VLT 3006

The Danfoss VLT 3006 Variable Speed Drive, part of the VLT 3000 Variable Speed Drives series from Danfoss, delivers robust performance for a wide range of industrial automation applications. This drive provides a continuous 7.6 kVA output power rating and supports a nominal output current of 19 A, with a typical shaft output of 4 kW in CT mode. It operates on a three-phase supply of 3 x 200/220/230 V ±10%, and offers a programmable output frequency range from 0 to 500 Hz for precise motor control. Enclosed to an IP20/IP54 protection class, the VLT 3006 combines durability in harsh environments with the flexibility of programmable logic and adjustable ramp profiles to meet varying process demands.

Detailed electrical and mechanical specifications deliver a comprehensive performance envelope for the VLT 3006. The drive accommodates a maximum input current in quadratic load conditions of 23.1 A and supports a maximum cable cross-section of 16 mm2 for power connections. Ramp times are user-configurable from 0.1 to 3600 s, enabling both rapid start-stop sequences and gentler acceleration curves. Thermal protection is managed by an integrated thermistor conforming to DIN 44081, while the drive’s short-circuit, earth-fault, and electronic thermal motor (ETR) protection features guard against overload and ground faults. In addition, the unit meets stringent EMC emission requirements, complying with EN 55011 and EN 55014 standards for industrial environments.

Operational performance is optimized across varied ambient conditions. In CT rating, the VLT 3006 continuously operates between –10 to +45 °C, while in VT rating a slightly reduced range of –10 to +40 °C is maintained at full load. For transport and storage, the unit withstands temperatures from –25 °C to +65/70 °C, and operates reliably in up to 95% relative non-condensing humidity. These environmental tolerances ensure long-term stability in factories, machine rooms, and outdoor enclosures with fluctuating temperatures and moisture levels. The on-board process logic and overload protection mechanisms support uninterrupted operation and reduce downtime in demanding industrial processes.

System integration is streamlined through standard control interfaces and compatibility with common fieldbus protocols, facilitating deployment in existing Danfoss automation architectures. The compact footprint and modular design allow easy retrofitting into panel boards or standalone installations, making it ideal for medium-duty pumps, fans, conveyors, and chillers. With its combination of precise frequency control, comprehensive protection features, and broad environmental tolerances, the Danfoss VLT 3006 drive meets the needs of manufacturing, HVAC, water treatment, and material handling sectors seeking reliable and efficient motor control solutions.
