2.6 Operating Voltages and Cable Lengths

The NGC is designed for connection to a 12 VDC or 24 VDC power source. The
12 volt power source must provide a minimum of 10.5 VDC to a maximum of 16
VDC at 4 amps minimum, and the 24 volt must provide a minimum of 21 VDC to a
maximum of 28 VDC at 2.2 amps. The configurations with the auxiliary feed-
through heater increase the requirements.
Adequate wire size is a function of the distance between the NGC and the DC
power supply. When running wiring from the power source to the NGC,
consideration must be given to the voltage dropped between the power source
and the NGC. Smaller wire gauges have greater resistance and, therefore, a
greater voltage drop across the wiring. The following tables (see
Table
lengths for DC and AC installations with and without the auxiliary feed-through
assembly heater.
Additional devices connected to the NGC and requiring power (XMVs, radios, etc.)
must be factored into this calculation. Refer to their technical specifications for the
requirements of each, or call Totalflow for help computing cable requirements for
additional loads.
