Regenerative load function

FTB9000 series products have a regenerative load function, which can feed back the energy of the device under test to the factory intranet for direct use, instead of dissipating it in the form of thermal energy. Its energy feedback conversion efficiency is as high as 95%, which can not only greatly reduce the electricity cost of users, but also avoid the use of air conditioners and other refrigeration systems and reduce noise.

Seamless switch between sourcing and sinking

When conventional DC power supply and load switch between positive and negative currents, a short step will be generated at 0 A, resulting in discontinuous current commutation. FTB9000 not only has two-quadrant working ability, but also has high-speed current switching ability, which can realize seamless connection between positive and negative current switching, effectively avoid voltage or current overshoot, and is widely used in motors, battery packs, BMS and energy storage systems test.

Battery charge / discharge function

Due to its unique bidirectional design, the FTB9000 series has a charge/discharge test function, and is suitable for charge/discharge tests of various batteries and energy storage devices.
