Product introduction
Product Profile
VTF900 series is a modular design, with the characteristics of compact structure, easy installation and debugging, suitable for any brand of frequency converter or inverter, energy feedback and rectifier feedback can be exchanged at any field application; The working principle is to return the regenerative energy generated in the process of motor speed regulation to the power grid; The energy loss caused by the resistance heating of the conventional energy consumption type brake unit is avoided, so as to achieve the objective energy-saving effect.
Product Features
● By using phase-locked algorithm and instantaneous reactive power algorithm,the harmonic pollution can be reduced effectively,and the unit power factor can be reached when the operation conditions are close to stability.
● Whole-process noise filtering - will not pollute the power grid and interfere with other equipment, with its own reactor and filter, can be directly connected to the power grid.
● Two operation modes: one is manual operation,the other is automatic operation;
● The software design accurately calculates the power feed and power consumption;
● Working mode: rectifier feedback , inverter feedback , arbitrary switching;
Applications
Widely used in elevators, port machinery, tower cranes, blast furnace charging cars, mine charging cars, oil field pumping units, lifting load situations, and renewable energy power generation situations.
