24 volt to 1.5V, 3V, 4.5V, 6V, 7.5V, 9V, 12V Volt DC/DC Converter
(Adjustable Regulator) |
|
|
These "buck" or reducing converters were designed to power CD players, walkmans, video
games, portable TVs, tape recorders, hand scanners, and radios from automobile cigarette lighter power points.
They are also
useful as OEM regulating power supplies when 6 to 30 volts is available, and a reduction in voltage is required. It is an easy
way to make your equipment mobile. |
Very reliable, inexpensive switchmode, regulated DC/DC
converter adjustable to various voltages. 2 Amp output. |

*Note: Devices using batteries can accept a wide range of input voltages, for example alkalines vary between
1.5 and 1 volt per cell during discharge. This guideline takes this into account. Also most wall-mount adapters are
unregulated. So select the closest to your nominal voltage and don't worry about finding the exact voltage.
**Although
the 12 volt setting requires 14 volts to stay regulated, the 13.6 volts supplied by a car battery even when the car is off will
supply over 11.5 volts, will be adequate for most 12 volt devices.
Advantages:
 Inexpensive switchmode DC/DC converter stabilizes voltage in
automotive applications.
Also can be used to provide regulated voltage in other
applications requiring 1.5 to 12 volt output from 8 to 30 volt input.
Efficiency >50-80%, depending on input, output, and
power. |
