VLT 5003
The Danfoss VLT 5003 frequency converter, part of the VLT 5000 Frequency Converters series by Danfoss, is engineered to deliver precise motor control and superior energy efficiency in industrial automation. With a nominal motor power of 1.5 kW and an input voltage range of 3 x 380-500 V AC, this unit ensures stable operation across common plant voltages. It provides an impressive output frequency range of 0-1000 Hz, allowing fine-tuned speed regulation for pumps, fans, conveyors and other motor-driven applications. Its primary function is to optimize motor performance, reduce energy consumption and maintain consistent torque under variable loads.
The VLT 5003 stands out through its robust technical specifications. It handles an apparent power of 3.1-2.9 kVA while supporting an input current between 3.8-3.4 A. The converter’s inductance of 1.934 mH (1.050 mH at 200–240 V) contributes to reduced harmonics and smoother current flow. Output current ranges from 4.1-3.4 A, ensuring reliable power delivery to the motor. Built on the VLT 5000 platform (Product Code 175Z0043), it leverages advanced modulation techniques to maintain accurate voltage output (3 x 0-Uin V AC) and responsive dynamic performance.
Designed for industrial settings, the VLT 5003 offers high compatibility with standard three-phase networks and can seamlessly integrate into existing automation architectures. Its efficient topology minimizes heat generation, extending service intervals and lowering maintenance costs. Although it carries IP20 protection, the converter performs reliably in controlled environments, ensuring component longevity. By providing consistent speed and torque control with minimal energy losses, the VLT 5003 enhances process stability and reduces operational expenses. In demanding industrial applications, this frequency converter delivers precise control, increased uptime and significant energy savings.
