7.8Amp Driver Pack
The external driver pack is based around the 7.8Amp module from Arc Euro Trade. This provides sufficient drive for the 680Ncm motor and runs directly off the output of the DivisionMaster.

The Enable output is active when the LED is lit on DivisionMaster, otherwise the the motor is disabled. If it is necessary to maintain power to the motor for holding purposes, then use pin 7 rather than pin 8, and the motor will only be switched off when DivisionMaster is switched off.
Power supply is a transformer and bridge rectifier arrangement providing around 70V to the driver module. This leaves a large margin of headroom to the 90V maximum.
