UNI-T UTL8511B+ DC Electronic Load Battery Test

From the shop's description

UNI-T UTL8511B+ DC Electronic Load Battery Test The UNI-T UTL8511B+ is a programmable DC electronic load designed for professional testing of high-voltage DC sources. It supports input voltages up to 500V, currents up to 15A, and power up to 200W, making it suitable for evaluating power supplies, batteries, chargers, DC converters, and other power electronics. The instrument provides precise control over the applied load and allows users to monitor the behavior and performance of the device under test. The UTL8511B+ provides constant current, constant voltage, constant resistance, and constant power modes, together with dynamic testing, battery discharge testing, OCP/OPP testing, OVP testing, ripple measurement, short-circuit testing, and automated list testing. Its battery-test function can record the discharge process and provide a battery discharge curve, making it useful for evaluating battery capacity and discharge characteristics.
