Input voltage of 24 VDC
Note 1. The rated input current of the SERVOPACK is the nominal value at the rated load.
Select the appropriate capacity in accordance with the specified derating.
Cutoff characteristics (25°C): 300% five seconds min.
2. To comply with the low voltage directive, connect a fuse to the input side. Select the fuse or molded-case circuit
breaker for the input side from among models that are compliant with UL standards.
The table above also provides the nominal values of current capacity and inrush current. Select a fuse and a
molded-case circuit breaker which meet the cutoff characteristics shown below.
• Main circuit, control circuit: No breaking at three-times the current values of the table for 5 s.
• Inrush current: No breaking at the same current values of the table for 20 ms.
