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.
Is this chassis already full or would there be enough space for another FC line? Maybe heat-up play also a role.
Hi, depends on the current and voltage and if the filter chain can be reduced to 2 chokes.Delete
The Design (Optics) looks very 70’s! Schick!ReplyDelete
Are these for sale anywhere.
I build them to order and to given specs. You can email me for details
