The 2090-UCSR-A300 is a 300 Watt Active Shunt Regulator designed for use with specific Allen-Bradley drive products, particularly the Ultra3000, Ultra5000, and ULTRA 100 drives. This active shunt is used to monitor and regulate the dc bus voltage in systems that experience significant dc voltage regeneration from large inertial loads. The device is designed to prevent overvoltage faults by dissipating excess energy through a shunt circuitry.

Installation
The installation instructions for the 2090-UCSR-A300 are detailed in the publication 2090-IN002C-EN-P. The device should be placed in a metal enclosure to reduce electromagnetic interference (EMI) noise. For the ULTRA 100 drive, ferrites must be added to the ends of the twisted dc bus wires to comply with CE radiated emissions standards. The device should be mounted securely using metal screws and should have a minimum of 50 mm (2.0 in.) of clearance above and below the unit for air flow.
