Maximum Momentary Output of 17A
While the rated output current is 8.5A, maximum momentary output current of up to 17A is supported. This lets you select an appropriate power-supply capacity based on the total rated current of actuators, without having to consider the maximum momentary current that may be generated by the actuator during acceleration.
Because you no longer need to use an expensive high-capacity power supply, cost can be reduced substantially.
* The maximum momentary output current must be considered if the actuator operating conditions are tight. For details, refer to “Selection Guide” on the right.
Supporting Parallel Operation
Load Detection Function
Selection Guide: Number of Actuators Connected
When selecting a power-supply unit for operating multiple actuators, normally a unit with a capacity equal to or exceeding the total maximum current of all actuators is chosen. However, actuators generate their maximum current only momentarily during acceleration, etc., and in many cases the power-supply is over-specified. On the other hand, the PS-24 power supply provides the following advantages:
Number of Power-supply Units
Basically, how many power-supply units you need should be determined in such a way that the total rated current of all actuators will remain within the rated current of the PS-24.
