VFD Motors
HVAC fans and compressors use variable frequency drive (VFD) motors. Ensuring the ac motors speed up and slow down predictably, safely, and efficiently prolongs equipment life. Littelfuse offers many electronic components to achieve that goal, including power bridges for current switching, transformers for ground fault protection, and motor protection relays technicians can monitor via smartphone.
