3OP2, 3OP3, 3DIR2
Vmax × Imax × 2, W
Nominal frequency 25, 50
or 60 Hz
100 Hz Fmax
Nominal frequency 400Hz 500 Hz
Data Units – Low Resolution Option
U1 1V
U2 1A
U3 1kW/kvar/kVA
Data Units – High Resolution Option
PT Ratio = 1 0.1V U1
PT Ratio > 1 1V
U2 0.01A
PT Ratio = 1 1W/Var/VA U3
PT Ratio > 1 1kW/kvar/kVA
See Device Options Setup for information on the device resolution option.
1
CT Ratio = CT primary current/CT secondary current
2
The default Voltage scale is 144V (120V +20%). You can change it via the Device Options setup in PAS.
3
The default Current scale is 2 × CT secondary current (2.0A with 1A secondaries, 10.A with 5A secondaries). You can change
it via the Device Options setup in PAS.
4
Pmax is rounded to whole kilowatts. With PT=1.0, if Pmax is greater than 9,999,000 W, it is truncated to 9,999,000 W.
