POTENTIAL RANGE (Any One) 110V or 440V
B. DOUBLE ELEMENT FOR 3 PHASE 3 WIRE LOAD: MODEL - DPF3
CURRENT RANGE (Any One) 0.5/1A, 1/2A, 2.5/5A, 5/10A, 10/20A
POTENTIAL RANGE (Any One) 62.5/125V, 110/440V, 125/250V, 250/500V, 300/600V

Rated Accuracy: ± 1.0% of full scale value as per ISS 1248/84 between 10% to 100% of the scale for Single Phase UPF Wattmeters.
  ± 1.5% of full scale value as per ISS 1248/84 for Three Phase Wattmeters.
  ± 1.5% of full scale value as per ISS 1248/84 for 0.2 P.F. (LPF) Single Phase Wattmeters.
Note:

All Wattmeters are calibrated at cosø = 1 and Varmeters at sinø = 1.

  All Low Power Factor Wattmeters are calibrated at cosø = 0.2 Lag.
  Other Voltage and Current ranges can be supplied on request, subject to technical feasibility.
