Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 2090-UCSR-A300 is an external active shunt regulator module from Allen-Bradley's Ultra3000 drive accessory line. It mounts to Ultra3000 servo drives (e.g., 2098-DSD-005, -010, -020) to provide supplemental DC bus shunt regulation when the drive's internal shunt is insufficient. It handles energy dissipation during regenerative braking and overvoltage events. Although the product was discontinued as of December 31, 2022, the 2090-UCSR-A300 remains relevant for legacy system maintenance and retrofit planning.
Best Suited For
- Ultra3000 servo drive systems (2098-DSD-005/010/020)
- Applications with high regenerative energy requiring external shunt support
- Retrofits or maintenance of legacy Kinetix Ultra3000 installations
- When internal drive shunt capacity is exceeded
