DT1145 Description

Short technical summary and product information.

The ESI DT1145 is a Dekatran Decade Ratio Transformer, a specialized component for precise electrical measurements and adjustments. It offers a wide ratio range from 0.0000 to 1.11100, controlled through 4 decades, allowing for fine-tuning of signal ratios.

 

This transformer operates within a frequency range of 50 Hz to 5 kHz, with an input voltage capability of 0.35f or 350 V maximum. Its output impedance is characterized by R = 2.5 Ω and L = 100 µH, and it has an input impedance of approximately 400 kΩ at 20 V and 400 Hz. The terminal linearity is ±10 ppm over the 50 Hz to 1 kHz range.

 

Constructed with a metal case, the DT1145 is designed for chassis mounting, fitting into equipment for integrated use. Its dimensions are a diameter of 3.35 inches (8.5 cm). The unit requires no external power and has no sound reproduction output, indicating its function as a passive measurement instrument.
