In addition, short circuit test is one of the necessary test items for power supply test, and the short circuit simulation function provided by the 63200E series can effectively solve the application needs of power supply test and automation test.

Through the front panel VFD display and knob, it is easy to operate and set up the 63200E series electronic loads, and it can also be remotely controlled wirelessly or wirelessly through Ethernet, USB, and GPIB communication interfaces.

The built-in PWM fan speed control can effectively reduce the noise caused by fan rotation. With over-current, over-power, over-temperature protection and over-voltage and positive/negative reverse alarm mechanisms, the 63200E series can greatly improve product reliability and is a reliable product for engineering test and automatic test system integration.

The 63200E series has constant voltage, constant current, constant resistance, constant power, and constant impedance modes of operation to meet a wide range of test requirements. For example, Constant Current and Constant Resistance modes can be used to test a voltage source to verify that the output voltage remains stable under different load conditions. For battery chargers or charging posts, constant voltage mode can change the output voltage of the charger or charging post to ensure that the charger or charging post has the correct charging current at the set output voltage. When the object to be measured is a battery, the electronic load can be transformed into a simulation of the pulling behavior of electronic equipment. Many battery discharge applications, power consumption, etc. can be analyzed by simulating the pulling behavior of the electronic load, and the fixed-power mode is one of the best choices for simulating the pulling behavior of electronic equipment.

To meet the performance requirements of power supply components for transient signals and dynamic response, the 63200E series provides high-speed, programmable dynamic loads, etc. The following figure shows the programmable parameters: set current light/heavy load alignment, T1 & T2, and actuation times. The following figure shows the programmable parameters: set current light/heavy load alignment, T1&T2, climb rate/decline rate, and number of actuations. 63200E series, when the load current varies continuously, the internal monitoring mechanism and circuits can minimize current waveform distortion, and the dynamics can be varied up to 2.5kHz.

Users can set the number of repetitions for light/heavy loads in the Dynamic Pull Mode, ranging from 1 to 65,535. When the set number of repetitions is set to once, the load current will be pulled in one pulse of current, which is ideal for applications such as testing the instantaneous high-current tolerance of fuses, switch assemblies, coaxial cable wires, relays, and batteries.

As there are many capacitors on the motherboard, in order to avoid charging the capacitors on the motherboard when the server power supply is turned on, and generating an inrush current that triggers the power supply's over-current protection mechanism and prevents it from powering on smoothly, the power supply needs to undergo a capacitive load power-on test, and therefore the 63200E series provides a constant impedance load mode to meet the needs of this test.

Constant impedance pull mode is different from constant current and constant power pull mode. Constant impedance mode simulates the actual inductive impedance, impedance, capacitive impedance and load to pull load, so the pull current is closer to the real situation. This waveform shows the simulated voltage and current waveforms of a switching power supply under capacitive load.

The 63200E series has built-in 255 programmable load sequences for users to simulate a variety of different real-world load pulling conditions. A single sequence (Sequence) load repetitive pull load and all the sequence load repetitive pull load, the minimum time for each sequence is 100 milliseconds (ms), the resolution is 100 milliseconds, the following examples to illustrate the general common programmable timing applications.

1. Battery discharge and other applications (laptop computers, electric vehicles, and electric locomotives), simulating a variety of different dynamic pull current waveforms, i.e., providing dynamic current simulation with more than two current qubits or a one-time pull simulation (for a single-channel output of the object to be measured)
2. Power Supply Mixed Load Modulation (for DUTs with multiple channel outputs)
3. Load Simulation for Fuel Cell Life Cycle Testing

The 63200E series provides four sets of self-defined shortcuts for users to access the desired operation modes more quickly, and to change the definition of the shortcuts, just long press the shortcuts for 2 seconds.

The 63200E series has 5 heights, 12 powers and 3 voltages, totaling 36 models. With high power density design, it subverts the concept of high power electronic loads being large and inconvenient to move, which can save a lot of space for the laboratory, and at the same time, it can easily solve the space problem when updating the electronic loads for the automatic test system.

The 63200E series has precise measurement accuracy, with high, medium and low load operation and measurement gears, built-in high-precision A/D converter, voltage, current and power measurement specifications up to 0.02% +0.02%FS, current 0.1% +0.1%FS and power 0.1% +0.1%FS accuracy, respectively. TP3TFS. Highly accurate measurements are indispensable for measuring the efficiency of the object to be measured and other important parameters.

The 63200E series is equipped with an intelligent master/slave control mode, which allows all models with the same voltage specification to be connected in parallel (master/slave control) to achieve the required current and power when the load power demand increases. When set to master/slave control mode, all the electronic loads set to master/slave control will become a single load. Users only need to program the load current on the master load, and the master load will automatically calculate and distribute the current to the other slave loads, which can greatly simplify the user's operation steps. All models can be integrated into a standard 19" wide rack (as shown in the picture on the right) to save space, and the 63200E is equipped with a USB interface (standard), an optional GPIB interface, and an optional Ethernet interface, which allows users to perform remote control and other automated test applications.

The 63200E is specially designed for battery discharge test, providing users with three discharge modes: constant current, constant resistance and constant power mode for steady state discharge, and by setting the cut-off voltage and stopping time (1 sec~100,000 sec), the electronic load can be correctly stopped to ensure that the battery will not be damaged due to over-discharge. In addition, in terms of measurement, it can measure the battery's discharge capacity (WH, AH) and total discharge time. Example: When Load ON is pressed to start pulling load, the internal timer of 63200E series will start counting until the battery voltage drops to the set cut-off voltage or Load OFF is pressed to stop pulling load, then the timer will stop counting. The battery discharge test function can also be used for ultra capacitor discharge time test and other similar applications.

DC charging piles are indispensable equipment in the EV-related market. The 63200E series of high-power DC electronic loads come in a wide range of power levels, from 2kW to 24kW, and operating voltages up to 1,200V. For functional testing of DC charging piles, the 63200E provides sufficient modes and functions to help R&D units conduct functional tests, QA units conduct verification tests, and even integrates with the 8000 system to help production lines produce products quickly. The 63200E can also be integrated into the 8000 system to help the production line to produce quickly.

The 63200E can also be used to simulate the battery in the test section of the vehicle charger. When the vehicle charger starts to charge the battery in constant current (CC) mode, the 63200E can be set to pull the load in constant voltage (CV) mode, and once the vehicle charger enters into the constant voltage (CV) mode to float charge the battery, the 63200E needs to be reset to the constant current (CC) mode for pulling the load.
