1. The AC and DC values above are given for a cold start, and the AC values are at room temperature. The AC inrush control circuit uses a
thermistor element with a low-temperature current control characteristic. If the ambient temperature is high or the Controller is hot-started, the
thermistor will not be sufficiently cool, and the inrush current given in the table may be exceeded by up to twice the given value. The DC inrush
control circuit uses a capacitor-charging delay circuit. If the power is OFF for only a short time for a hot-start, the capacitor will not sufficiently
discharge and the inrush current given in the table may be exceeded by up to twice the given value. An inrush current of approximately 4 A
may occur and continue for 1 s when the power is turned ON. When selecting fuses, breakers, and external DC power supply devices for
external circuits, allow sufficient margin in shut-off performance.
*
2. Internal components in the Power Supply Unit will deteriorate or be damaged if the Power Supply Unit is used for an extended period of time
exceeding the power supply output capacity or if the outputs are shorted.
*
3. Supported only when mounted to CPU Rack.
*
4. The tests can also be performed with the LG terminal and GR terminal connected to each other.
*
5. Change the applied voltage gradually using the adjuster on the Tester. If the full dielectric strength voltage is applied or turned OFF using the
switch on the Tester, the generated impulse voltage may damage the Power Supply Unit.

Precautions for Use

Please make sure to use NJ-PA3001/NJ-PD3001 for all products including NJ-series CPU rack and expansion rack.
Power Supply Units Current Consumption
Checking Current Consumption and Power Consumption
After selecting a Power Supply Unit based on considerations such as the power supply voltage, calculate the current and power requirements for
each Rack.
Condition 1: Current Requirements
There are two voltage groups for internal power consumption: 5 V and 24 V.
Current consumption at 5 V (internal logic power supply)
Current consumption at 24 V (relay driving power supply)
Condition 2: Power Requirements
For each Rack, the upper limits are determined for the current and power that can be provided to the mounted Units. Design the system so that
the total current consumption for all the mounted Units does not exceed the maximum total power or the maximum current supplied for the voltage
groups shown in the following tables.
The maximum current and total power supplied for CPU Racks and Expansion Racks according to the Power Supply Unit model are shown below.
Note: 1. For CPU Racks, include the CPU Unit current and power consumption in the calculations. When expanding, also include the current and
power consumption of the I/O Control Unit in the calculations.
2. For Expansion Racks, include the I/O Interface Unit current and power consumption in the calculations.

Using the Sysmac Studio to Display Current Consumption and Width
CPU Rack and Expansion Rack current consumption and width can be displayed by selecting CPU/Expansion Racks from the Configurations
and Setup in the Multiview Explorer. If the capacity of the Power Supply Unit is exceeded, an error icon is displayed in the power supply unit of a
corresponding rack. For details, refer to Sysmac Studio Operation manual (W504).
