Product Description :

Isolation Transformers at Sylvan are designed to block interference caused by neutral of the line. It is specially constructed to eliminate all types of electrical noises like common mode noise, etc. This type of transformer isolates primary and secondary coils. A separated neutral to ground bond on the secondary side is created to be used as a separately derived source to combat current loops.

A grounded Faraday shield between the primary and the secondary is created using high insulation materials with special shielding techniques that attenuate common mode noise as well minimize transverse mode noise. The specially selected core with its magnetic properties exhibit sufficient leakage inductance to attenuate noise with proper transfer of fundamental power frequency. The Ultra Isolation transformer is designed with split winding construction and bifilar connections to reduce coupling capacitance of winding.

K-Rated Isolation Transformer :

The overall function of the ULTRA K Isolation Transformer is to deliver conditioned power to a non-linear high-harmonic current load and operate at safe temperatures while minimizing the harmonic current delivered to the power grid. An additional function of the ULTRA K is to attenuate both common mode and transverse mode noise going to the load. The product is offered with four different K-Factors (K-4, K-7, K-13 & K-20) standard. The K-Factor is a means of rating the transformer's ability to withstand the heating effects of harmonic and fundamental current flowing in the transformer. Utilization of the proper K-Factor is absolutely essential in every installation. If too low K-Factor is used, it can result in failure, fire, overheating, and wave form distortion.

What K-Factor to use?

K-Factor transformers are available from a K-4 rating to a K-20 rating.

- A K-4 Rated transformer is rated for 35% nonlinear load.
- A K-7 Rated transformer is rated for 50% linear and 50% non-linear. The mix may be 50/50 at one point in time and change to 80/20 in the future.
- A K-13 Rated transformer is rated for 75% non-linear loading. This transformer would take care of most present and future needs. There is a higher initial but it is worth it.
- A K-20 Rated transformer is for installations that have an unusually high harmonic or non-linear content. Here again there is a price premium for the additional insurance.
