About the Series

Product Family & Positioning

SMC Flex is part of Smart Motor Controller (SMC™) family. It is a modular, microprocessor‑based soft starter designed to control and protect three‑phase induction motors.

Key Features

Modular Design: Removable control module, power modules, and fan assembly for easier installation, maintenance, and service.
Advanced Intelligence: Built‑in LCD and keypad for local setup; also configurable via PC software.
Integrated Bypass: Once the motor reaches full speed, internal bypass contacts bridge the SCRs to reduce heat and save space.
Multiple Control Modes:
– Soft Start, Current Limit, Kickstart, Dual Ramp Start, Full Voltage Start
– Pump Control (for fluid surge reduction)
– Preset Slow Speed (for positioning/alignment)
– Smart Motor Braking (SMB™), Accu‑Stop™, Slow Speed with Braking
– Linear Speed Acceleration (requires tachometer)
Communications Flexibility: Built‑in DPI ports for connecting Human Interface Modules (HIMs) and communication adapters (DeviceNet™, EtherNet/IP™, PROFIBUS, Modbus/TCP, etc.).
Comprehensive Diagnostics & Metering: Real‑time monitoring of current, voltage, power, energy, power factor, motor thermal capacity, etc.
Protection & Alarms: Includes overload, undervoltage, overvoltage, phase unbalance, jam, stall, ground fault, and more.

Accessories & Options

Protective Modules: For line or load side protection (480V or 600V).
Terminal Lug Kits: Required for controllers rated 108 A and above.
Human Interface Modules (HIMs): Hand‑held or door‑mounted LCD keypads.
Communication Modules: Adapters for various industrial networks.
Upgrade Kits: Allow conversion from SMC Flex to SMC‑50 controllers (with bypass).
