Braking unit FWI-BU3 series

Braking unit also some times referred as Dynamic braking unit may refer to: DC Injection braking unit, an electrical braking device for ac motors Regenerative braking unit, regenerative braking systems used in traction motors Electromagnetic brake, Devices using electromagnetic forces to mechanically brake Braking chopper, an electronic switch used to dissipate high voltage in intermediate bus of VFD into resistors The function of the VTdrive HBU braking unit is to divert into a braking resistor the regenerative energy produced in the process of decelerating the motor, converting that energy into heat. Regenerative energy flows from the motor into the inverter DC Bus, manifested as increased bus voltage. The advantage gained using the HBU is improved braking performance and shorter deceleration time of the load. Features: 1.For all brands VFD; 2.200V/380V/440V/480V; 3.It could be paralleled connected, no capacity limited; 4.Allowable for the occasion with electricity fluctuation; 5.Special design, the ordinary resistor could be used so no need to use senseless resistor. Resistor box could be specially ordered; 6.Ensure the brake IGBT in saturation; 7.Protection: short-circuit, low voltage, over voltage, fast fuse, over heated; 8.Automatic track during the whole process; 9.Noise filtrated within all frequency range, no disturbance to other equipments.
