DESCRIPTION
The PowerTrak Series Power Monitoring Interface moni-
tors numerous power system parameters for local display
and/or remote connection to a BAS or other data acquisition
equipment. Any three-phase or single-phase 50/60 Hertz elec-
trical system from 120 to 600 volts can be monitored by the
PowerTrak without the need for potential transformers. Higher
voltage systems such as 5 kVolt or 15 kVolt services can also
be monitored using potential transformers. The PowerTrak is
available for use with 1 amp, 5 amp or 0.333 volt current trans-
formers. Options include a current transformer shorting
assembly and a digital LCD display.
Furnished in a NEMA 1 hinged cover enclosure with external
mounting feet and conduit knockouts on all sides, the
PowerTrak is simple to install. Setup of the PowerTrak is eas-
ily accomplished with a selector switch and DIP switches. A
truly unique feature of the PowerTrak is its ability to identify
and electronically correct wiring problems such as reversed
CT polarities or improper phasing of voltages with CT's.
