Overload capacity: 1000 % of rating for 3 sec., 200 % for 10
sec., 120 % continuous
• Voltage Input
Operational range: 0 – 120 % of rating
Overload capacity: 150 % of rating for 10 sec., 120 %
continuous
PERFORMANCE in percentage of span
Accuracy: ±0.5 %
Temp. coefficient: ±0.05 %/°C (±0.03 %/°F)
Response time: ≤ 1 sec. (0 – 90 %)
■ How To Determine Wattage Range
Calibration Range [W] = Measuring Wattage ÷ ((VT Ratio) ×
(CT Ratio))
Ripple: 0.5 %p-p max. (50/60 Hz)
Line voltage effect: ±0.1 % over voltage range
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @ 1 minute
(voltage input to current input to output 1 or output 2 or
power)
Check that the required calibration range is within the
available range in the table. Specify this range when
ordering.
[example]
3-phase / 3-wire, measuring wattage 750 kW,
VT 3300/110 V, CT 250/5 A
500 V AC @ 1 minute (output 1 to output 2 to power)
2000 V AC @ 1 minute (input or output or power to ground)
750 × 10 [W] ÷ ((3300÷110) × (250÷5))= 0 – 500 [W]
