  1. The coil resistance is measured at a coil temperature of 25℃ and 35%-70% of humidity.
  2. The operating parameter is measured at a coil temperature of 25℃ indicated in the percentage of the rated voltages.
  3. The coil rated current is measured as the real current consumption under the rated voltages.
