■ 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

3-phase / 3-wire, measuring range 75 kvar, VT 220 / 110 V,
CT 250 / 5 A
Weight: 400 g (0.88 lb)
