Allen-Bradley isolation transformers can provide both voltage change and isolation for your variable speed drive.

3 The use of a load reactor also helps protect the drive from surge currents caused by rapid changes in the Multiple DrivesMultiple drives on a common Power line should each have their own line reactor. Individual line reactors provide filtering between each drive to help reduce any crosstalk while providing optimum surge protection for each Multiple MotorsWhen more than one motor is controlled by a single drive, a single line reactor can typically be used between the drive and all the motors. Size the line reactor based on the total motor/load Single-Phase InputA three-phase reactor can be used for single-phase applications by routing each of the two input Power conductors to the outside two coils, and leaving the center coil disconnected. The sum of the inductance of the two coils is the total inductance applied to the circuit. Contact Rockwell Automation technical Support for assistance in specifying the proper reactor.

An impedance value too low may not limit peak current. Too high of an impedance may reduce input voltage. Allen-Bradley line reactors offer two impedance Impedance Rated Reactors to Reduce Nuisance TripsAllen-Bradley line reactors rated at 3% are typically sufficient to absorb line spikes and motor current surges and will help prevent nuisance tripping of drive and circuit breakers in most Impedance Rated Reactors to Reduce Harmonic ContentAllen-Bradley reactors rated at 5% are best for reducing harmonic current and frequencies.

5 These line reactors help comply with IEEE-519 (not normally used as load reactors).Voltage Spike ProtectionVoltage spikes on AC Power lines can cause elevation of the DC bus voltage which may cause the drive to trip on an overvoltage impedance reactors are very effective at protecting drives against voltage spikes and nuisance tripping.
