Overview and Specications
Voltage Inputs allow measurement up to 576VAC (Phase to Reference) and 721VAC (Phase to
Phase). This insures proper meter safety when wiring directly to high voltage systems. One unit will
perform to specication on 69 Volt, 120 Volt, 230 Volt, 277 Volt, and 347 Volt power systems.
Higher voltages require the use of potential transformers (PTs).
Current Inputs
The unit supports a 5 amp or a 1 amp secondary for current measurements.
The secondary current must be specied and ordered with the meter.
The PXM 2000 Series Current Inputs use a unique dual input method:
Method 1: CT Pass Through
The CT passes directly through the meter without any physical termination on the meter. This
insures that the meter cannot be a point of failure on the CT circuit. This is preferable for utility
users when sharing relay class CTs. No Burden is added to the secondary CT circuit.
This unit additionally provides ultra-rugged Termination Pass Through Bars that allow CT leads to be
terminated on the meter. This eliminates any possible point of failure at the meter. This is a
preferred technique for insuring that relay class CT integrity is not compromised (the CT will not
open in a fault condition).
