Triad Magnetics’ Universal Chassis Mount power transformers are specially designed to offer optimal performance when integrated into full wave center tap circuits and bridge circuits, when those circuits utilize rectifiers made of silicon or selenium. They also perform excellently in voltage doubler circuits at half the rated current.

Universal Chassis Mount power transformers offer a huge array of nominal secondary voltages. For example, the F-90 series — the most capable models, designed for use with silicon diode rectifiers to supply DC voltages for transistors in innumerable applications — can generate 23 different output voltages, ranging from 7 V to 40 V, by connecting secondaries in a series. The secondary voltage is selected by primary taps.

Description N/A Triad chassis mount power transformers provide maximum performance when integrated into full wave center tap or bridge type circuits with silicon or selenium rectifiers. The secondary voltages are selected by primary taps. The secondaries of the Series F-90 transformers may be connected to provide a wide variety of output voltages. The Series F-90 transformers are designed for use with silicon diode rectifiers to supply the DC voltages for transistors in their various applications. They are intended for use with full wave center tap or bridge rectifiers, but may be used with voltage doubler circuits at one-half of the rated current.
