Rockwell / Allen-Bradley 2090-UCSR-A300 / 1398-SR3AF 300 W Active Shunt Modules
- Smooth Braking of Large Inertial Loads
- Monitors the DC Bus Voltage
- Dissipates the Energy as Heat
The Rockwell / Allen-Bradley 2090-UCSR-A300 / 1398-SR3AF 300 W Active Shunt Modules are used in systems that see significant dc voltage regeneration from large inertial load applications. The Allen-Bradley Ultra3000, Ultra5000, and ULTRA 100 drives do not have internal shunt circuitry to dissipate excess energy, resulting in overvoltage faults. For the smooth braking of large inertial loads, the use of a shunt regulator is recommended. The active shunt monitors the dc bus voltage of the drive. If the voltage reaches activation level, the shunt drops the dc bus voltage and dissipates the energy as heat.
