Control Techniques UNI2403

The UNI2403 Unidrive is an advanced and efficient AC Drive manufactured by Control Techniques. It offers various control options with both open and closed-loop configurations. The drive is equipped with a user-friendly keypad for easy operation. The drive supports induction and servo motors, enhancing its versatility and adaptability. Key features of this drive module include its high-power rating, extensive control options, robust braking capabilities, and reliability in demanding environments.

Technical Features:

The UNI2403 Unidrive has an instantaneous power rating of 20 KW, and the power rating for constant torque is 7.5 KW (10 hp). Its compact design measures a depth of 200 mm, a width of 190 mm, and a height of 335 mm.

This drive supports maximum motor cable lengths of 330 meters for a 400 V nominal AC supply voltage. For braking, the drive offers a minimum resistance of 30 ohms. The minimum resistance of this drive is 30 ohms for the braking resistor at 40°C.

The typical input current of Control Techniques UNI2403 is 21 A, while the maximum continuous input current is 25 A. The cable size for this high-current drive is 4 AWG (American Wire Gauge 10).

Mechanical Installation:

The mechanical installation of the UNI2403 drive module consists of several key components that ensure proper setup and operation. This drive uses specific RFI (Radio Frequency Interference) filters like the FS5113-25-29 for optimal performance.

These filters suppress electromagnetic interference and ensure compliance with EMC (Electromagnetic Compatibility) standards. RFI filters can assist in preventing electromagnetic interference from producing hazardous situations like faulty safety systems or uncontrolled device behavior.

Flexibility of Five Modes:

The UNI2403 drive module offers five different modes, enhancing its adaptability and ease of use. The Open Loop V/F Control model is used with standard AC induction motors. This mode is suitable for precise speed control and is often utilized in fan and pump applications.

The Open Loop Space Vector Control mode is an advanced version of the V/F control. This mode suits applications requiring smoother operation and high dynamic performance.

Closed Loop Flux Vector Control mode is engineered for applications that require precise speed and torque control. This makes it ideal for high-performance applications such as conveyors, hoists, and cranes. Servo mode is perfect for high-precision applications like robotics and CNC machines.

Regeneration mode enables the drive to feed energy back into the power supply during braking. It is an energy-efficient application, including elevators, cranes, and load systems.
