Control Techniques UNI3401

Control Techniques UNI3401 AC Drive Overview

The Control Techniques UNI3401 is a versatile AC Drive that provides highly efficient motor control in various industrial applications. Its advanced capabilities support operating modes such as open loop, closed loop vector, servo, and regenerative braking (regen), making it suitable for a wide range of systems requiring different levels of precision and performance. With power, flexibility, and reliability, the UNI3401 is an ideal solution for industries looking to optimize motor performance.

Power Ratings and Performance

The UNI3401 drive is built to handle substantial power loads, making it a reliable choice for demanding environments. It features a nominal power rating of 15 kW (25 hp), which ensures it can easily handle medium-sized industrial motors. Regarding current output, the drive can continuously deliver 34 amps at ambient temperatures up to 40°C when operating at switching frequencies of 3kHz, 4.5kHz, and 6kHz. For higher frequencies of 9kHz and 12kHz, the output current adjusts to 28 amps and 23 amps, respectively.

At an ambient temperature of 50°C, the current output values shift slightly. For switching frequencies of 3kHz and 4.5kHz, the drive maintains a continuous output current of 34 amps, but at 6kHz, it reduces to 28 amps, and at 9kHz and 12kHz, the current drops further to 21 amps and 17.9 amps. This ability to dynamically adjust the current depending on the temperature and frequency helps prevent overheating, contributing to the system's longevity.

Input and Output Characteristics

The Control Techniques UNI3401 has a typical input current rating of 32 amps, which ensures stable and efficient operation. Its maximum continuous output current is rated at 39 amps, allowing excellent performance under constant load conditions. Additionally, the drive is designed to handle instantaneous power ratings of up to 60 kW, making it capable of managing short bursts of high energy demand without compromising performance.

The drive also incorporates a minimum resistance requirement of 10 ohms, ensuring it operates efficiently with minimal energy loss during motor control. This characteristic further enhances the drive's performance in various operating environments.

Temperature and Cooling

The UNI3401 drive is designed to operate effectively in diverse temperatures, from 40°C to 50°C. The internal cooling system adjusts based on the switching frequency and current demands to ensure optimal temperature management. Its flexibility in adapting to ambient temperatures without sacrificing performance ensures it can withstand continuous operation in harsh industrial settings.

Applications and Flexibility

One of the standout features of the Control Techniques UNI3401 is its flexibility in terms of operating modes. The open loop mode provides essential control for applications that don’t require high levels of precision. In contrast, the closed loop vector mode offers more accurate control for tasks requiring precise motor speed and torque regulation. The servo mode enables quick and accurate positioning, ideal for robotics or automated machinery. The regen mode also allows energy recovery during braking, contributing to energy efficiency and reducing operational costs.

The Control Techniques UNI3401 is a highly adaptable and powerful AC Drive suitable for various industrial applications. Its advanced control modes, robust power ratings, and efficient thermal management make it a reliable choice for optimizing motor performance across multiple environments.
