Breve descripción
El módulo EPower reemplaza completamente los circuitos de alimentación originales.
Especificaciones
El módulo incorpora tres circuitos de alimentación en uno:
- 12 V @ 0.7 A,
- 5 V @ 1.5 A canal A,
- 5 V @ 1.5 A canal B.
La limitación actual del estabilizador de 5 v está ajustada a 3,7 A [I = 37125 / R1] (la intensidad máxima es de 7 A, si fuese necesario, pero ello podría perjudicar la circuitería del ordenador).
Los valores máximos (limitados por los componentes usados) son:
- 12 V @ 1.0 A,
- 5 V @ 2.5 A por canal (juntos 5A+5B @ 4.5 A).
Esto es mucho mas que el circuito de alimentación original (12 V @ 0.15 A y 2x 5 V @ 1 A).
How to install
The author has made every effort to make the module as reliable and safe to use as possible. However,
You make any modifications inside of your equipment at your own risk !
What you need
- EPower module
- screwdriver
- soldering iron
- tin extractor
- solder tin
- pliers
Enterprise mainboard preparation
