Avoid mounting the device near a spot subject to extreme heat, such as
engine room or exposed to direct sunlight.
Stable Power supply
Consider below two types of voltage supply problems in a vehicle for
stable power supply.
Brown-out voltage problem
The spark plug would draw significant stream of instantaneous
electrical power from the car battery when starting the engine.
Therefore the voltage supplied to other electrical equipment drops
significantly lower than its normal level.
Transient voltage problem
(sometimes called spikes)
The significantly changed positive or negative voltage may be
caused by interference from the electrical-mechanical components
in the vehicle, or even from additional electrical equipment
connected to the vehicle’s electrical power system. Without
treatment, sharp spikes are a potential threat to K530S as well as
other electrical equipment on the vehicle.
To protect device and prevent the undesirable voltage transients or
brown-
outs, it’s required to regulate input voltage before feeding it to the
power input of device.
There are two ways of electrical voltage regulation. One way is to
