Drive Components Unico offers a variety of components that can be used in the integration of complete drive systems. - Isolation Transformers Isolation transformers can be used to provide a buffers between power lines and drive systems, to translate voltage levels, or to provide 12-pulse harmonic reduction. - Line Reactors Line reactors for conditioning the incoming power source are available with 3% and 5% ratings in both open and enclosed versions. - Harmonic Filters Unico' s 7110 series of harmonic filters provides a cost-effective means of satisfying IEEE 519 harmonic requirements without the inherent problems of conventional filters. - Output Filters Output filters are available to eliminate transient voltages in long cable runs that could damage motor insulation. - Braking Resistors Braking resistors used to absorb regenerated energy are available in standard ratings of 5% , 10% , and 20% of the associated drive capacity. - Other Components Other components such as ammeters, voltmeters, circle chart recorders, control transformers, and operator devices, can be supplied to satisfy specific needs.
