AC Components
The Freedom SW-RVC has the capability of supporting several
AC shore power configurations. Single-line input and dual-line
input configurations. They are described as follows:
AC Input
for Single
AC Line AC input to a single AC line can be supplied from a
single-phase 120 volt 60 Hz AC source such as the
utility grid (power company), a generator, or the
output of a transfer switch.
AC Input
for Dual AC
Lines AC inputs to a dual AC lines can be supplied from a
split-phase or dual-input AC source such as the
utility grid (power company), a generator, or the
output of a transfer switch. The Freedom SW-RVC
can be operated from the following types of 120
volt 60 Hz AC sources:
n
Split
phase:
This source type has two lines, one neutral, and
one ground. The two 120 volts AC lines are 180
degrees out of phase with each other, so that the
two voltages total to 240 volts AC line to line. The
voltage between each line and neutral is still 120
volts AC, and the voltage between the neutral and
ground is approximately zero.
Because the two lines are out of phase, the
currents from each line subtract in the neutral, and
the neutral current will be approximately zero if the
loads are equal. For example, if Line 1 is supplying
20 amps and Line 2 is supplying 15 amps, the
current in the neutral will be 5 amps.
