RECTIFIER TRANSFORMERSRECTIFIER TRANSFORMERS

RECTIFIER TRANSFORMERS

Each transformer has the winding arrangement and terminal numbering shown in the schematic diagrams above. The

primary windings may be used in series to raise or lower the secondary voltage output. A variety of combinations is possible

using the taps on both windings for “Aiding” or “Bucking” action.

Designed for 117 V, 50/60 cycle operation; however, may be satisfactorily operated at 400 cycles.

The secondary winding of each transformer consists of two identical windings connected to terminals 8 & 9 and to 10 & 11

respectively. Use the tables showing the various output voltages for specific terminal connections as your guide. Many

combinations are possible other than those listed in the tables. All ratings shown are for normal convection air cooled

applications. Select only rectifiers capable of handling the output voltages and currents described.

When operating these transformers continuously at maximum rated output voltage and current and because of certain

other conditions, it is sometimes necessary to derate the rectified output current (D.C.) as much as 20%, in order to stay

within the recommended operating temperature limit of 105 degrees Centigrade. The type of rectifier circuit and load

(capacitive, inductive or resistive) determines the relative amount of current (RMS) in the transformer secondary winding.

The relationship of AC. to D.C. (secondary RMS current to rectified D.C. output) for typical circuits and loads is given in the

Technical Data on Page 38 of this catalog. Operating duty cycle, type of cooling (natural convection in free air or other-

wise) and the power line input voltage and frequency also have an effect on the transformer temperature. These things

should all be properly related to the results in any specific application.

The “RT-Series” of transformers may also be used in other rectifier circuits than the Full-wave C.T. and Full-wave Bridge shown

above. In circuits such as the Half-wave or Full-wave Voltage Doubler (symmetrical) and Full-wave Bridge, where a C.T.

connection is not required, both secondary windings may be connected in parallel, to double the RMS current that is

available from each secondary separately. The RMS voltage will, of course, be half of the amount available as that

obtained with the secondaries connected in series. Please refer to the adjacent data to obtain the secondary RMS current

as related to each rectifier circuit and type of load.

Voltages expressed in the tables are approximate and will vary within plus or minus two (2) Volts.
