SRF1260-681M

Signal transformers are electrical components used to manage the transfer of electrical signals and energy between two or more electrical circuits. By modifying the output voltage, they are also called voltage transformers. SRF1260-681M is an example of signal transformer widely used in array applications. This article explains the application field and working principle of SRF1260-681M.

SRF1260-681M is a digital signal transformer with two independent winding channels used to transfer data in two directions, as well as providing an additional path of current in one winding channel. It is a high voltage transformer, with a rated operating voltage of 1260V and a dynamic operating voltage of 1563V. With the dual winding channels, it is suitable for increased voltage drop due to an intense load, resulting in improved control and signal quality.

The SRF1260-681M is mainly used in arrays to provide multiple channels for the same signal, reducing the amount of pins needed to achieve the same result. For example, the transformer is used in the context of power management of power supplies, providing isolation and protection against overloading. It also offers direct current only (DC) and alternating current only (AC) circuits, enabling direct power distribution.

SRF1260-681M’s transformer core is composed of ferrite material with a high saturation level and low countermeasure losses. Its construction also ensures a wide temperature operating range (down to -40 Celsius) and minimized electromagnetic interference (EMI). The winding channels of SRF1260-681M are designed to simultaneously support high-current and low frequencies, which helps reduce the noise and buzzing issues often associated with digital signals.

The mechanism of the SRF1260-681M is based on Faraday’s law of induction. When the primary coil of the transformer is supplied with current, a varying magnetic flux is produced. This flux links the secondary coil and induces a voltage in it at the same frequency, but with a different amperage. This ratio between the primary and secondary coil determines the voltage transformation of the transformer and typically ranges from 200:1 to 400:1.

In conclusion, SRF1260-681M is a signal transformer designed for array applications. Its dual winding channels support intense loads and long cables lengths. Its ferrite core material and winding construction ensure tolerance against high temperatures and EMI. Furthermore, the transformer works based on Faraday’s law of induction. Each channel provides an optional current path for direct power distribution, and overloading is avoided thanks to its high voltage design.
