External Power 6-3
x A 10-gauge (4 mm2) earth ground wire (included in external
power grounding kit, ADS p/n 8000-0434-xx, where xx
represents the required length of the wire) running between the
ExPAC/XBUS/XIO and the monitor
Note: All work required to run AC power to the pole and
wire the power into an approved AC distribution device
(i.e., a disconnect, fuse, or breaker) should be performed
by a licensed electrician. Typically, an electrical permit
from the owner of the collection system or local power
authority is required to install a pole or electrical
equipment next to a monitor location.
DC Power Requirements and Consumption
To run on external power, the TRITON+ system requires a power
source capable of supplying between 9 and 36 volts and a minimum
of 15 watts as measured/available at the ExPAC (not at the power
source output). ADS offers a power supply (ADS p/n 508293) for
this application. However, if you choose not to use this
recommended power supply, the alternate power supply must be a
high-quality industrial-type power supply with ripple no greater
than 250mV P-P. When long cable runs are required, size the
supply and cabling to ensure that line losses do not reduce the net
power available to the ExPAC.
To support TRITON+ monitors running in continuous mode, the
external DC power source must be capable of accommodating the
following system requirements concerning power consumption:
Note: The power to the monitor is ATEX/IECEx I.S.
compliant at 8 to 11.8 VDC.
Following are the power requirements for monitors that
communicate wirelessly and obtain power through an ExPAC:
x Monitor in Sleep Mode with Modem Power On 26 mA
x Monitor in Sleep Mode with Modem Power Off 25 mA
