The Control Techniques UNI3402 AC Drive is a powerful and versatile device designed to handle a variety of industrial applications with precision and efficiency. It is an integral part of the Unidrive range, offering an advanced solution for controlling motor speed and torque. With its ability to operate in multiple modes—Open Loop, Closed Loop Vector, Servo, and Regenerative (Regen)—this drive is suited for complex industrial automation processes, providing flexibility across various tasks.
The drive boasts a nominal power rating of 18.5 kW (30 hp), making it ideal for heavy-duty applications requiring precise motor control. Its robust construction and high performance are complemented by a compact design, allowing easy integration into existing setups without taking up excessive space. Furthermore, the drive operates efficiently across various frequencies, with a maximum continuous output current of 40 A at ambient temperatures of 40°C when running at 3 to 4.5 kHz. The current output decreases as the switching frequency increases, delivering 37 A at 6 kHz, 28 A at 9 kHz, and 23 A at 12 kHz. When operating at 50°C, the continuous output current adjusts accordingly, with maximum ratings of 34 A at 3 to 4.5 kHz and reduced outputs at higher frequencies, down to 17.9 A at 12 kHz.
One of the critical features of the UNI3402 AC Drive is its regenerative capability, which enables energy recovery in braking applications, reducing overall energy consumption and operational costs. This feature is handy in applications with frequent start-stop cycles or where precise deceleration is critical. The drive’s servo mode allows for high-precision motor control, making it suitable for tasks requiring accurate speed and position control.
The drive ensures optimal performance under various operating conditions with a typical input current of 32 A and a maximum continuous output current of 39 A. It also features a minimum resistance of 10 Ω, ensuring proper load balancing and stability during operation. Additionally, the instantaneous power rating of 60 kW means the drive can handle short bursts of higher power demand, offering superior handling during peak load conditions.
The Control Techniques UNI3402 is designed for longevity and durability, withstanding harsh industrial environments and fluctuating temperatures. Backed by a 2-year MRO Electric and Supply warranty, this drive provides peace of mind and reliable performance for years. Whether you're looking to streamline motor control in automation systems, improve energy efficiency, or enhance the precision of servo motor operations, the UNI3402 AC Drive is an excellent choice for diverse industrial applications.
What is the power rating of the UNI3402 AC Drive?
The UNI3402 AC Drive's nominal power rating is 18.5 kW (30 hp), making it ideal for demanding industrial applications requiring substantial motor control.
What operating modes are available for this drive?
The UNI3402 operates in four modes: Open Loop, Closed Loop Vector, Servo, and Regen. These modes offer flexibility for various applications, from standard motor control to regenerative braking and precise servo operations.
What is the maximum continuous output current at 40°C?
