Power Supply Capacities and Power Losses
The following table shows the SERVOPACK’s power supply capacities and power losses.
3.1.5
Input Power Supply, Molded-case Circuit Breaker, and Fuse
Use input power supplies that meet the following conditions.
• The main circuit power supply must be a 24-VDC or a 48-VDC power supply.
• The control circuit power supply must be a 24-VDC power supply.
• The main circuit power supply and the control power supply must be two separate input power supplies.
• Power supplies must have double or reinforced insulation that conforms to safety standards.
When choosing molded-case circuit breakers and fuses for input power supplies on the AC side, confirm the
specifications of the input power supplies and refer to this table.
Also, choose molded-case circuit breakers and fuses that meet the following cutoff characteristics.
Cutoff characteristics (25
°
C):
⋅
300% of the rated load input current, five seconds min.
⋅
Does not cut off at the inrush current value of the power supply.
∗1.
Values with instantaneous maximum load.
∗2.
Values with rated load.
