one-4-all international MEETS UL, VDE, IEC, CSA AND ALL COST & BETTER PERFORMANCE THAN PC BOARD Signals International Series of transformers is designed and constructed to TYPE meet all U.S. and international standards such as UL, VDE, IEC and CSA. This is accomplished by two factors: 1. The dual bobbin construction including an overall insulating shroud as in- dicated in the exploded view of constructional details. 2. The use of highly stable, high temperature material which more than meets UL flammability requirements. The insulation system results in very high isolation between primary and secondary windings and from either to the core (or ground). Hipot Test is 4000v RMS. The dual bobbin non-concentric design reduces capacitance and eli- minates the need for an electrostatic-shield. These parts are available in both PC Board and Chassis Mount types from 2.5 to 175 va. Coil winding and wire termination are simplified by the bobbin con- struction and the method of winding. The dual windings, when possible, are wound bifilar so that all anchor and insulating tapes are eliminated. Also, since the windings are electrically balanced, there are no primary cir- culating currents and, if the secondaries are series-connected for a FWCT recti- CSA Certification tier, the balance makes filtering easier. vailable The bobbin wali slots allow for all leads to be brought out of the winding area CA\ for termination. As a result, all wire crossovers and insulating pads are eli- Cy minated. The insulating shroud positions both bobbins accurately for core stack- ing and also provides the barriers for the 4000v RMS Test Voltage. These design improvements lower manufacturing costs. As a result, the series Part No. VA Secondary RMS Rating is truly universal and can be sold at lower prices than previous split bobbin (Size) Series Parallel and PC types -2.5- : 1 .T. 2 . . ree . . aco te 23 ioy et S oan Ey 6 Opn Again, Signal is there first with the best and at lower cost. 14A-10-10 | 10.0 1OV CT. @ 1.0A SV @ 2.0A 14A-20-10 | 20.0 10V CT. @ 2.0A 5V @ 4.0A 14A-30-10 | 30.6 10V C.T. @ 3.0A 5V @ 6.0A & 7 PRIMARIES ARE DESIGNED TO 14A-56-10 | 56.0 10VC.T. @ 5.64 SV @ 11.2A .
