Power Specifications
The supply voltage for the Multi Pulse Counter should be between 3.5
–
5 V
DC
. A 5 V
DC
(up to 1A) adapter
is provided with the package, however, a similarly rated adapter can be used for supplying power if need
be. There is provision for a non-rechargeable battery to supply power to the device during a power
outage to ensure uninterrupted operation, more information in the following section.
Battery Specifications
A non-rechargeable Lithium Thionyl Chloride Battery is provided with the device for back up during an
outage. The C-size battery is rated at 9000 mAH with an output of 3.6V. The Multi Pulse Counter can run
upto 30 days on battery backup in an idle state. When the Multi Pulse Counter is running on battery it
will continue to count pulses until the battery dies. While running on battery, we estimate the device
can countto 1 million pulses before it runs out of charge. The actual battery backup time may vary
depending on the input pulse frequency and the remaining charge on the battery. Once the battery is
completely drained, the user will receive an alert on the LCD once the device is powered on. The battery
can be easily replaced by removing the drained battery replacing it with a new one.
Enclosure Specifications
Global Power Product’s
Multi Pulse Counter is enclosed in a reliable, weatherproof NEMA 4x-rated
enclosure as shown in figure 1. The dimensions of the enclosure are 10.6 x 8 x 3.3 in. The NEMA-rated
enclosure works both indoors and outdoorsby protecting against foreign objects like dust and the
damaging effects of water. The enclosure will be undamaged by the external formation of ice. However,
the opening at the bottom of the enclosure must be sealed by the user to retain the waterproof ability
when in use.
