The S75SHDW is a type of dual, non-directional, thyristor switch, typically used for high speed on/off operation of low-voltage, mid-voltage, and high-voltage power circuits. It is a high-speed, solid-state switching device that enables control of various AC and DC current applications. The S75SHDW is designed to operate with a wide range of voltage and current ratings, providing safe, reliable control of connected loads.

The S75SHDW is used for the most demanding applications such as load switching, arc suppression and phase balancing, as well as for general-purpose switching of motors, isolating transformers, and inverter circuits. It has the ability to switch high current loads, such as motors, at a very fast rate, allowing for precise control and improved load switching performance.

The S75SHDW uses two thyristors in a non-directional design, which makes it suitable for fast, repetitive switching, and which ensures that the current is always able to flow in either direction. The thyristors in the switch are held in an open circuit state until triggered by an external electrical signal. Once triggered, the thyristors turn on in rapid succession, providing a controlled high-speed switching of the electrical load. The S75SHDW is designed to provide accurate phase control and fast switching time, and is capable of handling large loads with short circuit current ratings of up to 30,000 Amps.

The S75SHDW offers a number of features, such as a wide range of voltage and current ratings, high surge withstand capability, induced over-voltage protection, and a low voltage drop when switched on. Additionally, the switch incorporates advanced protection functions such as reverse current limiting, over-current sensing, thermal protection and over-temperature shut-off. These functions provide protection to connected equipment, ensuring reliable and safe operation in even the most demanding applications.

In summary, the S75SHDW is a high performance, dual, non-directional thyristor switch that offers an efficient and reliable solution for high-speed switching in a wide range of electrical applications. The switch is designed to provide precise control and fast switching time, as well as a number of advanced protection features, allowing it to be used for a wide variety of applications. With the right combination of features, the S75SHDW is suitable for a variety of uses, from load switching to arc suppression, phase balancing and general purpose switching.
