The Emerson Unidrive SP AC Drive is a versatile product from the Unidrive SP series, designed for 3-phase 380-480 VAC input. It offers dual power ratings: 7.5kW (10hp) Heavy Duty and 11kW (15hp) Normal Duty. Corresponding continuous output currents are 16.5A (HD) and 21A (ND). This Size 2 drive supports multiple control modes including Open/Closed Loop Vector, Servo, V/Hz, and Rotor Flux Control (RFC). It features an IP20 rating, onboard EMC filter, dynamic braking control, universal encoder interface, and 3 option module slots for enhanced connectivity. It incorporates Safe Torque Off (STO, SIL 3) for functional safety. A keypad (SM-Keypad) is typically required for operation and sold separately. Note: This product is discontinued/in phase-out by the manufacturer.

The Control Techniques Unidrive SP3403 AC Drive is a high-performance solution designed for demanding industrial applications. As part of the renowned Unidrive SP series, this modular drive offers unparalleled flexibility and precision. It operates in five distinct modes: Servo for high-dynamic precision control, Open-loop vector for standard induction motors, Closed-loop vector for precise control with motor feedback, V/Hz (scalar) for simple motor speed control, and Regen for regenerating energy back to the power source.The SP3403 model, identified by its Frame Size 3, is designed for 380-480V AC three-phase input and typically supports a power rating of 4 kW / 5 HP in normal duty applications. Its modularity is a standout feature, with three option module slots available for adding advanced functionalities such as feedback devices (encoders, resolvers), I/O expansion, and various industrial communication protocols including PROFIBUS and EtherNet/IP.This drive is a legacy product, having been succeeded by the modern Unidrive M series, specifically the M700 series from Nidec Control Techniques. Despite being a legacy product, the Unidrive SP3403 remains a reliable and versatile choice for complex industrial environments.
