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.

CCD Mode - Fast Dynamics and VPP Test

The AN23600E series load has a built-in high-speed dynamic loading test function, with dynamic changes up to 50kHz. The user can set the number of repetitions for a period (1~100000) or continuously perform dynamic loading. As shown in the figure below, you can set the current high/low loading value, loading time, rising/falling slopes, etc. During dynamic loading, the load also provides peak-to-peak voltage measurements at acquisition frequencies up to 500kHz.

CC Mode - Ultra-fast Loading Speed and Ultra-low Overshoot

The AN23600E load series provides ultra-fast loading. For example, AN23606E-1200-240 can provide 12A/us rising speed. In addition to rapid loading, the load's built-in digital controller can minimize the current rise waveform at full speed, reducing overshoot for the AN23600 series.

CV Mode - High-performance Controller with Adjustable Loop Speed

With more applications of constant current (CC) sources, this AN23600E(F) series DC electronic load features a built-in, optimized zero-compensation controller. While satisfying fast, stable, and accurate loading, the three adjustable loop speeds expand load adaptability. Unlike conventional integral-type lag control, an obvious advance predictive control link is evident in the right figure. The bottom is the current wave, and the pre-judgment of the power supply under test is completed first, so that the CV loading process can be completed quickly and stably.

LIST Mode – Series Loading

Up to 8 data groups can be edited via the built-in series test of the AN23600E load. 200 steps can be edited per group, and the execution time (0-100s) can be set for each step.

Various current waveform patterns are used in battery discharge, server, communication power, combined load modulation, and other applications, serving as an effective complement to dynamic current testing.

High Precision Measurement

This AN23600E series load provides three levels for voltage/current measurements. For example, AN23606E-1200-240 supports 150V/600V/1200V, covering low-, medium-, and high-voltage applications; the current is 24A/120A/240A, enabling accurate measurements across different applications. High-precision A/D and D/A chips, with accuracy of voltage 0.015%+0.015%F.S., current 0.04%+0.04%F.S., and power 0.1%+0.1%F.S.

Instantaneous Overpower Capability

The AN23600E series has an instantaneous 2x overload capacity, allowing the load to withstand short-term power levels exceeding the rated power.
Idea selection of impact products.
Users can select models based on the rated power of the power supply or battery, rather than on maximum power, low cost, and high adaptability.

Precisely Lock the Power Protection Point

An excessive output current/power from the source under test may cause damage. Therefore, most of the power sources under test have overcurrent/overpower protection: the output voltage is reduced or stopped when overloaded. So this kind of load provides test modes for this situation - Over Current Point, Over Power Point (OCP, OPP).

When the load detects that the voltage is less than or equal to the threshold after setting the loading circuit and threshold, the load stops, and the current/power at the time of protection is displayed on the screen; the result is judged against the protection point.

Visual Programming Software

Users can test using the PC software programming load. It will be troublesome to set the series test (List) via the load interface, but it can be set quickly via the graphical interface of the host, cooperating with the wave drawing, which is convenient for the testers.

Over Current Point, Over Power Point (OCP, OPP), the host will store the test results, process data automatically, and generate a test result report.

Acquire Data

The user can acquire the instantaneous voltage/current by sampling the load and synchronizing with the trigger source, and plot a waveform of data points using the host software. The test data can be exported to an Excel file.
