Control Techniques UNI2403 Overview

Control Techniques UNI2403 Size 2 Drive: A Technical Description


The Control Techniques UNI2403 is a state-of-the-art AC drive from a renowned manufacturer. Known for its flexibility in operation and efficiency, the drive offers several modes that cater to different application needs. This technical description delves deeper into its specifications and features.

General Overview:

  • Part Number: UNI2403
  • Manufacturer: Control Techniques
  • Type: AC Drives
  • Warranty: 2 years

Operating Modes:

The UNI2403 offers four distinct operating modes, making it versatile for varied applications:

  1. Open Loop: This is the most straightforward mode, where the drive operates without continuous feedback.
  2. Closed Loop Vector: In this mode, the drive continuously adjusts its operation based on the feedback received, ensuring better accuracy.
  3. Servo: This mode is for precise control typically in robotics or CNC machines.
  4. Regen: Allows the drive to regenerate energy back into the system, typically during braking or when motor speed exceeds the drive speed.

Nominal Ratings:

  • Power in kW: 11 kW
  • Power in HP: 15 HP

This defines the standard operational power limits of the drive, indicating the power it can handle under normal conditions.

Output Current at Different Frequencies (40°C Ambient):

Frequency operation and the corresponding maximum continuous output current values at 40°C are:

  • 3kHz: 25A
  • 4.5kHz: 21.7A
  • 6kHz: 18.2A
  • 9kHz: 14.2A
  • 12kHz: 11.7A

Output Current at Different Frequencies (50°C Ambient):

At a slightly higher ambient temperature of 50°C, the drive's maximum continuous output current ratings are:

  • 3kHz: 20A
  • 4.5kHz: 17.3A
  • 6kHz: 14.7A
  • 9kHz: 11.6A
  • 12kHz: 9.7A

This indicates the drive's robustness in different temperature environments. It also emphasizes the importance of adequate cooling and ventilation when the drive is operated in warmer settings.

Input and Output Current Ratings:

  • Typical Input Current: 21A
  • Max Continuous Output Current: 25A

This describes the average current the drive will draw from its power source and the maximum continuous output current it can supply to the motor.

Minimum Resistance:

The UNI2403 has a specified minimum resistance of 30 ohms (Ω). This parameter is essential when designing protection and control circuits, ensuring the drive's safety and the connected motor's longevity.

Instantaneous Power Rating:

The drive boasts an impressive instantaneous power rating of 20 kW. This signifies the peak power the drive can handle for brief moments, accommodating transient spikes in power demand without damage or degradation in performance.

FAQs about Control Techniques UNI2403 Size 2 Drive

1. What types of applications are best suited for the UNI2403 drive?

Answer: The UNI2403 is versatile and can be employed across a range of applications. Its multiple operating modes, like Open Loop, Closed Loop Vector, and Servo, make it ideal for manufacturing processes, robotics, CNC machines, conveyor systems, and other machinery requiring precise motor control.

2. How does the drive ensure optimal performance in varying ambient temperatures?

Answer: The UNI2403 is designed to offer different maximum continuous output current ratings at 40°C and 50°C ambient temperatures. It emphasizes the need for adequate cooling and ventilation when operated in warmer settings. Ensure that the installation environment provides proper cooling to maximize the drive's longevity and performance.

3. Is there a safety feature to protect against excessive power demands?

Answer: Yes, the drive has an impressive instantaneous power rating of 20 kW, allowing it to handle brief moments of transient spikes in power demand without damage. This ensures that the drive remains protected even during sudden changes in load or other operational scenarios that might pose power spikes.

4. How does the 'Regen' mode benefit the overall system?

Answer: The 'Regen' mode allows the drive to regenerate energy back into the system. This is particularly useful during braking or when the motor speed exceeds the drive speed. Not only does this help in energy conservation, but it also contributes to efficient braking and improved overall system efficiency.
