COR IBR600 Vehicle Installation Guide
VOLTAGE REGULATION
Most vehicles are designated as either 12 or
24 volt systems, yet even though the battery
is designated as 12 volts the actual voltage at
its terminals during normal vehicle operation is
typically about 13.6 V. However, depending on
its age, state of charge, and electrical load can
typically range between 10 and 16 volts. 24 volt
systems have similar characteristics and can range
between 17 and 32 volts during normal operation.
Depending on model, Cradlepoint routers can
accept an input voltage of 9–18 volts which
means some sort of voltage regulation and
conditioning is generally required.
DC TO DC CONVERTERS
Commercially available DC-DC converters take a
wide voltage range from the battery and provide
a regulated DC voltage output, typically about
13.6 volts. These converters should supply low
ripple voltage, typically less than 250 mV. Higher
quality converters may also provide features such
as reverse polarity protection, isolation, current
limiting, short circuit protection, and overvoltage
protection.
For a 24 volt system a standard regulator that
simply lowers the voltage to 12–14 volts is
acceptable. In a 12 volt system a regulator may
need to either boost the voltage or reduce it.
This dual mode regulator may be somewhat more
expensive but will protect against "brown
out" conditions caused by low input voltage.
It is important that the DC-DC converter can
provide enough power for all devices with some
extra safety margin (reserve power). Do not use
an underpowered converter.
