An intermediate product compared to the single axis controllers with integrated power stage are the new GeoBrick Drives of Delta Tau. They combine the full functionality of the Turbo PMAC2 controllers with a power stage for up to 8 axis into one housing. The input voltage ranges from 97 to 265Vac or 12 to 320Vdc at motor currents of 5 to 15Arms continuous.
The latest version is the low voltage amplifier GeoBrick-LV. The special thing about this amplifier is the 4-phase power bridge which can not only drive 3-phase servo motors but also 2-phase steppers and mixed configurations.
