2 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. Impedance Rating 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. % Impedance = I (50/60 Hz fundamental) 2 f L 3 100 V (L-L) 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 #LR29753-13, 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.

Even at 150 percent of their current rating, these reactors still have 100% of their nominal inductance. This assures maximum filtering of distortion even in the presence of severe harmonics and best absorption of surges. The typical tolerance on rated inductance is plus-or-minus 5 percent.

They are designed to carry full rated fundamental current plus handle current and frequencies associated with harmonics up to 50 percent more. TERMINALS are provided as standard to save installation cost and minimize panel space. Finger proof (IP20) terminals are provided through 45 amps, solid copper box lugs above that to 400 amps. Tab type terminals are available as an option. EPOXY IMPREGNATION minimizes audible noise in the reactor and enhances structural integrity. IGBT PROTECTION allows all MTE standard reactors to be used on the output of variable frequency drives including IGBT types with switching frequencies up to 20 KHZ. A premium dielectric system is utilized to protect the first, last and end turns from the potentially high circuit peak voltages and fast dv/dt which are experienced in applications with long leads between the inverter and motor. Additionally, the general dielectric system of each reactor meets UL-506 (4000 volts rms). HIGH SATURATION CURRENT RATING of Guard-AC reactors maximizes their surge current protection capability. Guard-AC reactors absorb many of the power line disturbances which cause nuisance trips on voltage source inverters.

For Input or Output of Adjustable Speed Drive/Inverter Systems This table is suitable for selection of both input and output reactors because their harmonic compensation and IGBT protection allow them to be used in either application. Specific current and inductance ratings are indicated on Page 7. Consult factory for any special applications (higher current, motor rating different than controller rating, etc.) Select Guard-AC line/load reactors based upon motor horsepower, (or kilowatts) and voltage. Verify that the motor full oad amperer rating is within the fundamental current rating of the reactor, and the drive/inverter rating is within the maximum continuous current rating of the reactor (See Page 7). For higher or lower current ratings, consult factory. For other voltages or frequencies, consult factory. Single phase reactors are also available, consult factory for proper selection. Custom or modified reactors are available to meet specific requirements for special applications such as harmonic filters, consult factory for assistance.

Without Reactor With 5% Impedance Reactor LC Type (dv/dt) Long Lead Filters These motor protection filters are available to improve the inverter output wave form from a PWM type to a nearly sinusoidal wave form. Without Filter With LC Filter Voltage Spike Protection A 3% impedance reactor is very effective at protecting against damage to or nuisance tripping of AC voltage source inverters, due to voltage spikes. Voltage spikes on the AC power lines cause elevation of the DC Bus voltage which may cause the inverter to trip-off and indicate an over-voltage protection condition. Use reactors to absorb these line spikes and offer protection to the rectifiers and DC Bus capacitors while minimizing nuisance tripping of the inverter.

Applying Line/Load Reactors Input to Inverter/Drive: On the input of an electronic motor speed controller, line reactors protect sensitive electronic equipment from electrical noise created by the drive or inverter (notching, pulsed distortion, harmonics). They also protect the controller from surges or spikes on the incoming power lines, as well as reduce harmonic distortion. They help to meet the requirements of IEEE 519. Output of Inverter/Drive: In long motor lead applications use reactors (IGBT protected) between the inverter and motor to reduce dv/dt and motor terminal peak voltage. The use of a load (output) reactor also protects the controller from a surge current caused by a rapid change in the load, and even from a short circuit at the load. Our reactors also reduce operating temperature and audible noise in motor loads. Harmonic compensation and IGBT protection of all Guard-AC reactors allows standard units to be used here with confidence. They improve the waveform integrity, thus enhancing motor performance and system efficiency. Multiple s: Multiple drives or inverters on a common power line require one reactor per controller. Individual reactors provide filtering between each controller (reduce crosstalk) and also provide optimum surge protection for each unit. A single reactor serving several controllers does not provide adequate protection, filtering or harmonic reduction when the system is partially loaded. Multiple Motors: When more than one motor is controlled by a single drive, a single reactor can typically be used between the controller and the motors, as illustrated. The reactor should be sized based on the total motor/load horsepower.
