Thyristors Load Sequencing Controllers

Thyristors Load Sequencing Controllers are referred to as semiconductor devices, which enable the switching of electric currents. Invented in the year 1957, these equipments are used as control elements to regulate alternating currents, when high currents and voltages are employed. Thyristors Load Sequencing Controllers are widely used in heating applications, owing to their efficient power control. These devices are widely demanded courtesy their energy saving property. They surpass several process-supporting tasks viz., controlling heating in thermally insulated chamber known as kilns or lightning in spacious commercial halls.

Construction Of Thyristors Load Sequencing Controllers
Thyristors Load Sequencing Controllers have four layers of sporadic N and P type material. This allows the device to act as switches. They work when their gate is a recipient of an electric pulse. Thyristor power switches are most commonly applied for the contact free switching of AC loads. The control and power sections in the device are isolated electrically with the help of optocouplers. A varistor is attached on the output side, which acts as a protection against unexpected voltage surges.

Application Of Thyristors Load Sequencing Controllers
Thyristors Load Sequencing Controllers offer a much higher operation at extreme temperatures as compared to regular electromagnetic contractors. Some of the major Applications of Thyristors Load Sequencing Controllers are:

• This device is the preferred medium for resistive loads, more commonly known as incandescent light bulbs, as it reduces radio-frequency interference and distortion in harmony.

• Some power amplifiers are attached to transformers-coupled load, before transferring power, which is applied to the load. This indirect method is adopted to increase the efficiency of the amplifier. A Thyristors Load Sequencing Controller is used to operate the flow of current in the transformer-coupled load, without overheating the device.

• Another application is in the plastics packing and construction of industrial furnaces. The device is operated by switching of resistive inductive loads at elevated switching charge.

To sum up, there are different types of thyristors load sequencing controllers, which are used for many applications. Most common features that abound in these devices are without heat sink, analogue control and heating body. There are many vendors, who offer customized services for varied specifications.
