UNI-T UTL8512A+ Programmable DC Electronic Load

Description

UNI-T UTL8512A+ Programmable DC Electronic Load The UNI-T UTL8512A+ Programmable DC Electronic Load is a high-performance programmable DC electronic load designed for precise testing of power supplies, batteries, and electronic components. It supports multiple operating modes (CC, CV, CR, CP) and dynamic testing capabilities, enabling realistic simulation of load conditions. With high resolution and fast dynamic response, it is suitable for R&D, production testing, and quality assurance environments. It also features remote control via RS-232 and compact rack-mount form factor for lab integration. Features 150 V / 30 A / up to 400 W load capacity. Synchronous sampling of 500 kHz, 10Hz, 10uA, 0.1 mV stable resolution output. Multiple operation modes: CC, CV, CR, CP. Adjustable current slew rate (0.0006 A/µs to 3 A/µs). Dynamic mode (DYNA) of 50 kHz pull load, the waveform of current and voltage peak can be observed directly (UTL8500X+ series), Vpp, Ipp measurement. Realistic simulation of LED function. Supports OCP test and maximum power test. Supports time measurement (TIME). Supports OVP test. Supports intelligent and programmable automated list test (LIST). Protections of over-voltage/under-voltage/over-current/over-power/overheat/anti-reverse connection. 4.3 inch LCD, all the test results at a glance. Screenshot function with list storage & recall. RS-232 interface for remote control and automation. Remote sense terminals for accurate voltage measurement. Compact ½ 2U rack-mount design.
