■ Input Range

• AC: Operational voltage range: rating ±10 %,

50/60 ±2 Hz, approx. 2 VA

How To Determine Var Range:

Calibration Range [var] = Measuring Range ÷ ((VT Ratio) ×

(CT Ratio))

• DC: Operational voltage range: rating ±10 %,

or 85 – 150 V for 110 V rating, ripple 10 %p-p max.,

approx. 2 W (18 mA at 110 V)

Check that the required calibration range is within the

available range in the table. Specify this range when

ordering.

Operating temperature: -5 to +60°C (23 to 140°F)

Operating humidity: 30 to 85 %RH (non-condensing)

Mounting: Surface or DIN rail
