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 circuity of the computer).
Maximum values (limited by used components) are:
- 12 V @ 1.0 A,
- 5 V @ 2.3 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
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
The following components should be desoldered from the motherboard:
