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.
