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. The 1321-3TW027-AA transformer reduces the DC/DT and motor terminal peak voltages. It also extends the life of the semiconductor. The transformer comes with a primary delta and a secondary wye winding. The winding is normally manufactured using aluminum.
The 1321-3TW027-AA isolation transformer offers Class 220 protection for a temperature of 150 degrees Celsius above the 40 degrees Celsius ambient temperature rating. The drive can be operated at up to a height of 1000 meters above the sea level without any reduction in the performance. The enclosure of the drive is a heavy-duty ventilated enclosure with an IP 32 protection rating. By using the mounting hardware, the transformer can be wall mounted. The 1321-3TW027-AA isolation transformer is known to be 98% efficient for normal working conditions. It comes with an impedance rating within 4 to 6% nominal. It has a K factor of 4. The transformer is listed with the UL standards for its short circuit withstand capability.
