The DBU100H series dynamic braking unit is the high-performance, heavy-duty braking unit promoted by INVT. It allows braking at rated current to meet the requirements of the application in situations of deceleration of masses of high inertia, and/or in case of rapid stops.
In an inverter system when the motor brakes, kinematic energy is converted into electrical energy and, in case of high inertia or fast deceleration, the DC bus voltage increases. The braking unit may consume excess regenerative electrical energy to ensure normal operation of the system, which may otherwise go into overvoltage protection on the bus.
The braking unit can therefore be advantageously used on lifts, textile machines, paper machines, centrifuges, washing machines, drawing machines, winders, cranes and lifting systems.
On the GD20-EU and GD350 series inverters, the braking unit is already integrated up to a power of 37kW.
