To rapidly brake high inertia loads, Alstom has introduced a high voltage dynamic brake unit, the GDB400-4601. The unit is fully compatible with Alstom’s latest inverter – the Alspa MV3000 – as well as GD3000 inverters.
A major feature of the unit is its ability to accommodate high voltage mains supplies of 525V to 690V. These correspond to inverter DC link voltages of 830V and 1125V respectively.
Capable of switching 400A at a 25% duty cycle, the units are suitable for use with high inertia loads such as hoists and large fans.
