MOBILE MODELS
These units differ from the consumer types on this page only in that on these Mobile models the output voltage is fixed at 13.8 volts
This suits those appliances which are sold and intended for Mobile Operation, and therefore expect to operate at or around 13.8 volts, the average voltage level when a vehicle engine or charging system is running. Such appliances can be quite voltage sensitive, to lower voltages in particular.
Good examples are Amateur (Ham) VHF and UHF rigs, where transmit RF power can drop off rapidly if the applied battery voltage drops.
The SR138120 (see further down) will accept a 6 volt input. Perfect for running a modern radio in a 6v Vintage or Veteran Car

When a (nominal) 12v lead acid battery drops below 12.2 volts or so, there is still useable energy available, even though the connected radio may reduce output power. The Buck-Boost converter will elevate the low voltage to the required or expected 13.8, restoring full power operation. Please note the unit does not ‘create’ energy, and it is not 100% efficient.
Therefore, more volts means slightly less ampere-hours available from the battery at the time, but of course without the boost converter to raise the voltage to a suitable working level, the available ampere hours (current) is not available to be used!!

12 VOLT BUCK BOOST REGULATORS/CONVERTERS
These clever devices provide a stable fixed voltage output from your unstable varying voltage input.
Unlike simple 24-12 volt Regulators, with these units your Input Voltage can be above OR below the Output Voltage

CONSUMER TYPE
USE FOR ‘HOME’ TYPE APPLIANCES, SUCH AS TV, DVD PLAYER, LED LIGHTS
In general, for those 12 volt appliances which are not specifically designed or sold for operation or use in a vehicle or other mobile environment, but which do in fact operate from a stable 12 volt supply derived from a mains voltage ‘plugpack’ (wallwart) supply.
All these Regulators have complete isolation between Input and Output and between Input, Output and the Frame of the device

MOBILE TYPE
USE FOR ‘VEHICLE’ TYPE APPLIANCES, SUCH AS CAR STEREO, RADIO TELEPHONE, ‘PHONE CHARGER, GPS
In general, for those 12 volt appliances specifically designed for use in a vehicle or other mobile environment, and as such can operate at the higher 13.8 voltage, and in fact will often perform at their I best only when the supplied voltage is at 13.8 volts
All these Regulators have complete isolation between Input and Output and between Input, Output and the Frame of the device
