Frequency converters - NAFTECH HVAC ENGINEERING

Variable frequency drives are widely used on pumps, compressors and large plant ventilation systems to adjust flow or pressure to actual demand. Significant energy savings can be achieved with an installation equipped with a frequency converter; They control the frequency of the electrical power supplied to the pumps or fans. Find the ideal drive for your motor control or power conversion application, along with options and accessories.

The ATV930 variable speed drive of 3kW and 240V Tri, IP21

The ATV930 3kW, 240V Tri, IP21 inverter meets the needs of motor control in industrial processes and infrastructures requiring advanced control and connectivity. EMC filter (C2). This drive, with braking unit, is designed to be mounted in a vertical position (+/- 10°) on a wall. With its connectivity, this product can handle advanced process functions (master-slave, brake control) in the following market segments: oil and gas, mining, minerals and metals, water for food and beverage and wastewater. It has been designed to withstand the harshest industrial environments such as the electro-intensive process segments: Steel, Oil, Material Handling, Material Extraction, ... The ATV930 drives and controls the drive train according to mechanical parameters derived from the motor model for optimal torque control and command even at zero speed for Rewinder/Unwinder applications. The product's advanced connectivity, including EtherNet/IP and Modbus TCP, enables deep integration into automation architectures. The performance of the ATV930 range meets most demanding international standards and approvals: CE, ATEX, UL 508C, UL61800-5-1, CSA 22.2 N274, NOM, GOST, EAC, CTICK, RCM, KC, SIL, Class 3C3 and 3S2 to IEC 60721-3-3. This product is Green Premium certified, the eco-label that promises sustainable and environmentally friendly performance. It is also EU ROHS compliant. Combining ATV930 services with SE automation control systems such as EcoStruxure provides a high performance, fully automated, cost effective motor control solution. External accessories and options can be combined with Altivar Machine ATV930 drives. The availability of these depends on the drive rating: braking resistor, line and motor choke, compliance kit.
