12V to 12V regulator DC/DC converter with wide input range. Designed to keep electronics alive during engine cranking.

More 12V iinput DC/DC converters with 12VDC input and 1.5 V to 48V output

These are fully regulated switchmode power converters, designed to allow the use of sensitive 12 volt equipment in 12V vehicles. These are attractive, reliable, robust DC/DC converters good for fork lifts, off-road, military, construction and recreational equipment. They are typically used for military equipment, PLCs, laser scanners, and wherever rugged 12VDC is required. They are ultra quiet, both in the input and noise fed back into the input.

To determine the amperage you need just add up the watts of all the equipment and divide by 12 volts.
These converters are fully isolated, so can be used in any configurations.

*Low input voltage behavior. When the input falls below 11 volts the output voltage is no longer regulated, but will fall in voltage. At 1 amp output this drop-off starts when the input voltage is 8.3V.
The unit will turn itself off at about 7 volts, and will automatically turn back on again when the input voltage is restored.

Heavy Duty High Current Switchmode DC/DC Converters.

High efficiency.

Excellent line and load regulation.

Wide input voltage range suitable for 12 volt automotive and vehicle systems immune to engine starting voltage sags.
