Just finished a new field coil supply.
This time in landscape style.
Compared to my previous FC PSUs which were in portrait style, this one contains a single power supply only. It is meant to power two field coils in series.
The output is ecntered at 20V / 2A and can be adjusted in 9 steps of roughly 5%
Above the setting with 5% below center. Next 5% above.
Adjustment is in discrete steps via the two switch banks which select different taps of the power transformer. The supply is purely passive with 3 chokes in a LCLCL arrangement for very cleanly filtered output.
Above a setting close to maximum.
A Feld coil supply for purists who prefer no solid state regulation yet very clean and adjustable output.
