Having dumped the massive 3-phase transformer, I needed another source of power for the drives.
A nice SMPS would have been an acceptable solution but I don't have one and didn't fancy coughing up hundreds of £ for one. So I took a 110V CTE (centre tapped earth) site transformer and removed some secondary turns to leave a 100V secondary. This will give me around 140Vdc off load. The "Wall mounted" version is not potted, so easy to dismantle and modify, unlike the yellow moulded site transformers with their potted internals.
