Write Your Own Review
The VLT HVAC drive has built-in intelligence to give optimal process control to heating, ventilation and air conditioning (HVAC). It is simple to use and extremely cost-efficient, featuring a number of functions that are ideal for use with pumps, fans and compressors to save energy, meet environmental regulations and reduce costs in modern buildings.
The VLT HVAC drive has a compact, robust design and is ideally suited to locations where space is restricted. A selection of safety features, such as Safe Torque Off and Safe Maximum Speed, protect both applications and their operators.
Enclosures can be purchased separately, up to IP66, and an additional option available upon purchase is a unique coating to provide added protection for the circuit boards. Integrated DC chokes and RFI filters safeguard installations by minimizing harmonic distortion and electromagnetic.
