High Power Density, Compact, Wide Voltage Range
The AN23600E series load features a wide range of voltage/current input for various testing scenarios, including high current and low voltage, or high voltage and low current. It boasts high power density, half the volume, and one-third the weight of traditional electronic loads.
Basic Mode
Built-in constant voltage (CV), constant current (CC), fixed point group, and constant power (CP) modes to meet various testing requirements.
FLEX Mode - Built-in Complex Impedance Network Power-on Mode
The input filter capacitor in the real load will cause a large inrush current at power-on. The parasitic resistance and inductance of the long internal lead will further distort the loading waveform. So its impedance will be equivalent to a complex impedance network.
The built-in complex impedance (FLEX) mode of the 23600E series is designed to simulate such loads and test the power supply under test's suitability. The four test parameters shown in the figure below are decomposed according to the characteristics of the real load in this mode. After power-on, the load current will follow the set impedance network.
BATY Mode - Dedicated Mode for Battery Test
The AN23600E series load provides three discharge modes for batteries: constant current (CC), constant resistance (CR), and constant power (CP), and can control the loading of the electronic load by setting the voltage threshold and test time (1~100000 seconds) to avoid damage to the battery caused by over-discharge. In addition, it provides discharge level indication.
BATY mode is also available for supercapacitors and other similar discharge tests.
LED Mode - Simulate LED Load Mode
The AN23600E series load has a built-in load mode to simulate an LED, loading as shown in the right figure to simulate the current of LED 0A before it is turned on, and the volt-ampere rise after turn-on. An electronic load is used to simulate the load to avoid light pollution and parameter instability caused by the LED strips and/or resistive loads.
