Specifications.
Current Input
Pick up current 0.3A rms
Max reported current
FD / JG
250A rms
KD / LD 630A rms
Accuracy 0.5% of reading
Voltage Inputs
Range
Line-to-neutral
30 - 366 Vac
Line-to-line 52 - 635 Vac
Supported Systems 3 element wye, 3 element wye + neutral
2 element delta, 4-wire delta systems
Input Impedance 996 kilo ohm/phase
Burden per phase 0.36 VA/phase max. at 600 V;
0.014 VA at 120 Volts"
Phase Voltage Connections Internal via screw terminal to busbar
Neutral Connection For wye system, a Neutral is required to be connected
to the PM3 on the right Phoenix connector.
If Neutral is not available, the meter will calculate
a virtual Neutral based on the phase to phase RMS
voltage. The system voltage must be balanced for this
to be accurate.
