A guide on how to make the, ACBEL FSA021 IBM 39Y7228, server power supply run outside of its server enclosure.

This video also goes through how I generally reverse-engineer power supply interfaces of server power supplies.

To reverse-engineer a power supply interface by trial-and-error, finding the GND pads and connecting them to other pads through a 1K or 10K resistor is a safe way to probe for possible start up conditions.

Test and teardown of a Eaton 9355 UPS (formerly the Powerware 9355). It is a three-phase, double-conversion online UPS. Output power ranges from 10-15 kVA in a changeover scenario as follows: 150% for 5 sec / 125% for 1 min (online), 110% for 10 min. Battery type is 9 Ah, sealed, lead-acid, maintenance-free. Battery charger is default 3.4A per battery string. Charger current is configurable from 0.5A to 25A per string with an overall maximum of 34A (limited by input current)

This Sedecal SHF-330, with HF meaning High Frequency, was originally a 37.5 kW x-ray high voltage generator. It later received an upgrade, to a Sedecal SHF-530, which is a 50 kW 500mA x-ray high voltage generator.

Teardown of a Sirio 10000P solar inverter designed in Italy and made in Taiwan. A extremely heavy and well built power house. Full of TO-264 sized IGBTs and a giant single PCB layout for the inverters.

It has been a while, so there is 4 videos that I forgot to update this thread with.  :-DMM
