UNI-T UDP6720 DC Power Supply
The UNI‑T UDP6720 is a single‑channel, switching DC power supply delivering up to 60 V and 5 A (100 W) with fully digital control and high efficiency. Its compact footprint (87 × 174 × 255 mm) belies a robust feature set designed for laboratory and industrial bench-top applications. A 2.8‑inch full‑color TFT LCD provides intuitive, multi‑parameter readouts, while a rotary encoder and dedicated keys allow rapid adjustment of voltage and current. The UDP6720 supports remote sensing (S+, S– terminals) to compensate for voltage drops on long leads, ensuring accurate load voltages. It offers SCPI‑compliant RS‑232 communication for integration into automated test systems, complete with upper‑computer software for real‑time data logging and trend analysis.
Protection features include adjustable over‑voltage, over‑current, and over‑temperature thresholds, automatically disabling output upon fault. Intelligent fan regulation minimizes acoustic noise and extends component life. Advanced functions such as List and Delayer modes enable programming of up to 48 sequence steps with timing and on/off control, while three memory banks (M1–M3) store up to 200 presets each (600 total) for instant recall.
Overall, the UDP6720 combines versatility, precision, and programmability in a high‑reliability, cost‑effective package.
