The UNI4402, a pinnacle of AC Drive technology, is defined by its impressive technical specifications:
What is the nominal power rating of the UNI4402 AC Drive?
The UNI4402 is rated for 55 kW or 100 horsepower under nominal conditions, making it suitable for high-demand industrial applications.
What are the supported operating modes of the UNI4402?
This AC drive supports Open Loop, Closed Loop Vector, Servo, and Regenerative (Regen) modes, offering flexibility for a wide range of motion control applications.
How does ambient temperature affect the output current capacity of the UNI4402?
At 40°C ambient temperature, the drive supports higher output currents, up to 124 A at 3 kHz. However, due to thermal limitations, at 50°C, the maximum output current decreases to 105 A at 3 kHz.
What is the maximum continuous output current supported by this drive?
The UNI4402 can deliver up to 114 A of continuous output current, depending on the switching frequency and cooling conditions.
How does switching frequency impact the output current of the UNI4402?
Higher switching frequencies reduce the drive's continuous current capacity. For example, at 9 kHz, the maximum output current drops to 70 A at 40°C and 60 A at 50°C.
What is the typical input current required for this drive to operate efficiently?
The typical input current for the UNI4402 is 91 A, which should be considered when sizing circuit protection and power supplies.
What is the minimum resistance the UNI4402 can tolerate on its braking resistor circuit?
The drive requires a minimum resistance of 5 ohms to ensure safe and efficient regenerative braking performance.
What is the instantaneous power rating of the UNI4402, and what does it imply?
The drive's instantaneous power rating is 120 kW, which indicates its ability to handle high peak loads or rapid acceleration demands for short durations.
Can the UNI4402 be used in regenerative applications?
Yes, the drive supports regenerative mode, meaning it can recover braking energy and feed it back to the power system, improving overall energy efficiency.
Is the drive suitable for servo applications?
Absolutely. With its support for servo control mode and precise torque and speed regulation, the UNI4402 is ideal for servo-based motion systems.
