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
