Allowable wiring resistance:

100 Ω or less

Effect of wiring resistance:

NDIS 50 ppm of rdg. / Ω (when using remote sensing wire)

Does not compensate for clamp wiring resistance. Depends on
the gauge resistance.

Allowable input voltage:

±10 VDC (between H-L) continuous

Allowable common-mode voltage: Channel-to-channel: 30 VACrms

Between input and ground: 250 VACrms (-B12, -B35), 30 VACrms
(-NDI)

However, NDIS connector shell is connected to earth potential.

Common mode rejection ratio

*

:

When the integration time is 16.67 ms or more: 120 dB or more.

When the integration time is 1.67 ms: 80 dB or more

(voltage conversion value at 50/60 Hz ±0.1%, bridge voltage of 2 V)

Normal mode rejection ratio:

For integral time of 16.67 ms or more: 40 dB or more (50/60 Hz ±
0.1%)

For integral time of 1.67: 50/60 Hz is not rejected.

(voltage conversion value given a bridge voltage of 2 V)

Insulation resistance

*

: Between input and earth

20 MΩ or more (500 VDC)

Withstand voltage

*

: Between input and earth

2300 VAC for one minute

Channel-to-channel: 30 VACrms or less

Power consumption: Approx. 3 W (one module)
Weight:

Approx. 0.5kg.

External dimensions: Approx. 57 (W) × 131 (H) × 151 (D) mm (including the terminal

cover)

Terminal type:

-B12, -B35: Clamp, terminal board is detachable

-NDI: NDIS, detachable by channel

Applicable wire size: 0.14 to 1.5 mm

(AWG26 to 16) (excluding -NDI)

* Does not apply to the NDIS terminal.

Effects of Operating Conditions

The specifications below apply when the integration time is 16.67 ms or more.
Warm-up time:

At least 30 minutes after power-up

Effects of ambient temperature:

The effect received by changes in 10°C increments of the ambient
temperature is

±(0.1% of range) or less

Effects of power fluctuation:

Meets the accuracy specifications for AC power supply in the
range 90 to 132 V and 180 to 250 V

Effects of magnetic field:

The fluctuation in external magnetic fields for AC (50/60 Hz) 400
A/m is ±2% of range or less

Effect of position:

Horizontal with the feet at the bottom is the rule.
