The Allen-Bradley 1398-SR3AF is an active external shunt module. This module is an external accessory that can be installed in any device in Allen-Bradley’s ULTRA 100™ series. The weight of Allen Bradley 1398-SR3AF is 3.34 lbs. This module can receive the shocks of up to 15g force, 11 ms half sine shock pulses. This shunt module can operate at an altitude of 1500 meters (5000 feet) without derating. This module requires sir flow clearances with a distance of 5 cm above or below the unit. Be sure there is enough ventilation to prevent overheating and fire. The humidity of the 1398-SR3AF module ranges between 5 and 90%. The ambient operating temperature of this active shunt module is between 0 and 40 °C. The power performance increases to around 5.5W if the ambient operating temperature decreases by 1 °C. If the ambient operating temperature increases by 1 °C, then the power performance decreases by about 5.5W as well. To connect the 1398-SR3AF shunt module to the drive, a shielded copper cable is required, with a high-temperature rating (75 °C, 600V), 4-2.5 mm2 (12 to 14 AWG).
The Allen-Bradley 1398-SR3AF works as a DC voltage monitor for a drive. If the DC voltage has reached the activation level, the module lowers the DC bus voltage then dissipates the energy as heat. The shunt module can release a very large amount of heat as time passes. Any material above the 1398-SR3AF module or enclosure should be protected by metal plates.
