    The T3EL15060P and T3EL50015P Series are single channel, 300 Watt Electronic Loads ideal for R&D, product validation and Q&A in a bench or automated environment for low to medium power applications starting from 60 mA, such as electronic components, batteries, portable chargers and power products.

    The T3EL Series has seven operating modes. Among them, the four basic operating modes are constant current, constant voltage, constant resistance, and constant power. Three other combined operating modes are constant current + constant voltage, constant resistance + constant voltage, constant power + constant voltage. Users can select operating modes based upon products’ test requirements. For CC mode the electronic load will sink a constant current according to the set current value; for CV mode the electronic load will attempt to sink sufficient current to control the source voltage to the programmed value; for CR mode the electronic load will sink a current linearly proportional to the input voltage according to the set resistance value; for CP mode the electronic load will initiate load power sinking operation (load voltage x load current) in accordance with the programmed power setting.

    To meet the requirements of different test conditions, the Static function is to sink a constant current; the Dynamic function is to periodically switch between two sink conditions, and the Sequence function is to provide tests for more than two sink conditions. The sequence function can be divided into Normal Sequence and Fast Sequence. Normal Sequence is the most flexible means of generating complex sequences, that can allow users to establish a set of changing current sink conditions based upon different sinking requirements (CC, CR, CV or CP mode) and time (adjustable range: 1 ms to 999 h 59 min 59 s in Normal Mode). Fast sequence allows time resolution of 25 us to be set for the smallest step. Setting parameters for multiple steps can simulate consecutive current changes of various real load conditions. For instance, while using an electronic load to test a power-driven tool’s power supply.

    The Soft Start function allows users to determine the rise time of the current sink by measuring the required time to reach the electronic load’s set current, resistance or power value. Setting a proper rise time for Soft Start will counter output voltage fluctuations caused by a DUT’s (power supply) transient output current. Generally DC loads do not have the soft start function that is built in to the T3EL Series.

    When conducting high speed current sink operation, the inductance effect on the cables connecting the electronic load and DUT will lead to transient voltage drop on the electronic load’s input terminals that will result in Voltage Non-monotonic increase. The T3EL Series soft start function not only allows the output voltage to follow a Monotonic increase, but also prevents inrush current and surge voltages that could damage the DUT. For instance, tests using a power supply, LED and a DC load (activate the soft start function) can prevent inrush current and surge voltages from causing damage to the LEDs.

    The built-in BATT Test Automation provides battery discharge applications with more flexible discharge stop settings as well as rise and fall Slew Rates for discharge current settings.

    The OCP, OPP test Automation for DUT’s (ex. Power Supply), provide users with high resolution measurement values to verify DUT’s activation point and provide users with measurement results to help them determine whether DUT’s actual over protection activation point meets regulations.

    The T3EL Series provides users with an analog control terminal to control the T3EL Series using an external voltage, external resistance and switch.
