| Feedback load function

FTB9000 series products have the feedback load function, which can return the energy of the equipment under test to the factory Intranet for direct use, rather than dissipate it as heat. Its energy feedback conversion efficiency is as high as 95%, which can not only greatly reduce the cost of electricity for users, but also avoid the use of air conditioning and other refrigeration systems and reduce noise.

At the same time, when working as a feedback load, it has four basic working modes of constant current, constant voltage, constant power and constant resistance, which can meet a wide range of test needs.

|Battery charge/discharge test

Due to its unique bidirectional design, FTB9000 series has charge/discharge test function, which is suitable for various kinds of batteries and energy storage equipment charge/discharge test.

| CV and CC are preferred

When the power output is connected to the inductive or capacitive load, the output current or voltage will overshoot to a certain extent, which will trigger the protection of the device under test, or even damage the device under test. FTB9000 series with CV, CC output priority function to effectively inhibit the output overshoot and the impact.

CV priority
(high speed build voltage, current overshoot)

CC priority
(high speed build current, voltage overshoot)

| Double quadrant, wide range

FTB9000 series products have dual quadrant working characteristics, can be used as DC power output energy, and can be used as feedback load to absorb energy. At the same time, FTB9000 has a wide working range, with more than 3 times the wide range of output range, one power supply can cover more applications, saving costs for users.

| Sequence and waveform function

FTB9000 provides users with sequence editing functions for power supply interruptions, instantaneous drops, and other voltage and current changes. A total of 10 sequence files, each file 100 steps, support cycle, link to facilitate the realization of complex waveform output.

| Seamless switching of two-way current

FTB9000 automatic source load function, you can quickly and seamlessly switch automatically. The conventional DC power supply and load will produce a short step at 0A when the positive and negative current are switched, resulting in discontinuous current commutation. FTB9000 not only has the dual-quadrant working ability, but also has the high-speed current switching ability, which can realize the seamless connection of positive and negative current switching, effectively avoid voltage or current overshooting, and is widely used in the test of motor, battery pack, BMS and energy storage system.

|3U/18kW high power density

The FTB9000 series provides a high power density of 3U/18kW, with accurate output, fast response and low ripple noise. The wide range of voltage 80V ~ 2250V and current 25A ~ 4500A is suitable for every test and verification link from design to production process.

| Master/slave parallel function

FTB9000 series power supply provides master and slave parallel mode, supporting 10 power supplies of the same model for parallel operation, so that users can achieve more power expansion. When the parallel operation, the host automatically displays the parameters, and the slave automatically copies the set parameters of the host to achieve automatic current sharing.

| Photovoltaic array simulation function

FTB9000 series comes standard with feature-rich "Faith Power Demonstration Platform" with basic PV function for testing PV inverters. With the host computer demonstration platform, more test functions can be realized, such as dynamic MPPT, typical weather data, custom light/temperature change curve and so on. For more complex PV test functions, you can choose the Fiesta Solar PV Matrix simulation software.

| Battery simulation function (optional)

The FTB9000 has a unique current bipolar design, which can simulate the charge and discharge characteristics of the battery for various tests. Under the battery simulation function, users can edit battery files. The battery file mainly describes the characteristic curves of the battery capacity, open circuit voltage and internal resistance of the battery. After the battery simulation function is turned on, it will absorb current (charge) or output current (discharge) according to the external load, and adjust the output voltage to make the output voltage conform to the characteristic curve specified in the file.
