Peripherals for AC and DC drives -active harmonic filters, passive harmonic filters, drive output filters, line reactors.
Trans-Coil International is the premier supplier of peripherals for AC and DC drives and a respected partner of drive manufacturers and distributors worldwide. Our products include active harmonic filters, passive harmonic filters, drive output filters, line reactors, and other high quality products that increase the value and improve the overall system performance of power inverters.
TCI has achieved ISO 9001:2008 certification, recognizing that the company’s quality management system meets criteria developed by the International Organization of Standardization of Geneva, Switzerland. This registration covers the Quality Management System for design and manufacture of peripheral products and services for the electronic power conversion industry.
TCI offers a number of solutions that reduce or eliminate harmonic distortion, including line reactors, passive harmonic filters, and active harmonic filters. With proper application, these harmonic filters are used to meet the IEEE-519 specification on harmonics.
The addition of a KDR Optimized Drive Reactor will limit the inrush current to the rectifier, rounding the waveform, reducing the peak currents and lowering the harmonic current distortion. Learn more about the KDR
The HG7 not only limits current distortion to less than 7% TDD, it also improves true power factor. Multiple package options result in the right filter configuration for the application. Learn more about the HG7
By actively monitoring the load current, the H5 determines the proper current waveform for injection into the system to maintain an acceptable level of harmonic distortion (TDD Reduction to 5% or better at Full Load). Learn more about the H5
High Frequency Noise Solutions
Unwanted high frequency electrical noise can cause equipment to malfunction. EMI (Electro Magnetic Interference) and RFI (Radio Frequency Interference) are two types of electrical noise.
The KRF filters use a combination of high requency inductors and capacitors to reduce noise in the critical 150kHz to 30MHz frequency range. Learn more about the KRF
Motor Protection Solutions
The V1k dv/dt filter provides motor protection by limiting voltage spikes below 1,000 volts for long lead applications. The KMG eliminates harmful dv/dt to result in a sinewave output.
The addition of a KDR unit to the output of a drive will dampen overshoot peak voltage, reduce motor heating and audible noise, helping to extend the life of the motor. Learn more about the KDR
Greatly reduces motor failures on VFD applications by limiting the magnitude of voltage spikes to levels below 1000 Volts and slowing down the rate of change of PWM switching by a factor of three or more. Learn more about the V1k
The KMG filter converts the PWM wave form to a near sinusoidal wave form, allowing sensitive applications to take advantage of the efficiencies and savings that PWM output power supplies and drives offer. Learn more about the KMG
