Satellite SW voltage specifi cation
1) Rated voltage: 5V
2) Rated voltage: See the next table
3) Chattering period of time: 10ms or less
• Take the fl uctuation in power supply voltage into account (4.75V~5.25V).
4) Range of output voltage
V2=V1Ra/(Rp+Ra) Ra=R1+(1/((1/R8)+(1/R2+…+R7)))
=R1+R8(R2+…+R7)/(R2+…R8)
• Resistance of SRC: MAX 1.0
Ω
• Resistance of BHD harness wire: MAX 0.2
Ω
• Take the fl uctuation in voltage into account (4.75V~5.25V).
• Calculate the range taking the tolerance in resister (±2%) into account to allow the margin in voltage determination
