Allen-Bradley 1321 Power Conditioning Products 1321-3TW027-AA

The 1321-3TW027-AA isolation transformer is an Allen-Bradley isolation transformer unit. It is used to meet different AC drive protection needs that are created due to AC line disturbances. It protects the drive from power line disturbances. It also helps extend the life of the drive by absorbing the disturbances that enter it. This isolation transformer is harmonic compensated and the IGBT brake system that it has is protected and it offers optimum drive performance. It protects the host drive against surges and spikes on the incoming power lines and it helps reduce the harmonic distortion. It can help eliminate the phenomena of nuisance tripping and voltage notching. It improves the true power factor of the host AC drive.
