Overview
The UDP6953B is UNI-T’s 600W programmable DC switching supply at the 150V class — the spec for SiC half-bridge characterization, fast EV charger DC-link emulation, and high-power solar inverter input stress testing. Auto-range output delivers up to 150V at reduced current, 10A at reduced voltage, or any combination within the 600W envelope from a single instrument.
Full programmable interface set: USB Device, USB Host, RS-232, RS-485, LAN with web control, and external analog I/O — with SCPI, Multi-SCPI, and Modbus RTU command support. Built-in 4½-digit DVM monitors a second voltage point on the DUT without an external instrument. Slope control configures rise/fall rates independently in voltage-slope (VSR) and current-slope (ISR) modes for soft start/stop. Remote sense (S+/S−) compensates for IR drop on the test leads. List mode and delayer functions program up to 512 voltage/current/time groups, stored to internal Flash or USB.
