The transducer models are uni-polar 0-10V output which require 24VDC power supplies. So at the moment there is a hand made unit by a non-expert where six transducers with six isolated power supplies are wired and soldered as follows(for ease I only draw three of them):
A 12V 5A SMPS power supply feeds the six boost DC-DC converters. Each DC-DC converter supplies 24V to each transducer.
Here is the DC-DC converters being used.
My questions are:
- The transducer datasheet doesn't say anything about power consumption or max current for the 24V power supply. And the max current the DC-DC converter can supply is given as 50mA:
Is there a way to determine whether
this current is enough per traducer? The units work at the moment
but I'm not sure if it is properly sized.
2. In the datasheet of the DC-DC converter an LC filter is
recommended at the input:
Should such a filter be inserted in front of each DC-DC converter input or is it enough to use only one as in the drawing here?
