Product Description
The Allen-Bradley 150-SC3NBD SMC-50 Smart Motor Controller is an intelligent, solid-state motor controller for three-phase induction motors, offering digital, microcomputer-powered starting. Its modular design simplifies installation and maintenance, and it features a DPI interface for network connectivity (DeviceNet, ControlNet, Ethernet, Remote I/O, Profibus). It accepts 200-480V AC input (50/60Hz) and is rated for 320A, suitable for 40-100HP motors with a rated current of 107-320A. The power circuit tolerates -15%/+10% voltage fluctuations (47-63Hz) and has 2200V dielectric withstand, providing DV/DT protection. The control circuit uses 100-240V AC, includes two 24V DC control inputs, two relay outputs, and has 1500V AC dielectric withstand. The 150-SC3NBD offers 9 start/stop modes, a front-panel keypad with LCD for programming, built-in protection, and dual-purpose LED indicators for status and diagnostics. It has two programmable auxiliary contacts (NO/NC) rated at 3A/1.5A (120/240V AC) configurable for various functions, and built-in electronic overload protection. It withstands 15G shock (11ms) and 1G vibration, operating up to 2000m altitude. CE, UL, and cUL-us certified, it weighs 47.6kg and ships in a 914.4mm x 1524.0mm x 355.6mm package. Its operating temperature range is -4 to 104F (open enclosure), and storage temperature range is -13 to 167F (5-95% non-condensing humidity).
Is Your Device Showing These Signs?
The Allen Bradley 150-SC3NBD SMC Flex Smart Motor Controller commonly experiences issues such as communication failures on the EtherNet/IP network, often stemming from incorrect IP address configurations or faulty network cabling. Overload faults are frequent, indicating excessive current draw due to motor issues or improper application parameters; verify motor FLA and adjust the overload settings accordingly. Short circuits can damage the SCRs and require replacement of the power module. Parameter corruption within the controller's memory necessitates a factory reset and reprogramming. Firmware upgrades are essential to resolve software bugs and improve performance.
