UNI-T UTL8512 Programmable DC Electronic Load
The UNI-T UTL8512 is a bench-grade programmable DC electronic load built for repeatable, instrumented evaluation of power sources. As a user-driven load, it draws controlled current, power, resistance or voltage from a device under test and converts that input into precise, measurable electrical stress. Operators use the instrument to exercise supplies across intended operating points, observe responses and collect time-stamped data for validation and troubleshooting.
Designed around an easy-to-read color display and a physically accessible front panel, the UTL8512 lets engineers program complex test sequences (lists, dynamic pulses and dual-mode profiles), capture screenshots to USB, and stream results to a PC for logging. Its internal logic handles measurement timing, waveform generation and safety interlocks so the operator can focus on test methodology rather than low-level control. The device also supports remote sense and an analog/current-monitor output for integration with external instruments.
In routine use the UTL8512 serves as a deterministic load it repeats the same programmed stress precisely, helps expose instability or protection behavior in supplies, and delivers measurement-grade readback with high resolution and fast sampling. Built-in protections and an intelligent cooling strategy let it run extended test sequences while protecting both the load and the unit under test, making it a practical tool for lab, production or R&D workflows.
Features:
- Programmable multi-mode loading (CC / CV / CR / CP).
- Dynamic, list and dual-mode sequence capability for complex tests.
- High-resolution measurement with on-device screenshot and file save to USB.
- Remote sense and current-monitor output for precise measurements and external logging.
- Multiple protection functions (OVP / OCP / OPP / overheat / reverse-polarity).
