Hello Joe:

Here are some pictures of a 32 VDC lighting panel, that the owner wanted me to convert to 120 VAC because he was tired of maintaining the batteries.

Instead I built him a power supply from a buckboost transformer, and 4 100 amp diodes on heat sinks.

The system dates from the late 20's.

I find your site to be very informative, and fun.

Thank you.

Trainwire,
