I know a few of you have EC600 power supplies (analog metering) made by EC Apparatus Corp that may not be working.
I have taken some time out to attempt a repair on my unit as schematics have not been available, and the EC600-90 digital metered unit is quite different than the EC600, with only a few minor points of similarity.
In the process I have created a top PCB partial schematic, and a few rough block diagrams.
I now have most features of my unit working again and have acquired a fair knowledge base of the device operation.
Would anyone else here be interested in assisting with continuing the reverse engineering process?
All drawings are being made in Tinycad, and are not yet completed.
I am doing this in tandem with further research into the SM and the Spheric offerings.
It's good to keep the mind active, besides, I like solving puzzles.
Anyone who could actually get hold of a schematic would be a great help, then I could jut concentrate on a troubleshooting flow diagram.
I will post the partial info on my bench, which will be updated as new info comes forth.
Prices on EC600 units are now down to around $100 including shipping, a steal for such a beast of a supply.
