FT8100 series super high power feeding DC electronic load

FT8100 series super high power feeding type DC electronic load, mainly used in charging piles, power batteries, generator sets, power supply detection and aging. The FT8100 is a new generation of power electronic detection system introduced by Faith's many years of electronic load technology. It adopts the grid-connected feedback principle and the all-digital vector control technology of DSP real-time processing. It can perform constant current, constant resistance and constant on DC equipment under test. Power, and its sequence testing. When the function, performance, and aging test of the device under test are completed, the energy is returned to the grid. Not only greatly save energy loss, but also make the equipment energy density higher, the test is more stable and reliable.

Functions & Advantages

Operating mode:

The FT8100 has a constant current, constant resistance, and constant power mode to meet different test requirements. In constant current mode, the load always consumes a constant current regardless of the input voltage. The working curve is shown in Figure 3-1.

1 Constant current mode

 

负载电流:Load current         设定电流:Set current        输入电压:Input voltage

 

In the constant resistance mode, the load is equivalent to a constant resistance, and the input current is adjusted as the input voltage changes. The working curve is shown in Figure 3-2.

2 Constant resistance mode

 

负载电流:Load current         设定电阻:Setting resistance        输入电压:Input voltage

 

In constant power mode, the load will consume a constant amount of power. The input current is linearly adjusted as the input voltage changes to ensure that the power consumption is constant. The operating curve is shown in Figure 3-3.

3 Constant power mode

 

负载电流:Load current         设定功率:Set the power        输入电压:Input voltage

 

 

Sequence function:

The FT8100 has a sequence test function that simulates the timing changes at the input based on user-edited sequence parameters.

The sequence step parameters include: the function of each step, the set value and the delay time. The electronic load can store up to 6 sequence files, each of which can take up to 15 steps. The single step delay can be set to a maximum of 600 minutes. The figure shows a sequence of 5 steps and 2 loops.

3- 4 Sequence test

The user can set the number of times the sequence is executed cyclically (0 to 9999). When the number of executions is set to 0, it indicates an infinite loop.

 

Operation interface:

The FT8100 has a color touch screen operation interface. Users can easily view load operation information through the touch screen and implement various test functions, including: controlling load operation, displaying real-time operation data, displaying fault information, adjusting test functions and parameters, viewing history records, etc. . The interface diagram is as follows:

Power test:

The DC power supply, electric charging pile and other equipment to be tested will connect the corresponding power harness and communication harness to the FT8100 series of energy-feeding loads. The user can simply configure and start the FT8100 feed-loading touch screen to realize the function of the device under test. Performance and aging test as shown:

 

 

Feeding effect:

       The typical efficiency curves of the FT8100 series of energy-feeding loads are as follows:

 

        According to the curve above, we take the input power 110KW, the input voltage is 600V as the reference point, and see that the feedback efficiency exceeds 95%. After deducting the working power of the equipment, the power fed back to the grid exceeds 100KW, that is, the power saving exceeds 100 degrees per hour.
