About the Product
Allen-Bradley SMC-Flex 150-N4A Smart Motor Controller & Soft Starter
Core Technical Specifications
- Brand & Model: This is the 150-N4A model from Allen-Bradley's established SMC-Flex product family.
- Power Rating: The controller operates at a rated voltage of 480V to 690V AC.
- Operating Frequency: It functions on standard 50/60 Hz power systems.
- Key Component: The unit utilizes six silicon-controlled rectifiers (SCRs) — two per phase — for precise torque and current management.
- Integrated Bypass: The module includes an integrated bypass for current ranges from 108A to 480A, improving efficiency.
- Compact Design: The controller is lightweight with a net weight of approximately 1.36 kg (3.0 lbs).
Control Features & Functionality
- Motor Control: The 150-N4A controls motor torque during start, run, and stop cycles by managing the conduction period of the SCRs.
- Advanced Protection: It includes comprehensive power monitoring and motor protection features to maximize operational reliability and prevent damage.
- Scalable Connectivity: Three dedicated connection ports allow for network communication, additional I/O, or configuration devices.
- Configuration Options: You can configure the system via a multilingual 20-HIM-A6 keypad with LCD, network tools, or PC software.
- Resistive Load Control: The controller can directly manage connected resistor loads using phase-angle control, adjusting output voltage based on a programmable reference.
User Interface & Diagnostics
- Status Indicator: A front-panel multicolored LED provides clear controller status and diagnostic information at a glance.
- Manual Control: A Hold-to-Test/Push-to-Reset button allows for manual reset after a fault and can initiate a test cycle.
- Emergency Run Feature: If configured for Emergency Run and activated, this feature disables all system faults to prevent a full shutdown during critical operations.
- Flexible Reference Source: The control reference for phase-angle adjustment is fully programmable and highly flexible, adapting to various application needs.
Packaging & Shipping
- Package Contents: Includes one (1) Allen-Bradley 150-N4A Smart Motor Controller module and accompanying documentation.
- Shipping: We ship all orders promptly via reliable global carriers like FedEx, UPS, or DHL.
