BENEFITS OF USING LINE/LOAD REACTORS
Guard-AC line/load reactors help keep your equipment
running longer by absorbing many of the power line disturbances
which otherwise damage or shut down your
inverters, variable speed controllers, or other sensitive
equipment. They are the modern technology solution to
inverter and drive application problems. Guard-AC
reactors are harmonic compensated and IGBT protected
to assure optimum performance in the presence of harmonics.
They are very effective at reducing harmonics
produced by inverters and drives, and in most cases
will help you to meet IEEE 519. Use our harmonic compensated
reactors on either the input or output of an
adjustable speed drive/inverter. There is no need to derate
our "harmonic compensated" reactors for harmonics.
- Protect Motors from Long Lead Effects
- Reduce Output Voltage dv/dt
- Virtually Eliminate Nuisance Tripping
- Extend Semiconductor Life
- Reduce Harmonic Distortion
- Reduce Surge Currents
- Reduce Motor Temperature
- Reduce Motor Audible Noise
- Improve True Power Factor
- Helps Meet IEEE 519 or EN 61000-3-4
Agency Approvals
Guard-AC reactors are manufactured to the exacting standards
of MIL-I-45208, VDE-0550, are UL recognized and
CSA certified. All UL approvals are for USA and Canada.
· CSA File #LR29753, open units up to 2400A
· UL-508 File #E180243, open and enclosed up to 2400A
All higher current reactors offer UL recognized insulation
systems and construction.

Impedance Ratings
3% impedance reactors are typically sufficient to
absorb power line spikes and motor current surges.
They will prevent nuisance tripping of drives or circuit
breakers in most applications.
5% impedance reactors are best for reducing harmonic
currents and frequencies. Use them when you must
comply with IEEE 519, to reduce motor operating temperature,
or to reduce motor noise.
NOTE: The actual effective impedance of the reactor
changes with actual fundamental current.
