The Allen-Bradley 2090-SR040-09 Ultra 3000 servo passive shunt resistor module is an external shunt module belonging to the Bulletin 2090 external shunt module family that is designed to provide a means of dissipating the excess regenerative energy that is developed by the Ultra 3000 servo drive DC Bus. The 2090-SR040-09 module is used only when the system load requires dissipative action that is beyond the capacity of the internal shunt resistor, and it remains in its passive state until it is activated by the servo drive. The 2090-SR040-09 module dissipates excess Bus voltage by passing the current through a resistor that dissipates the current as heat, and it is highly recommended to size the shunt properly to get the desired dissipative results.
The 2090-SR040-09 module is compatible with the Allen-Bradley Ultra 3000 230 to 460 Volts AC rated servo drives like the 2098-xxx-HV100 drive, and it has a resistance rating of 40 Ohms (in a 40 to 51 Ohms range). It has a continuous power rating of 900 Watts and a peak current rating of 20 Amps at 460 Volts AC. The 2090-SR040-09 module also has a peak power rating of 4 kilowatts at 230 Volts AC input voltage, and of 16 kilowatts at 460 Volts AC input voltage. The 2090-SR040-09 module is an externally mounted shunt module that can be installed on a cabinet by using the factory-supplied M6 (0.25 inches) bolts to fasten it to the subpanel. The 2090-SR040-09 module comes with a factory-installed 5-Amp, 700 Volts AC Bussman Ferrule fuse (the FWP-5A14F), which is field-replaceable. It has an operating ambient temperature range of 0 to 50 degrees Celsius, and it weighs approximately 3.6 kilograms (8.0 pounds).
