I have located some universal digital display panel meters that I would like to use for a DC power plant voltage/amperage monitor system.
The meters have an internal regulator for the power supply and state they will need an input of DC 5 to 18 volts. (No current specified, but I assume it is not too great)
The DC system I want to use them on has a nominal operating voltage range of from 45 to 60 Volts DC.
To keep things simple, I would like to employ dropping resistors off the DC plant to supply the operating voltage for the meters. Can someone help me with the resistor values calculations to do this?
Is there a better simple way?
Thanks in advance.
