Multiple working modes

The FT68200A/E series has CC, CV, CR and CP modes to satisfy comprehensive test requirements.

Furthermore, the FT68200A series has CV+CC, CR+CC, and CP+CC compound mode. Users can set the current limit value according to their own test requirements to avoid over-current damage to the device under test. The CV+CC mode can be used to simulate battery charging characteristics, so as to test charging piles and car chargers and other similar products. CR+CC mode can simulate power supply voltage and current limit and accuracy test.

30kHz dynamic frequency sweep, Vpk+/- capture

The FT68200A/E series has a dynamic frequency sweep function, and the maximum frequency can be set to 30kHz. During the test, by adjusting the current load frequency, capture and record the peak voltage Vpk+, valley voltage Vpk- and corresponding frequency of the tested power supply in the whole process. It can effectively test the dynamic response of various power supplies at different frequencies.

1kHz data transmission rate

The FT68200A/E series provides users with a data transmission rate of up to 1kHz, that is, 1000 voltage and current data points per second, which facilitates applications such as waveform drawing and dynamic data analysis. In system integration applications, the host computer can use this feature for acquiring test data, avoiding the use of oscilloscope and high-speed current acquisition hardware, thus saves costs.

Instantaneous overpower loading capability

The FT68200A/E series electronic load has an instantaneous load capacity of 2 times the rated power. This greatly saves costs for instantaneous high-power testing environment. This function is suitable for testing situations such as DC motor start, power supply instantaneous overload, power battery instantaneous high-rate discharge, instantaneous load capacity test of power electronic devices, etc..

Time measurement

The FT68200A/E series has time measurement feature, which can capture external switching signals, and combine with voltage/current signals to test system response and action time. For pulse currents, it can test its pulse width. It is mainly used to test the switching time, holding time, rising edge and falling edge time of the power supply. It can also measure the fuse blowing time and circuit breaker response time.

Battery test

The FT68200A/E series electronic load has a battery test function. It provides three discharge modes: constant current, constant resistance, and constant power.

Users can set the cut-off voltage/time/AH, the discharge process shall terminate either condition is satisfied.  The load will record the AH and discharge time during the discharge process.

The FT68200A/E series uses the DC discharge method (DCR) to test the battery internal resistance and capacity.

Sequence

The FT68200A/E series electronic load provides sequence test function. It supports 20 sequence files, and each file with 100 steps, able to simulate more complex load changes in CC mode.

Sequence files can be linked, and sequence single step time can be set to 0.1ms ~ 99,999s.

Parallel

The FT68200A/E series electronic load supports master-slave parallel of up to 10 identical units.

External analog programming

Other devices can continuously control the load through an external voltage signal (DC or AC). The external voltage signal of 0～10V corresponds to 0～100% full-scale load current. This function is also suitable for various complex load waveforms test.
