Specifications Manufacturer: Danfoss Series: VLT 6000 HVAC Model: VLT6011 (VLT6011HT4C54STR3DLF10A00C0) Part Number: 178B0520 Power Rating: 7.5 kW / 10 HP Input Voltage: 3 x 380-460V AC, 50/60Hz Input Current: 15A / 14A Output Voltage: 3 x 0-Uin Output Current: 16A / 14A Output Frequency: 0-1000Hz Enclosure: IP54 / NEMA 12 Label Info T/C: VLT6011HT4C54STR3DLF10A00C0 C/N: 178B0520 S/N: 011539G115 Application Ideal for controlling motors in HVAC systems, including centrifugal pumps, fans, blowers, and compressors, to improve energy efficiency and process control. Country of Origin Made in Denmark CO2 Impact By purchasing this pre-owned drive, you are helping to avoid the emission of approximately 280 kg of CO2, which would have been generated during the production of a new unit. This is comparable to the emissions from driving a car for over 1400 kilometers. Availability This is an obsolete item, but it is available from our stock as a reliable spare part for existing installations. Order now from profideals for expert support and fast delivery. FAQ Can this VLT 6000 be used with a standard induction motor, or does it require a special vector-duty motor?The VLT 6000 series is designed to work excellently with standard asynchronous (induction) motors. It operates on a V/Hz (Voltage/Frequency) control principle, which is ideal for common HVAC applications like pumps and fans without requiring a special motor. What is the typical lifespan of the internal DC-link capacitors and the cooling fan on this model?For the VLT 6000 series, the electrolytic DC-link capacitors generally have a design life of 8-10 years under normal operating conditions. The cooling fan is also a component with a finite lifespan, typically around 40,000 to 60,000 operating hours. It’s recommended to check these components during preventive maintenance, especially on older units. Is the control panel (LCP) removable on the VLT 6000, and can settings be copied from one drive to another?Yes, the Local Control Panel (LCP) is removable. It can be mounted remotely using an optional kit. The LCP has a copy function that allows you to upload the entire parameter set from one drive and download it to another identical drive, which is extremely useful for commissioning multiple units. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
