In below form there is the minimum resistance and power value to match different model. In actual use, the brake power value must be higher than that in the form, and the selection of the braking resistor power based on braking energy.
External brake resistor is a necessity for all VFDs. It can be selected according to brake energy and brake torque.
Input AC/DC reactor is a necessity for 160kw or higher power VFD; and is optional for power equal and under 132kw VFD.
K refers to brake frequency. K differs in industry and below can be taken as reference.
Micctech VFD power various from 5.5kw-160kw, has 15 styles in total and they share 6 sizes.
Brake unit is built-in for VFD power equal and under 22kw, and is not included(optional) for VFD over 22kw.
