Application Field

P1806UALRP is a two-terminal AC switch capable of operating in the zero-cross state and can switch from current on to current off as well as current off to current on. The device is suitable for resistive, inductive, and capacitive loads. It is designed to reduce arcing at triggering and limit the need for snubbing circuits.

The device is suitable for use in applications requiring a high level of reliability and low power consumption. It is designed for reducing the power grid demand, while still providing the switching action required for the system. In addition, it is suitable for use in applications with higher power demands.

P1806UALRP can be used in various applications, including: heating, lighting, cooling, wind power generation, photovoltaic power generation, water supply and drainage, switching of consumer electronics, elevator control, machine tools, and robots.

Working Principle

The switching element in the P1806UALRP is a thyristor, which is a type of semiconductor device that has a three-terminal junction. The thyristor can be used as a switch, allowing current to flow through the device when triggered by a small external current, and blocking current when no external current is applied. The device can be triggered to turn on and off depending on the voltage and current conditions, and it is also able to operate in the zero-cross state.

The device is designed with a gate terminal, an anode terminal, and a cathode terminal. When current is applied to the gate, the thyristor will turn on, allowing current to flow through the device. The device will remain on until the gate current is removed, and the device will remain off if the gate current is not applied. When the device turns on, the voltage at the anode terminal is equal to the voltage at the cathode terminal, and the current is proportional to the voltage at the anode terminal.

The P1806UALRP is designed to provide a high degree of reliability and a low power consumption. It uses a low gate voltage of only 1.5V, which allows it to be used in low voltage systems. In addition, the device has a high switching speed, a wide operating temperature range, and a long service life.

Conclusion

The P1806UALRP is a two-terminal AC switch that uses thyristor as the primary switching element. It is designed for a variety of applications, including phase control, rectification, and surge protection. The device is suitable for use in applications requiring a high level of reliability and low power consumption. The device has a low gate voltage and a fast switching speed, which makes it suitable for use in low-voltage systems.
