What type of power should Remote Terminal Units (RTUs) be powered by?

Remote Terminal Units (RTUs) are typically powered by DC power because they are designed to operate efficiently with low voltage and require minimal power consumption. DC power supplies are commonly used in remote monitoring and control applications due to their stability and reliability. This type of power is ideal for the electronic components within RTUs, which need a consistent voltage to function correctly.

AC power, while being utilized in many other electrical applications, can introduce complications such as noise and voltage fluctuations, which are not suitable for the sensitive electronic circuits found in RTUs. Solar energy and wind energy, although renewable, are less consistent and can lead to interruptions in power supply unless equipped with adequate storage solutions, making them less viable choices for the reliable operation of RTUs. In contrast, DC power serves as a strong and effective solution for powering these units in various operational environments.
