SMTPA100 is a surge-protective thyristor (Tvs) device that is designed to provide protection to AC (alternating current) voltage lines from spikes and surges. In this article, we will discuss the application field and working principle of the SMTPA100.
Application Field
SMTPA100 is typically used in AC power lines that are exposed to regular power surges, spikes and other abnormal voltage conditions. This device is ideal for use in areas where a large number of electronic devices are connected to the same power line, such as office buildings, industrial complexes, residences, power stations, and other places where power surges are frequent and difficult to control. The device is designed to protect against overvoltage, undervoltage, and open circuit or short circuit conditions.
Working Principle
When an abnormal voltage condition is detected on the connected power line, the SMTPA100 device will send a signal to the thyristor to activate. Once activated, the thyristor will act as a switch and reduce the voltage level to a pre-determined value. This value is adjustable depending on the circumstances, but the typical value is 250 volts. The device will then regulate the voltage and prevent it from exceeding the pre-determined value.
The SMTPA100 is equipped with a noise filter to reduce extra noise that might be present on the power line before the voltage reaches the thyristor. This allows the device to protect against extraordinary voltage spikes and surges that are beyond the pre-determined value.
Conclusion
The SMTPA100 is a surge-protective thyristor device that is designed to provide AC voltage lines with protection from power surges, spikes, and other abnormal voltage conditions. This device is ideal for use in locations where a large number of electronic devices are connected, as it can effectively protect all connected devices from potentially damaging voltage levels. The SMTPA100 regulates the voltage levels and prevents them from exceeding a pre-determined value. Additionally, the device is equipped with a noise filter to reduce extra noise before the voltage reaches the thyristor.
