Charging from an External DC Voltage Supply
Similarly, the instrument may have its internal battery charged from an
external DC voltage supply of between 10V and 15V, with at least 1.5A of
drive capability. If this is desired, obtain a DC power jack, which meets the
requirements of 2.5mm pin diameter and 5.5mm external diameter. For
example: Switchcraft® 760. The center pin connector should be a positive
potential connection, note that internal circuitry prevents damage from
polarity reversal.
The DC power supply used may be any laboratory type of power supply or
alternatively a 12V lead-acid battery (e.g., an automobile battery). This latter
method for recharging the internal battery in the instrument yields the useful
feature of allowing you to recharge the instrument from an automobile (e.g.,
the cigarette lighter), thus you may take the instrument into remote locations
(or locations where the local AC supply is unknown) without the concern of
recharging the internal battery.
Continuous Power from External Supply
Both the charging module or an external DC supply may be left continuously
applied without damage to the 2000 instrument. Xitron Technologies
recommends using an external DC supply for process control applications.
Warning:
Unless the charging source is an external battery, continuous
operation from an external supply when the instrument is connected to a
process control system may degrade the safety of that system.
