The 4.3-inch LCD color display provides users with a clear and intuitive visual experience;
Resolution up to 0.1mV/1mV/ 0.1mA to accurately test the performance of the device under test;
Timing control list programming for accurate, high-speed simulation of complex changing currents;
Equipped with USB/LAN/RS232 interfaces, supporting SCPI protocol, convenient for data interaction and remote control;
OCP/OPP test, the instrument automatically captures the OCP and OPP points and determines whether the test result exceeds the set specifications;
With voltage rise/fall time test function and ripple measurement function;
Voltage and current measurement rate up to 100KHz;
Remote measurement terminals are provided to compensate for voltage drop across the line and improve remote measurement accuracy;
Four operating modes: constant voltage/current/resistance/power, easy to simulate a variety of characteristics of loads;

Waveform display and record

It can real-time display and record the change process of current, voltage, resistance and power value under various modes, and generate dynamic curve for storage.

CC: Constant Current

Regardless of the input voltage change, the load will pull load according to the set current, making the load work in constant current mode.

CV: Constant Voltage

In this mode, the load maintains the input voltage at a constant value by pulling the load current.

CR: Constant Resistance

In this mode, the load is equated to a constant resistance; variable from 0.1 ohms to 7500 ohms.

CP: Constant Power

This mode will pull the load at a constant power.

Voltage rise/fall time test function and ripple measurement function

It can accurately assess the dynamic response and stability of the power supply, quickly locate transient anomalies and ripple exceeding the standard, and improve the debugging efficiency and reliability of power supply design.

OCP/OPP Test

The instrument automatically captures OCP and OPP points and determines whether the test results are out of the set specifications, saving the user's verification time for design verification and system generation.

List Features

The loads can accurately simulate complex arbitrary current patterns at high speeds, allowing for precision testing with multiple aligned loads.

Battery Function

Automatically stops the test when the battery drops to the end of voltage or has been discharged to the end of capacity or reaches the end of time. Ensures that the battery is not over-discharged and damaged.

Tran Function

This function can be used to test the dynamic characteristics of the device under test by switching the electronic load between two set parameters (A value and B value). Dynamic test modes can be categorized into continuous mode, pulse mode and flip-flop mode.

CR-LED

Increase the setting of diode on voltage, more realistically simulate the working principle of diode, to avoid the traditional CR mode voltage and current instability generated by the vibration.
