1321 Power Conditioning Transformer

Product Information

The 1321 Power Conditioning Products by Allen-Bradley are
designed to help protect equipment and ensure optimal performance
in the presence of power line disturbances. The product line
includes various components such as line reactors, reflective wave
reduction devices, three-phase isolation transformers, common mode
chokes, and DC link chokes. These products are designed to absorb
power line disturbances, reduce harmonic distortion, and provide
surge protection for drives and motors.

1321-3R, 1321-3RA, and 1321-3RB Series Line Reactors

The line reactors can be applied at the input or output of a
drive to protect against surges, spikes, and harmonic distortion.
They help ensure reliable operation and extend the lifespan of the
equipment.

1321 Reflective Wave Reduction (RWR) Devices

The RWR devices are designed to reduce reflective wave phenomena
that can occur in electrical systems. They help minimize voltage
spikes and improve system stability.

1321-3TH/3TW Series Three-Phase Isolation Transformers

These isolation transformers provide both voltage change and
isolation for variable speed drives. They are harmonic compensated
and IGBT protected to ensure optimal performance.

1321-Mxxx Common Mode Chokes

The common mode chokes help mitigate electromagnetic
interference (EMI) by reducing common mode noise in electrical
circuits. They are suitable for various applications requiring EMI
suppression.

1321-DC DC Link Chokes

The DC link chokes are used in DC power systems to reduce ripple
currents and improve stability. They help protect the equipment
from voltage fluctuations and ensure smooth operation.

Product Usage Instructions

Applying Allen-Bradley Line Reactors:

At the Input of the Drive:

Connect a line reactor at the input of the drive to protect
against surges, spikes, and harmonic distortion in the incoming
power lines.

At the Output of the Drive:

In long motor lead applications, place a load reactor between
the drive and motor to reduce dv/dt and motor terminal peak
voltages. This helps protect the drive from surge currents caused
by rapid load changes.

With Multiple Drives:

For multiple drives connected to a common power line, each
drive should have its own line reactor. This provides individual
filtering between drives, minimizing crosstalk and ensuring optimal
surge protection.

With Multiple Motors:

When controlling multiple motors with one drive, a line reactor
can be used between the drive and all the motors. Size the line
reactor based on the total motor/load horsepower.

With Single-Phase Input:

For single-phase applications, a three-phase reactor can be
used 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 determines the total reactor
inductance.

Please refer to the Allen-Bradley Drives Technical Support
resources provided for additional guidelines and safety
information.

Product Overview
Allen-Bradley reactors help keep equipment running longer by absorbing many of the power line disturbances that can shut down your drive. Allen-Bradley isolation transformers can provide both voltage change and isolation for your variable speed drive. These designs are harmonic compensated and IGBT protected to help assure optimum performance in the presence of harmonics.

Selecting the Correct Impedance Rating

Why is the Right Impedance Rating Important?
Selecting the correct impedance rating is critical for your job. An impedance value that is too low may not limit peak current. An impedance value that is too high may reduce input voltage. Allen-Bradley line reactors offer two impedance ratings.

3% Impedance Rated Reactors to Reduce Spurious Trips
Allen-Bradley line reactors that are rated at 3% are typically sufficient to absorb line spikes and motor current surges and will help prevent spurious tripping of drive and circuit breakers in most applications.

5% Impedance Rated Reactors to Reduce Harmonic Content
Allen-Bradley reactors that are rated at 5% are best for reducing harmonic current and frequencies. These line reactors help comply with IEEE-519 (not normally used as load reactors).

Voltage Spike Protection
Voltage spikes on AC power lines can cause elevation of the DC bus voltage, which may cause the drive to trip on an overvoltage condition.
3% impedance reactors are effective at helping to protect drives against voltage spikes and spurious tripping. Allen-Bradley line reactors absorb these line spikes which help protect the drive from spurious tripping and damage.

Sizing Guidelines

Fundamental amps are used for sizing the reactor to be equal to or slightly higher than the total motor FLA. Sizing reactors to drive ampere ratings alone may result in mis-sizing the reactor.

1321 Reflective Wave Reduction (RWR) Devices

1321 Power Conditioning Products

Description of Reflected Wave Phenomenon
The inverter section of a drive does not produce sinusoidal voltage, but rather a series of voltage pulses created from the DC bus. These pulses travel down the motor cables to the motor and then reflected back to the drive. The reflection is dependent on the rise time of the drive output voltage, cable characteristics, cable length, and motor impedance. If the voltage reflection is combined with another subsequent pulse, peak voltages can be at a destructive level. An IGBT drive output may have reflected wave transient voltage stresses of up to twice (2 pu or per unit) the DC bus voltage between its own output wires. Multiple drive output wires in a single conduit or wire tray further increase output wire voltage stress between multi-drive output wires that are touching. Drive #1 may have a (+) 2 pu stress while drive #2 may simultaneously have a () 2 pu stress.
For more details, see the Wiring and Grounding Guidelines for PWM Drives, publication DRIVES-IN001.

Applying RWR Devices

At the Output of the Drive
In long motor lead applications, an Allen-Bradley 1321 RWR located between the drive and motor helps to reduce dv/dt and motor terminal peak voltages. The use of an RWR device also helps protect the drive from surge currents that are caused by rapid changes in the load.
· Protect motors from long lead effects · Reduce output voltage dv/dt · Extend semiconductor life · Reduce surge currents · Reduce motor temperature · Reduce audible motor noise

Motor Protection
Allen-Bradley Reflective Wave Reduction devices can help protect motors from high peak voltages.
For IGBT drive applications with long drive-to-motor lead lengths, Allen- Bradley RWR devices can help protect against fast dv/dt rise times.

1321 Power Conditioning Products

1321-Mxxx Common Mode Chokes

1321-Mxxx Common Mode Chokes can be installed with the following Allen-Bradley AC drives.

· PowerFlex® 4-Class · PowerFlex 520-Series · PowerFlex 7-Class

· PowerFlex 750-Series · 1305 · 1336 PLUSTM

· 1336 PLUSTM II · 1336 IMPACTTM · 1336 FORCETM

When installed at the drive output the common mode choke helps to guard against interference with other electrical equipment (Programmable Controllers, sensors, analog circuits, and so forth). In addition, reducing the PWM carrier frequency reduces the effects and lowers the risk of common mode noise interference.
