.These are regulated switching power
converters (switchmode), designed to allow the use of 12 volt equipment in 24
volt vehicles. This is a modification of our popular PST-D24/12-100 and
PST-D24/12-150 by adding male and female cigarette lighter adapters to make it
more convenient for pilots, truck drivers, fork lift drivers, heavy equipment
operators and soldiers to use 12 volt equipment in 24 to 28 volt vehicles and
airplanes. To determine the amperage you would need add up the watts of all
the equipment and divide by 13.8 volts. These DC/DC converters are available
for retail, commercial, and wholesale sales, and can be custom modified to put
out other voltages.
These are also known as 24 volt voltage reducers,
and voltage regulators. These DC/DC voltage reducing converters are suitable
for running electronics, such as radios, CD players, computers, and CB radios.
They are NOT usually suitable for headlights, motors, solenoids, or other
electromechanical devices unless they are protected from inductive kickback and
motor noise, and the current is rated for the inrush, stall, or locked rotor
current of the load.
These DC to DC converters also
come in higher powers and in permanent installation configurations.
