INPUT SPECIFICATIONS

Frequency: 50 or 60 Hz

INSTALLATION

Current consumption: Approx. 80 mA

• Current Input

Operating temperature: -5 to +55°C (23 to 131°F)

Operating humidity: 30 to 90 %RH (non-condensing)

Mounting: Standard Rack 18BXx or 18KBXx

Weight: 200 g (0.44 lb)

Operational range: 0 – 120 % of rating

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]
