High quality electronic components brand new and original power supply board PB-NHM91-400

Components of the power board
Transformer: used to change the size of the input voltage, converting high-voltage AC into low-voltage AC suitable for equipment, or in some cases converting low-voltage AC into high-voltage AC.
Rectifier: usually composed of components such as diodes, converting AC into DC. Common rectification methods include half-wave rectification, full-wave rectification and bridge rectification.
Capacitor: plays a filtering role, smoothing the rectified DC, reducing voltage fluctuations and ripples, and making the output DC voltage more stable. At the same time, capacitors can also store electrical energy and provide additional energy support when the power supply fluctuates momentarily or the load changes.
Regulator: accurately adjusts and stabilizes the output DC voltage to ensure that the output voltage always remains within the set range when the input voltage changes or the load changes.
Control circuit: responsible for monitoring and controlling the working status of the power board, realizing overvoltage protection, overcurrent protection, overheating protection and other functions to prevent the power board and connected equipment from being damaged due to abnormal conditions.

Functions and effects of power strips
Energy conversion: convert the input AC power into the DC power required by the device, such as converting the 220V AC power of the mains into 5V, 12V, 24V DC power that can be used by electronic devices, or realizing the conversion between different DC voltages.
Stabilize voltage: ensure the stability of the output voltage, reduce voltage fluctuations and interference, provide a stable and reliable power supply for electronic devices, and protect the equipment from damage caused by voltage fluctuations.
Distribute power: distribute the converted power to various components or modules of electronic devices to meet the power needs of different components.
