Drive reactors mount the DIN rail

A TCI product story
Edited by the Engineeringtalk editorial team Sep 6, 2005

A new range of DIN rail drive reactors promises to reduce installation time and costs.

TCI has released a new range of DIN rail drive reactors, designed to reduce installation time and cost.

The reactors are designed to be compatible with any 35mm DIN rail.

These reactors mount to either standard steel high profile or heavy duty steel DIN rails.

Using DIN rail drive reactors reduces installation time by over 75%.

Installation requires no specialised tools.

Simple three lines in, three lines out means clean cable layouts and improved cabinet organisation.

TCI is also releasing UL listed reactors.

KDR optimised drive reactors and KLR line reactors are now available as UL listed products.

UL Type 1 and UL Type 3R enclosures are available for UL listed reactors.

The enclosure selected for your reactor will depend on two things: the degree of protection the reactor must have against indoor and outdoor environments as well as the certification requirements of the installation.

TCI offers NEMA 1 enclosures, UL Type 1 and UL Type 3R enclosures.

NEMA 1 enclosures are best used when the application is indoors and you need protection against dust.

The vent slot size provides cooling for the unit.

KDR and KLR reactors fit mechanically in the smaller NEMA 1 enclosures.

When the application is indoors and requires a larger space for wire bending, UL Type 1 enclosures are the optimal choice.

UL Type 1 enclosures provide protection against a limited amount of falling dirt as well as a vent slot size that provides cooling for the unit.

This larger enclosure provides the necessary space for heat dissipation.

Outdoor applications require an enclosure that provides a degree of protection against falling rain and the formation of ice on the enclosure.

UL Type 3R enclosures are intended for outdoor use.

This larger enclosure provides space for wire bending and adequate space for heat dissipation.

TCI reactors applied to the line side of a VFD drive will greatly improve the overall performance of the drive.

The additional circuit inductance will reduce AC voltage waveform line notching, DC bus overvoltage trips, inverter overvoltage, poor total power factor and crosstalk.

The addition of a reactor 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.
