Product Release: Danfoss VLT Drives


3/12/2012



MILWAUKEE – Danfoss VLT Drives introduces Vertical Bypass Panel Assemblies.  These packed drive solutions are structured around Danfoss VLT® HVAC Drives to deliver robust variable speed drive performance in HVAC applications, with market-preferred bypass controls and maximum geometric flexibility to meet strict installation constraints.

“Vertical Bypass Panel Assemblies are constructed of the same high quality components and design to deliver the same high performance as our traditional panels, but with a sleek vertical layout and smaller footprint that requires half the horizontal width of traditional panels,” says Steve Gmeinder, Product Manager.

Vertical Bypass Panel Assemblies feature a UL Type 1 / NEMA 1 design, and are UL/CUL 508 listed and seismically certified.  Inherent phase loss / imbalance and brown-out protection prevents product damage and downtime in adverse power quality installations.  They are available in non-bypass or 3 contactor bypass configurations, and provide 24 VDC control power for all but the largest sizes.

“The engine driving the Danfoss panel dependability is a 24 VDC switch mode power supply that greatly improves performance and dependability beyond traditional CPT power designs.  The panel power supply on P2, P3 and P4 frame sizes provides steady and dependable control power, even when the input voltage drops up to 30 percent, virtually eliminating contactor malfunction due to brown-out conditions or phase loss.  On P5 frame sizes, a voltage sensing relay provides similar protection,” explains Gmeinder.

Danfoss drives provide superior performance due to the robust DC link reactor that is standard in every VLT HVAC Drive.  This device offers comparable harmonic performance to AC input reactors without detrimental input voltage reductions, and without the extra heat that would typically be removed by additional fans or other devices.

Options available with Vertical Bypass Panel Assemblies include 208V – 240V through 60 HP, and 460V and 600V through 125HP.  Additional options to satisfy specific application needs include:

·         Fused disconnect or circuit breaker disconnect

·         Electronic or electromechanical bypass

·         100,000 Amps Short Circuit Current Rating (100KA SCCR)

·         Embedded fieldbus communication protocols

·         Various fieldbus and I/O option cards
