SP5401 Emerson Variable Frequency Inverter 0°C To 60°C Max 5.1 MA At 24V Dc
The SP5401 is a high-performance, fully digital servo drive from Emerson's Control Techniques portfolio, designed for advanced motion control applications. It serves as a key component in the Unidrive SP family, renowned for its flexibility and power. This all-in-one variable speed drive (VSD) combines a high-power switching stage, sophisticated digital signal processing, and a wide range of built-in control modes in a compact chassis. The SP5401 is engineered to deliver precise control for standard induction motors, permanent magnet synchronous motors, and induction servo motors, making it suitable for complex applications ranging from simple pumps to sophisticated, multi-axis machinery.
-
True All-in-One Flexibility: Supports multiple control modes (Open Loop Volts/Hz, Flux Vector Control, Induction Servo, Permanent Magnet Servo) within a single drive, allowing it to be adapted to a vast range of applications without hardware changes.
-
High-Performance Servo Control: Delivers exceptional dynamic response, precise positioning, and high torque accuracy when used in servo mode, meeting the demands of high-speed automation and machinery.
-
Advanced Programming & Connectivity: Features a powerful, user-programmable option module slot (for I/O expansion, Ethernet/IP, PROFIBUS, etc.) and the intuitive "Connect" software for easy commissioning, diagnostics, and custom application programming.
-
Regenerative Braking Capability: Includes a standard built-in Dynamic Brake Transistor (DBT) for handling overhauling loads, improving performance and reducing the need for external braking resistors in many cases.
-
Robust Design & Reliability: Engineered for demanding industrial environments with high immunity to electrical noise, a wide operating temperature range, and comprehensive protective features for the drive and motor.
-
Global Compliance & Safety: Designed to meet worldwide EMC, safety, and harmonic standards, facilitating deployment in global markets.
SP5401 Material & Primary Applications
-
Material: The drive is constructed with a robust sheet metal chassis (galvanized steel or aluminum) for EMI shielding and durability. The internal power stage uses high-efficiency Insulated-Gate Bipolar Transistors (IGBTs), mounted on a substantial aluminum heatsink. The main control board features multilayer PCB design with industrial-grade microprocessors, memory, and communication components.
-
Primary Applications: Due to its versatile nature, it is suitable for a wide array of applications, including:
-
Precision Conveying and Material Handling Systems
-
Packaging Machinery (fillers, wrappers, labelers)
-
Machine Tools (spindles, feeds)
-
Test and Simulation Equipment
-
Mixers, Extruders, and other Processing Machinery
-
High-performance Pumps and Fans with advanced control needs
