English to Spanish Tech/Engineering Electronics / Elect Eng MCU main control board

Buenos días,

Espero que puedan ayudarme con la siguiente expresión al español: “MCU main control board”, relacionada con un sistema que incluye procesador de imágenes para endoscopio. Muchas gracias:

“The alternating current supplies power from the AC outlet port to the AC-DC power supply module under the control of the hard switch. When the power is supplied to it, the power supply module would output 24 V voltage and connected to the MCU main control board through wire.

When powering on the device, the MCU will do the self-check, which including the LED status, fan and air pump. If any abnormal found, the touch panel indicator, buzzer and power supply indicator make tips. If malfunction, the touch panel must be locked.”
