Supplement for Automobile Power
Adapter with Shut Down Timer function
This adapter monitors its input voltage. If the input voltage to the adapter goes above a preset
threshold (
V
on = 12.9VDC*), the adapter will assume that the vehicle engine is running and
will turn on its output.
When the input voltage to the adapter drops below another preset voltage (
V
off = 12.4VDC*),
the adapter will assume that the engine has been turned off and start its shutdown timing
sequence.
The adapter will wait 2 hours* and then shut its output off.
If the input voltage rises above the
V
on threshold during the timing sequence, the adapter will
stop the shutdown sequence and reset its timing.
If the input voltage drops below 10.5VDC*, the output will shut down in about 10 seconds.
When power is rst applied to the unit it will turn on. If
V
in is above the
V
on threshold it will
stay on. If
V
in is less than 10.5V it will shut off in about 10 seconds. If
V
in is higher than 10.5V
but less than
V
on it will go through its shutdown timing sequence.
Note: Removing the input power and then reapplying will turn the unit on again and reset its
timing.
