INPUT SPECIFICATIONS
Frequency: 50 or 60 Hz
MODEL: 17WT–[1][2]6–R
• Voltage Input
ORDERING INFORMATION
• Code number: 17WT-[1][2]6-R
Specify a code from below for each [1] and [2].
(e.g. 17WT-116-R)
Operational range: 0 – 120 % of rating
Overload capacity: 150 % of rating for 10 sec., 120 %
continuous
• Current Input
• Wattage range (e.g. 0 – 980 W)
Operational range: 0 – 120 % of rating
Overload capacity: 1000 % of rating for 3 sec., 200 % for 10
sec., 120% continuous
■ How to determine Wattage Range
Calibration Range [W] = Measuring Wattage ÷ ((VT Ratio) ×
(CT Ratio))
[1] CONFIGURATION
1: 3-phase / 3-wire
2: Single-phase / 2-wire
3: Single-phase / 3-wire
Check that the required calibration range is within the
available range in the table. Specify this range when
ordering.
[2] INPUT (unbalanced load)
1: 110 V / 5 A AC
[Example]
3-phase / 3-wire, measuring wattage 750 kW,
VT 3300/110 V, CT 250/5 A
2: 110 V / 1 A AC
3: 220 V / 1 A AC
750 × 10 [W] ÷ ((3300÷110) × (250÷5)) = 500 [W]
3
4: 220 V / 5 A AC
A: 100 V / 200 V / 1 A AC (single-phase / 3- wire)
B: 100 V / 200 V / 5 A AC (single-phase / 3- wire)
