Calibration

This series Programmable DC electronic load provides three voltage ranges 200V/600V/1200V. Supports CV, CC, CR, and CP these 4 basic operating modes, as well as CV+CC, CV+CR, CR+CC these 3 complex operating modes. Full protection including OCP, OPP, OTP, over-voltage and reverse alarm. Support external control and monitor mode, the 0 to 10V input or output signal represent 0 to full range voltage or current. Provide OCP test, OPP test, and Short circuit simulation to effectively solve the application demands for power and automated testing. Built-in RS232, RS485, and USB communication interfaces, LAN&GPIB communication card is optional. Two or more loads can be connected in master-slave parallel mode to provide more power or current capacity. This series DC load can be applied to battery discharge, DC charging station, and power electronics, and other electronics products.

 

Color Touch Screen

This series programmable DC electronic load together with a large color touch screen provides simple and fast operation for customers. Real-time update of display input data, status, and graphical display make it more intuitive.

 

Multiple Operating Modes

This series programmable DC electronic load provides four kinds of basic operating modes including CV (constant voltage), CC (constant current), CR (constant resistance), CP (constant power), to satisfy a wide range of test requirements.

 

Adjustable CV Loop Speed

This series electronic load supports CV loop response speed setting to VerySlow, Slow, Normal, Fast, and very fast to satisfy different test requirements. This function may avoid the inaccurate measurement or testing fail caused by the response speed mismatch between the load and the power supply, which is possible to improve test efficiency and reduce costs on the equipment, time, and expenses.

 

Dynamic Load

This series of electronic loads can be switched quickly between different values in the same operating mode, including CC dynamic mode, CV dynamic mode, CR dynamic mode, and CP dynamic mode, CC/CR high-speed dynamic mode up to 50kHz. This function is suitable for the transient test of power supply, a test of battery protection characteristic and battery pulse charging, etc. Dynamic mode test has a continuous mode, pulse mode, and toggle mode.

 

Sine Wave Dynamic Load

This series of electronic loads support sine wave loading function which allows loading sine wave, can be used for impedance analysis test of fuel cells.

 

Dynamic Frequency Sweep Function

This series electronic load provides a unique constant current dynamic sweep to use frequency conversion to find out the UUT voltage of the worst case. This CC dynamic sweep allows the user to edit two load levels, start frequency, end frequency, step frequency, dwell, etc. The sampling rate is up to 500kHz, which make it can simulate different loading conditions for most test requirements.

 

Battery Discharge Test

This series electronic load has a battery discharge function and can perform discharge test under CC, CR, or CP mode. The DC load can set end voltage or time to stop loading correctly and make sure the battery is not damaged due to over-discharge. The user can set stop conditions, whenever met any condition, the load will stop loading and counting automatically. During the test, users can observe the battery's voltage, discharging time, and already-discharged-capacity.

 

Auto Mode

This mode allows automatically switches among CV, CR, CC, and CP modes. It is suitable for lithium-ion battery charger testing to get a complete V-I charging curve. This flexible auto mode also enormously improve test efficiency.

 

OCP/OPP Tests

This series of electronic loads provides OCP and OPP modes are mainly applied in over-current and over-power point tests. After the testing, the load can automatically judge the test result according to the set specifications. Take OPP testing as an example, the OPP provides ramped up power for the load to test the UUT voltage whether has reached trigger voltage level and to judge if the protection is acting normally or not.

 

List Mode

The list function allows users to create waveform files to automatically simulate various complicated loading conditions. The list mode has 10 files, by editing operating mode (including CC, CV, CR, CP, Short and ON/OFF), repeat times, total steps, setting the value of each step and step time, etc. This function can be applied to the testing of output characteristics and stability for power supply.

 

Master/Slave Control

This series electronic load provides the user with a Master/slave mode that supports parallel connection under different power and the same voltage and dynamically synchronized. In Master/slave mode, the user only needs to control the master one, the load current will be automatically calculated and downloaded to the slave loads. The Master/slave mode greatly simplifies the operation when increased power is needed.

 

External Control and Current/Voltage Monitoring

This series electronic load has an analog control interface to control the input voltage and current. The external signal 0 to 10V controls the sinking condition from 0 to full scale. Using the external control mode can simulate arbitrary waveform which is ideal for industrial control requirements. The 0 to 10V analog output signal of V-MON/I-MON terminals represent input to which the terminals belong from 0 to full range. An external voltmeter or oscilloscope can be connected to display input voltage/current change.
