Brake control unit (chopper) for Universal Motors UMP1 AC Frequency Inverter Drive.90-110kW units
Fits onto the front/top of the drive to provide braking to an external resistor of a minimum of 4.4 Ohms.
100% of the adaptation braking resistor of the braking torque(Ω) 90kW and 110kW rated = 5.4 and 4.5 Ω respectively
Dissipated power of the braking resistor(kW) 90kW rating, (10%, 50% & 80% braking respectively) 14/68/108 kW
Dissipated power of the braking resistor(kW) 110kW rating, (10%, 50% & 80% braking respectively) 17/83/132 kW
Connections +/- DC Bus and +/PB resistor terminals, PE
Control PCB: External faul plus Fault relay changeover relay and Master Slave connections
DC Bus threshold Dip switch setable between 340V and 780V DC = Slave mode
