Various Dyco Electronics' magnetics and power transformer products are used for military and commercial capabilities such as critical military applications, and with several companies coming from many areas of the railroad industry. A power transformer normally operates from either 60 Hz, or 400 Hz alternating current. Each tiny domain must realign itself twice during each cycle, or a total of 120 times a second when 60 Hz alternating current is used. The energy used to turn each domain is dissipated as heat within the iron core. This loss, called HYSTERESIS LOSS, can be thought of as resulting from molecular friction. Hysteresis loss can be held to a small value by proper choice of core materials. |

Steel Lamination are thin pieces of high permeability iron stacked together to make a power transformer or choke core. The pieces are often formed in the shape of letters such as E, I or U which also define the power transformer configuration. i.e. E/I core. Split Bobbin Winding is the method of winding a power transformer whereby the primary and secondary are wound side-by-side on a bobbin with an insulation barrier between the two windings. |
Secondary Turns (Ns) are the number of turns of magnet wire in the secondary winding of a power transformer. If multiple secondary windings exist they are identified by a subscript number such: Ns1, Ns2, and so on. A choke is an inductor used in applications where there is a need to impede the alternating current in a circuit. Chokes are usually found in power transformer supply filters. |
