Product introduction and application of DC Braking Module
Product Introduction
The braking unit component is installed on the DC side of the frequency converter, and the regenerated electric energy is consumed on the power resistor to achieve braking. The regenerative energy is consumed on the resistor and converted into heat energy through a dedicated energy consumption braking control circuit.
Product Application
It is mainly used in occasions where the inverter driving system requires sharp deceleration, braking, positioning, etc. When the frequency converter is decelerating, due to the large inertia of the drag system, the motor is in the power generation state at this time, and the mechanical energy is quickly fed back to the DC bus, causing the DC bus voltage to rise rapidly, thus endangering the safety of the frequency converter. Therefore, the feedback energy must be Consume it quickly and keep the DC bus voltage below a certain safe range, otherwise the inverter will have overvoltage protection or malfunction. Generally, this braking unit can be used in situations where the inertia is large, or where rapid deceleration or braking is required. For example: centrifuge elevators, cranes, wire drawing machines, port machinery, etc. can be used.
