Description
TOT-74
The transformers coordinating alarm the low frequency of TOT-74 are intended for work in the amplifiers of sound frequency of household and industrial function manufactured in the form of independent assembly units or as a part of household REA.
Transformers of the THAT type are used in devices of the low-frequency paths executed on semiconductor and electrovacuum devices in the equipment with printed circuit wiring.
Transformers of the THAT type are developed especially for schemes of printed circuit wiring.
The arrangement of conclusions of transformers is similar to a pin-connection diagram of electrovacuum devices and relay. There is a key and additional marking of the first conclusion on the side surface of the transformer a red point. Counting of conclusions is made clockwise from installation. At the same time the first conclusion is located in the left top corner. The framework of transformers receives additional rigidity from reinforcing by its rigid conclusions between which distance is equal to a step of a coordinate grid of the printed circuit board.
Main technical characteristics of the transformer of the THAT type:
• Working range of effectively reproduced frequencies...... 300... 10000 Hz,
• Range of rated power...... 0,025... 25 B*A,
• Resonant frequency...... no more than 1000 Hz,
• Maximum value of test tension...... 500 V,
• Coefficient of nonlinear distortions at boundary frequencies of bandwidth 300... 10000 Hz...... no more than 5,
• Coefficient of amplitude-frequency distortions in the range of frequencies of 300... 10000 Hz...... ±2 dB,
• Maximum amplitude of alternating entrance voltage of transformers...... 140 V,
• Limits of change of entrance resistance of transformers...... 13... 22000 Ohms,
• Maximum tension of primary winding...... 100 V,
• Resistance of loading of transformers...... 4... 4000 Ohms,
• The maximum constant tension on transformer windings...... 100 V,
• Isolation resistance between windings, and also between each winding and a magnetic conductor...... 1000 Ohms,
• Maximum deviation of coefficient of transformation...... ±5,
• Ambient temperature......-60... 125 °C.
