Global Test Solutions (Escondido, CA) has launched the DL Series electronic direct current (DC) loads from NF Corporation with high-speed feedback control. Fast response times eliminate the common problem of overshoot and undershoot, better emulating a real-world electronic load. There are four DL Series electronic DC load models available, each with six modes combining constant voltage, current, and resistance, from 300W to 1000W. DL Series loads can be ganged together to configure up to a 10kW system. The input voltage is variable, with options up to 120V at 180A or 500V at 36A for the 1kW models. The DL Series simulates linear resistance when testing battery discharge, photovoltaic panels, or as a test load for DC power supplies. Their high-speed feedback control and fast slew-rate eliminate current overshoot and undershoot.
