IP 21 and IP 54
The new drives come in the enclosure classes IP21 (NEMA and UL Type 1) and IP54 (NEMA and UL Type 12).
Low risk drives
Built-in DC Link Reactors ensures a low level of harmonic disturbances compared to other high power drives. PCB’s are conformal coated per IEC 60721-3-3, class 3C3 (standard on VLT® all High Power drives)
Class A2 RFI filters are standard, and Class A1 filters optional for the 380-480V platform.
Innovative cooling
The innovative back-channel cooling in the HVAC series is consistent with other VLT® high-power drive series.
Built in options
Several options are factory integrated, such as fuses, mains switch/disconnect, contactors, circuit breaker, cabinet light & outlet, space heaters & thermostat, door interlocks, manual motor starters, auxiliary low voltage power supply, integrated emergency stop pushbutton, and external temperature monitoring.
Supported by VLT® software
The high power HVAC drives are supported by the VLT® Setup Software MCT 10 and the VLT® Harmonics Calculation Software MCT 31.
