Protective features and error states
In an error state, the red error LED will illuminate. All error indications will clear themselves once the
error is cleared.
Current limit:
The DNA 12 will shut down temporarily if the output current rises above 3.5 amps. This also
protects the unit from damage if the atomizer shorts out.
Low battery:
To prevent battery damage, the DNA 12 will shut off if the battery voltage dips below 3.1 volts
(loaded) for more than .25 seconds.
Overvoltage:
In the event an atomizer of too high resistance to allow the desired power setting is attached,
the output voltage will be limited to 6.0 volts.
Overheat:
DNA 12 has a temperature sensor onboard. If the board temperature rises above 80C, the error
light will illuminate and the output will remain off until the board temperature drops.
High resistance:
If the DNA 12 senses an output resistance of more than 10 ohms, it will assume there is no
atomizer connected and remain in a low power sleep state.
