7.0: Applications (continued)
Voltage Drop Estimation
The following information is for guidance only when planning an installation. Voltage measurements must still be made
to ensure the right working voltage for each Orbit Module.
PSIM-AC PSIM-DC PSIM-5V
PSIM-AC
PSIM-DC
see note 1
volt drop
(from no load output)
V = 5.3 x N (mV)
PSIM-5V
volt drop
V = 2 x N x ( L+1 ) (mV)
Orbit Module with T-CON
volt drop
V = 0.04 x 1+2+3+...+N
see note 2
Standard 2m Comms
cable
see note 3
volt drop
V = 15.2 x N (mV)
Where N = number of Orbit Modules with T-CON following any particular part above
L = cable length for PSIM-5V input cable
Note 1 Input cable length has no affect on this calculation.
Note 2 1 + 2 + 3 + ....... + N = N(N+1)/2.
Note 3 The cable supplied with the Orbit Network Card.
