EPower module (top view)

Brief information

The EPower module replaces the original Enterprise power circuits.

Specification

The module has three power sources:

  • 12 V @ 0.7 A,
  • 5 V @ 1.5 A channel A,
  • 5 V @ 1.5 A channel B.

The current limitation of the 5 V stabilizer is set at 3.7 A [I = 37125 / R1] (the maximum possible current is 7 A, if need, but it could damage the circuitry of the computer).

Maximum values (limited by permissible current of the power filters) are:

  • 12 V @ 1.2 A,
  • 5 V @ 2.5 A per channel (both 5A+5B @ 4.5[A]).

This is much more than the original power source (12[V] @ 0.15[A] and 2x 5[V] @ 1[A]).

How to install

What you need

  • EPower module
  • screwdriver
  • soldering iron
  • tin extractor
  • solder tin
  • pliers
