UNI-T UDP6721 Programmable Switching DC Power Supply

From the shop's description

UNI-T UDP6721 Programmable Switching DC Power Supply The UNI‑T UDP6721 is a single‑output, programmable switching DC power supply providing 0–60 V and 0–8 A (180 W) with fully digital control. Its compact chassis (87 × 174 × 255 mm) houses a high‑definition 2.8″ TFT LCD and a rotary encoder plus dedicated keys for rapid voltage and current adjustment. Remote‑sense terminals (S+, S–) compensate for lead‑line losses, ensuring precise load voltages over long cables. The unit interfaces via RS‑232 using SCPI commands for seamless integration into automated test systems, and includes upper‑computer software for real‑time monitoring, logging, and trend analysis. Protection mechanisms adjustable over‑voltage, over‑current, and over‑temperature thresholds automatically disable output upon fault. Intelligent fan control adjusts cooling airflow to minimize noise and extend component life. Advanced List and Delayer modes allow programming up to 48 sequence steps for time‑based or on/off cycling, while three memory banks (M1–M3) each store 200 presets (600 total) for one‑touch recall. With low ripple and noise, fine 10 mV/1 mA resolution, and software calibration, the UDP6721 balances versatility, precision, and reliability in a cost‑effective bench-top instrument ideal for R&D, production, and maintenance environments.
