The UDP6721 is a single-channel 180W programmable DC switching power supply with a 3.0 power-ratio architecture that operates within a 0–60V, 0–8A, 180W output envelope. It is designed for product development, board debug, battery simulation, and production testing. A 2.8-inch full-color LCD shows voltage and current simultaneously, while 10mV/1mA resolution, remote sense, RS-232, and full SCPI control support automated benches. List/delayer functions, a smart fan, 600 stored settings, and OVP/OCP/OTP protection support both interactive and scripted workflows.
