Power Consumption
The LT-3100 system is powered from 12 VDC or 24 VDC power source. This section will provide power
consumption details for maximum power consumption and typical average power consumption.
Maximum
The LT-3100 system maximum power consumption is listed in Table 8 and in Table 9. The maximum power
consumption is calculated with activity on all interfaces. The LT-3130 Antenna Unit has a built-in heater,
which is activated only when the 24 VDC input power source is available.
The coaxial cable length is an adding factor to the total power consumption of the system. A short coaxial
cable will add approximately ~0 W to the total power consumption. Whereas a coaxial cable with a
maximum length will add ~16 W (24 VDC input) and ~10 W (12 VDC input) to the total power consumption.
The supported coaxial cable lengths for the LT-3100 system are described in LT-3130 Antenna Unit on page
36.
