Control resistor unit / braking
ShenZhen INVT Electric Co., Ltd.
The RBU Series has a regenerative braking unit that regenerates the energy back to the grid. It has a breaking resistance of rated current of 150% in 30s, 100 % in 1 min and 80% always. To control, the current control must have a phase angle of 120° and to operate, use the external terminal (Keypad). The protection level is IP20 preventing over-current, over-voltage and over-temperature.
