TRANSCRIPT
TCI’s KLC & KLCUL dV/dTGuard Output Filters Provide SuperiorPatented Protection for MotorsAs the technology of Pulse Width Modulated (PWM)Drives are incorporated into various applications andprocesses, the increased energy savings and decreasedmaintenance on Drives can be offset by increases inMotor failures.The dV/dTGuard product family has been designedas an engineered solution for motor failures due tothe reflected wave phenomenon. Designed to beinstalled at the output terminals of the Drive,dV/dTGuard Output Filters provide effortlessinstallation, convenient accessibility and enhancedmotor performance and durability. Available in aUL/CUL version or in our original version, theseproducts provide the outstanding performance thatour customers have come to expect from TCI.
Manufacturer’s WarrantyKLC and KLCUL Output Filters are warranted againstManufacturer’s defect for one year from the date oforiginal purchase.
Performance GuaranteeProperly applied and sized for the application, a KLC or KLCUL output filter is guaranteed tolimit the peak voltage and reduce electrical stress on the motor insulation. If a KLC or KLCULfails to reduce peak voltages, TCI will take back the output filter and pay shipping both ways.(Offer valid for 60 days from purchase date.)
Drawings/SpecificationsAutocad compatible *.dxf drawings and Acrobat Reader compatible *.pdf drawings of all KLCand KLCUL dV/dTGuard Output Filters are available at www.transcoil.com or by contacting TCIat (800) 824-8282.
Typical Problems, Superior Solutions with KLC ProductsThe Reflective Wave PhenomenonVariable Frequency Drives generate useful “fundamental” voltage and frequency using Pulse WidthModulation (PWM) for adjusting the speed of an AC motor. The Drive’s inverter circuit “switches”(transitions from the off state to the on state) rapidly, producing a carrier containing the fundamentalvoltage and frequency. Voltage wave reflection is a function of the voltage rise time (dV/dT) andthe length of the motor cables. The impedance on either end of the cable run does not match,causing voltage pulses to be reflected back in the direction from which it arrived. As these reflectedwaves encounter other waves, their values add, causing higher peak voltage. As wire length orcarrier frequency increases, the overshoot peak voltage also increases. The dV/dT Motor ProtectingOutput Filters have been designed to limit peak voltage and increase voltage rise time. In specificapplications, the KLC has peformed with cable runs of up to 3,000 feet.dV/dT and Reflective Wave unsuppressed causes Motor failures• Peak Voltages on a 460V system can reach 1200 to 1600 V, causing rapid breakdown of motorinsulation, leading to motor failure. On 575 V systems, the peak voltages can easily reach 2100V. If this is left uncontrolled, insulation failure may occur.• The same peak voltages that damage the motor can also damage the cable. Since the KLC andKLCUL filters are designed to be placed at the output of the Drive, these units will also protectthe cable runs.The added inductance of a KLC or KLCUL filter will also help reduce motor heating, motor noise,and motor vibration by reducing the current harmonics in the system.

Please note that although an open style KLC can be changed in the field to an enclosed version, the same is nottrue for the KLCUL style filters. The enclosed version of the KLCUL filters uses an entirely different style of enclosure.* Denotes the change from a wall mount unit to a floor mount unit and a change in the mounting diagram.
While peak voltages can reach 1600V or more, it is important to note that these same spikes can have a rise time,dV/dT, in excess of 7500V/µs. Such high rise times can cause significant damage to the motor windings and theinsulation system, resulting in premature motor failure. The life of the motor can be greatly extended by limitingboth the magnitude of the voltage spikes to levels below 1000V and the dV/dT at the motor terminals to levels lessthan 1000V/µs on 480V systems.

Single Drive, Single Motor• Provide sufficient ventilation. Unit loss characteristics can be found on the selection charts on the
previous pages.• Mount the unit within ten (wire) feet from the drive• Insure the Drive’s carrier frequency is set to 8kHz or below and the operating frequency is set to 60 Hz or
below. A carrier frequency of 4 kHz is recommended.• Connect the drive output leads to the A1, B1, and C1 terminations of the KLC or KLCUL unit. A2, B2, and
C2 service the wire to the motor.• If system requirements are outside of the above recommendations, please contact the factory.
Upon system start up, observe the KLC or KLCUL unit for a minimum of 30 minutes. Under normal operatingconditions, the filter components will be too hot to touch (in excess of 100 degrees C). However, if there isany noticeable component discoloration , remove the filter from the system and consult the factory.
Considerations when Specifying and Selecting KLC/KLCUL FiltersKLC and KLCUL filters may be used in single Drive and Motor applications as well as a single Drive controllingmultiple motors. In each case, there are some application guidelines that need to be followed in order to insurethe optimum performance of your KLC or KLCUL Filter. Filters are sized based on the full load amps of themotor or motors.
Single Drive, Multiple Motors• Provide sufficient ventilation. Unit loss characteristics can be found on the selection charts on the
previous pages.• Mount the unit within ten (wire) feet from the drive• Insure the Drive’s carrier frequency is set to 4 kHz or below and the operating frequency is set to 60 Hz
or below.• Connect the drive output leads to the A1, B1, and C1 terminations of the KLC or KLCUL unit. A2, B2, and
C2 service the wire to the motor.• The length of each motor lead should be less than 500 feet and the sum total of all the leads should be less
than 1500 feet• Total number of motors should be 10 or below

Do not operate the Drive/KLC configuration into unterminated long leads as the gross impedance mismatch willcause excessive heating in the unit’s damping resistors.
It is recommended that the unit not be mounted above the Drive, as this may affect the ambient temperature ofthe filter.
