UNI-T UTL8511+ Programmable DC Electronic Load

UNI-T UTL8511+ Programmable DC Electronic Load

The UNI‑T UTL8511+ is a high‑precision, programmable DC electronic load tailored for demanding bench‑top and automated test environments. Built around a robust 150 W power stage and supporting up to 15 V/3 A operation, it features a large 4.3″ LCD that displays real‑time voltage, current, and power readouts, with waveform and ripple indicators for rapid signal‑integrity assessment. A 500 kHz synchronous sampling system and high‑performance DSP ensure stable resolution down to 0.1 mV/10 µA, enabling accurate characterization under both steady‑state and transient conditions.

The UTL8511+ offers four basic test modes constant voltage (CV), constant current (CC), constant resistance (CR), and constant power (CP) alongside dynamic (DYNA), over‑voltage (OVP), over‑current (OCP), time‑based, LED simulation, battery simulation, and LIST sequence modes for custom automated routines. Rear‑panel sense terminals compensate for lead drops, and RS‑232 (SCPI) plus HANDLER interfaces facilitate integration into ATE setups.

Comprehensive protection features including delay and immediate trip thresholds for overpower, over‑current, over‑voltage, and over‑temperature safeguard both the DUT and the load. Despite its advanced capabilities, the UTL8511+ remains compact (372 × 215 × 88 mm) and user‑friendly, making it ideal for R&D, QA, production line testing, and maintenance applications.
