PSIM-AC PSIM-DCPSIM-5V

The PSIM-5V is powering the whole Orbit Network. PSIM-5V volt drop is calculated using 12 as the total number of Orbit modules; the RS232IM is included in this number.

Total Voltage drop = PSIM-5V + modules (6 off) + Cable 1 + Modules (6 off)

=(2 x 12 x [3+1]) + 0.04 (1+2+3+4+5+6+7+8+9+10+11+12)+ (15.2 x 6) + 0.04 (1+2+3+4+5+6)

=96 + 3.12 + 91.2 + 0.84

=191 mV

Then approximate voltage at end of network

=

nominal supply voltage - calculated volt drop

 

=

5.25

- 0.191

 

= 5.06

V

i.e. greater than 4.75 Vdc the minimum working voltage. In this example the input supply to the PSIM-5V could be reduced to 5.1 V (the Orbit nominal value).
