The VLT-HVAC line is offered in 1.5 through 600 hp at 460 and 600 VAC, and 1.5 hp through 60 hp at 208 and 230 VAC, in either NEMA/UL Type 1 or 2 enclosures. The variable-frequency drives have a modular design that allows users to buy only what is needed for a specific application. The range of standard I/O can be expanded through factory- or field-installable ridged, self-identifying option cards that fit under the drive keyboard. With enhanced HVAC-specific capabilities and custom programmability, including integral cascade control, fan control and compressor control features, each drive provides simple, out-of-the-box operation.
