Danfoss Water & Wastewater Announces New Features For Variable Frequency Drives

Compact, Versatile VLT®2800 Series Variable Frequency Drives Offer New Features for Enhanced Operation in Low Power Applications
Milwaukee, WI Danfoss Water & Wastewater announces their popular VLT®2800 Series Variable Frequency Drives are now available with enhanced sleep functionality, run-dry detection and pipe fill mode as standard. These new features promise to significantly improve pump operation and protection, while increasing overall energy efficiency.
When using pumps with flat pump curves or when suction pressure varies, enhanced sleep functionality provides optimum control for shutting down the pump at low flows. Run-dry detection protects a pump against damage should the operation run dry, and pipe fill mode prevents water hammer.
These multipurpose drives are engineered specifically for low-power applications and are available in 0.5 – 2 HP, 200-240V, 1 or 3-phase; 3 – 5 HP, 200-240V, 3-phase; and 0.75 – 25 HP, 380-480V configurations. They offer side-by-side mounting in any direction and include a built-in PID controller, RFI filter, DC coils and cold plate technology as standard.
Bookstyle drives up to 10 HP are available with IP20 protection as standard and NEMA 1 optional, and drives in the 15-25 HP range come standard with a NEMA 1 enclosure. An integrated RS485 interface is standard, with integrated Devicenet or PROFIBUS as available options.
