Input voltage range V 1-phase, AC180 ～ 253V
Power capacity kVA 0.5
Does not include rush current
Note2)
Note3)
Note2) The power capacity (0.5kVA) is the rating value for normal operation. The power capacity does not include the rush
current when the power is turned ON. The power capacity is a guideline and the actual operation is affected by the
input power voltage. The power consumption in the specific operation pattern with the RV-2SQ is approx. 0.33kW.The
short circuit breaker should use the following.
*Operate by the current leakage under the commercial frequency domain (50-60Hz). If sensitive to the high
frequency ingredient, it will become the cause in which below the maximum leak current value carries out
the trip.
Note3)If the earth leakage breaker is installed in the primary side power supply circuit of the drive unit, please select the earth
leakage breaker of the specification of the amperage rating 10A and 10mA of sensed current. (The leak current of the
controller is set to about 7.5mA)
