Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 2090-SR120-09 is a passive shunt resistor module in the Allen-Bradley 2090 series designed for use with Ultra3000 (High-Voltage) servo drives. With a resistance of 120 Ω, it provides external dynamic braking when the internal drive shunt is insufficient. It connects externally to Ultra3000 HV03X and HV05X drives, enabling energy dissipation under regenerative load conditions. The 2090-SR120-09 is part of the Ultra3000 platform and supports reliable drive operation in high-energy deceleration scenarios. 2090-SR120-09 is discontinued by the manufacturer.
Best Suited For
- Ultra3000 HV030/HV050 servo drive systems
- Applications with high regenerative energy demands
- External dynamic braking needs
- Replacement for drives lacking sufficient internal shunt capacity
