For equal voltage supplies with volt-per-volt tracking, Rx = 0 ohms.
For other ratios or different voltage supplies, Rx can be calculated by using the
following formulas:
Rx(kohms) = (10/SMR) - 10
SMR(Slave/Master Ratio) = SR(Slave Ratio)/MR(Master Ratio)
where SR = slave desired Vout/rated Vout
MR = master desired Vout/rated Vout
Example:
It is desired to have a slave power supply
rated at 20 VDC and operated at 12 VDC,
while the master power supply rated at 10
VDC is operated at 8 VDC.
The Slave Ratio(SR) = 12V/20V = .60
The Master Ratio (MR) = 8V/10V = .80
Then; The Slave/Master Ratio(SMR) = .60/.80 = .75
And Rx(kohms) = (10/.75) - 10 = 13.33 - 10 = 3.33 kohms.
Note: The slave ratio (SR) must always be less than or
equal to the master ratio (M).
