 product page. NI’s RMX-412x Communication Interface Help further states that supported models, including RMX-4125, can be remotely controlled through RS232C, USB, and LAN interfaces. This makes the RMX-4125 suitable where programmable source control must be integrated with host-based test software or networked instrument setups. https://www.ni.com/en/shop/hardware/power-supplies/model-rmx-4125 https://www.ni.com/en/support/documentation/supplemental/18/rmx-412x-communication-interface-help.html
Within the RMX-412x documentation set, NI states that RMX programmable power supplies can operate as constant-voltage (CV) or constant-current (CC) supplies. The family user manual explicitly includes RMX-4125 among supported instruments and identifies it as a 1500 W, 0 VDC to 80 VDC, 0 A to 56 A programmable power supply device. NI also provides a separate Safety Information and Installation Guide covering the 1500 W models RMX-4124, RMX-4125, RMX-4126, and RMX-4127. https://www.ni.com/docs/tr-CY/bundle/rmx-412x-features/page/user-manual-welcome.html https://download.ni.com/support/manuals/376814b.pdf
