■ DC OUTPUT
• Current Input
Operational range: 0 – 120 % of rating
Overload capacity: 1000 % of rating for 3 sec., 200 % for 10
sec., 120 % continuous
• DC Current: 0 – 20 mA DC and ± 1 mA
Minimum span: 1 mA
Offset: Max. 1.5 times span
Load resistance: Output drive 12 V max.
• DC Voltage: -10 – +12 V DC

■ How To Determine Wattage Range
Calibration Range [W] = (Measuring Wattage) ÷
((VT Ratio) × (CT Ratio))
Check that the required calibration range is within the
available range in the table.
Offset: Max. 1.5 times span
Load resistance: Output drive 1 mA max. at ≥ 0.5 V
■ Pulse output: Frequency output proportional to the input;
0 – 2.777 Hz typical; 0 Hz at 0 W (cutout at approx. 0.5 – 1.0
%); max. 27.77 Hz at 100 % input
[example]
3-phase / 3-wire, measuring wattage 750 kW,
VT 3300 / 110 V, CT 250 / 5 A
(750 × 10 [W]) ÷ ((3300 ÷ 110) × (250 ÷ 5)) = 0 – 500 [W]

Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @ 1 minute

or ground)
ON voltage: ≤ 1 V at 100 mA
• Pulse Unit: refers to how much electrical energy (kWh)
consumption at the primary of the VT and CT corresponds to
the single output pulse per hour from the transducer.
• How to Set Pulse Unit: The switches S1 through S5, VT and
CT ratios, and the transducer's calibration input range all
determine the relative value of one pulse, i.e. the number of
kWh per pulse.
Impulse withstand voltage: 1.2 / 50 μsec., ±5 kV
