Product Details

MFC780 energy feedback inverter is special designed for three-phase asynchronous motor , allows power supply bidirectional flow (the motor can work on two kinds of state of electric and regeneration ).predispose energy feedback unit,  double DSP control, and fully ensure the high performance and reliability of the energy feedback unit. Compared with a traditional external energy feedback unit, performance greatly improved and smaller volume. with four quadrant operation functions  which can meet speed requirements of all kinds of potential energy load such as crane, elevator, oil beam pumping unit , can feedback motor renewable energy back to the grid, achieve the goal of saving maximum energy.  it also reduces the harmonic pollution to power network, the power factor is close to 1, and is a real sense of "green" inverter. It can customize explosion-proof type according to user requirements.

Product feature

Won’t produce commutation gap, no commutation failure

Harmonics can be ignored

For grid strong adaptability for grid, even grid has instantaneous fluctuation, still can maintain the stability of the bus voltage

Inverter has good dynamic response, faster response to load fluctuations

Four quadrant operation ability, can smooth transfer between electric and power status, can feedback energy 100%

DC bus voltage stable and controllable, and has the ability to improve the voltage

Power factor control, usually can be set to 1.Don't need compensation device

Applications:

Widely used in the large inertia loads, raise load and fast brake of the variable frequency speed regulation system, more than 97% of renewable electricity energy which generate in the braking process back to the grid.
