The Keysight N5745A is a 750 W single-output programmable DC power supply engineered for automated test equipment and bench applications. This 1U rackmount unit delivers 0–30 VDC at 0–25 A with universal AC input (85–265 VAC), constant voltage/constant current operation, and integrated protection against overvoltage, overcurrent, and thermal faults. Remote sensing compensates for wiring losses to maintain load accuracy. The instrument supports GPIB, LAN, and USB 2.0 interfaces with full LXI Class C compliance and includes a built-in web server for browser-based control.
