PSIM-AC PSIM-DC PSIM-5V

Application 1: Basic Small Network Connection.

•Power supplied to network from PC via network card, no PSIM used.

•Modules connected using standard communication cables.

Volt drop total in mV	=	cable 1 + module (3 off) + cable 2 + module (3 off)
	= (15.2 x 6) + 0.04(6+5+4+3+2+1) + (15.2 x 3) + 0.04(3+2+1)
	=	138 mV
Then approximate voltage at end of network	=	nominal supply voltage - calculated volt drop
	=	5.1 - 0.138
	=	4.96 V
