What is activated when the system is in standby and power is applied?

When power is applied to a system that is in standby mode, the micro-cooler circuits are activated as a critical component of many advanced systems that require temperature management. The micro-cooler is essential for regulating the temperature of sensitive electronics or optics in various applications, including surveillance and targeting systems. Activating these circuits upon power application ensures that the system can operate within optimal temperature ranges right from the start, thereby enabling efficient performance and preventing overheating.

In contrast, the other components, such as camera circuits, stabilization systems, and display units, typically come online after the initial cooling has occurred or when the system transitions out of standby, indicating they are not initially activated by direct power application.
