Transfomer Question

[Dragonten]

I am removing a Datamarine depth finder and speedometer. They get power from a 32volt transformer from what I can tell. There is 12volts at the units. Just curious if I could just hook up a Simrad Chartplotter to that same power source? Are there any other considerations when connecting to transformer?

Check the power rating of the step Down converter and make sure it s big enough for the new plotter. New electronics have become very efficient so chances are it is.

Put in a modern dc to dc converter. They have come a long way in the last 30 or 40 years.

I replaced a big old newmar with a victron of larger output and smaller size for less than 20 percent of the cost of the old one.

Transformer or DC to DCv converter?
There should be a model number or Amp rating on it.
New equipment is more efficient but sounders and radios still need power.
