The Control Techniques UNI1404 is a compact, high-efficiency AC drive for precision motor control in demanding industrial applications. Part of the advanced Unidrive series, the UNI1404 offers exceptional flexibility, supporting multiple operating modes, including Open Loop, Closed Loop Vector, Servo, and Regenerative (Regen) control. This versatility makes it a powerful all-in-one drive solution for manufacturers, system integrators, and OEMs looking to maximize performance and adaptability.
Rated at 2.2 kW (3 HP), the UNI1404 delivers reliable power and consistent performance across various automation tasks. Whether driving standard induction motors or dynamic servo systems, this drive ensures stable torque and accurate speed regulation. Its design allows it to operate efficiently in fluctuating loads and thermal conditions.
One of the key strengths of the UNI1404 is its intelligent thermal design. At 40°C ambient temperature, the drive provides a maximum continuous output current of 5.6 A across multiple switching frequencies—3, 4.5, 6, and 9 kHz. At 12 kHz, the current is rated at 4.5 A, ensuring lower heat generation without sacrificing performance. It performs with reduced ratings for higher ambient conditions up to 50°C, such as 5.1 A at 6 kHz, 4 A at 9 kHz, and 3.3 A at 12 kHz, enabling reliable operation in warmer environments.
With a typical input current of 8.2 A and a maximum continuous output current of 8.6 A, the UNI1404 is well-suited for applications demanding fast acceleration, deceleration, and torque precision. Its instantaneous power rating of 15 kW allows it to handle peak load conditions smoothly. The minimum resistance of 40 ohms ensures safe and controlled braking and regeneration capabilities, making it ideal for dynamic stopping or power recovery applications.
This drive is designed to simplify commissioning and integration. Users can seamlessly transition between control modes depending on the application's requirements, from basic speed control to highly responsive servo applications. The robust construction and high reliability make it suitable for material handling, packaging, machine tools, and automated production systems.
Backed by a 2-year warranty from MRO Electric and Supply, the Control Techniques UNI1404 AC drive is available immediately with free shipping. It ensures minimal downtime and fast implementation for your automation needs.
