I'm a newbie here but was trying to wire a setup and was running into some issues attempting to calculate my required resistance, and resistor tolerance to current.
I have a power supply that brings in a range of voltage, between [60 to 110]VDC @ [ 4.89Amps and approx 510 - 550watts ]
I'm trying to add a [ Shunt Resistor, Voltage Regulator, Voltage Stabilizer, Something?? ] in place to either drop 10 Volts from the power input, or a range where I can adjust the voltage coming in between dropping anywhere from 0 to 10 Volts.
The reason I'm attempting this is because I have a board that requires < 100 VDC to run properly, and I would like the ability to either switch on a regulator/shunt in the route (when necessary).
Voutmax = 100V <- what I've got Vin = 60-110 V. <- What I want
I tried calculating ohm resistance and I believe I wound up with something like, 100K Ohm resistance for a voltage regulator? and something like... 1.03 to 1.1 Ohm resistance on a 100amp shunt resistor?
Honestly really a bit confused still and just trying to find the most direct way to regulate or drop those 10 Volts from my input line.
