The Microcomputer Protection Power Supply Module typically consists of a rectifier, filter, voltage regulator, and protection circuits. The rectifier converts AC input to DC, which is then filtered to remove noise and fluctuations. The voltage regulator ensures the output remains stable regardless of input variations. The module also includes protection features such as overload, short-circuit, and over-voltage protection. These safeguards prevent damage to both the module and the connected protection relay. The working principle revolves around maintaining a constant and clean power supply to the microcomputer, enabling accurate and timely fault detection and isolation.
