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.
