- ***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.

## **LG** 

Ground to a resistance of 100 Ω or less to increase noise resistance and avoid electric shock. 

## **GR** 

Ground to a resistance of 100 Ω or less to avoid electric shock. 

## **RUN Output** 

The internal contacts for the RUN output turn ON when the CPU Unit is in RUN status.

## **Precautions for Use** 

## **Compatible CPU Models** 

NJ-PA3001/NJ-PD3001 are dedicated for NJ-series. 

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. 

|**Power**<br>**Supply**<br>**Units**|**Max. current supplied**|**Max. current supplied**|**Max. current supplied**|**(C)**<br>**Max. total**<br>**power**<br>**supplied**|
|---|---|---|---|---|
||**(A) 5-VDC CPU**<br>**Racks***|**(A)5-VDC**<br>**Expansion**<br>**Rack**|**(B) 24 VDC**||
|**NJ-PA3001**|6.0 A|6.0 A|1.0 A|30 W|
|**NJ-PD3001**|6.0 A|6.0 A|1.0 A|30 W|



Conditions 1 and 2 below must be satisfied. 

Condition 1: Maximum Current 

- (1) Total Unit current consumption at 5 V ≤ (A) value 

- (2) Total Unit current consumption at 24 V ≤ (B) value 

- Condition 2: Maximum Power 

- (1) × 5 V + (2) × 24 V ≤ (C) value 

> ***** Including supply to the CPU Unit.

## **Example: Calculating Total Current and Power Consumption** 

Example: When the Following Units are Mounted to a NJ-Series CPU Rack Using a NJ-PA3001 Power Supply Unit 

|**Unit type**|**Model**|**Quantity**|**Voltage group**|**Voltage group**|
|---|---|---|---|---|
||||**5 V**|**24 V**|
|CPU Unit|NJ501-1500|1|1.90 A|-|
|I/O Control Unit|CJ1W-IC101|1|0.02 A|-|
|Basic I/O Units (Input Units)|CJ1W-ID211|2|0.08 A|-|
||CJ1W-ID231|2|0.09 A|-|
|Basic I/O Units (Output Units)|CJ1W-OC201|2|0.09 A|0.048 A|
|Special I/O Unit|CJ1W-DA041|1|0.12 A|-|
|CPU Bus Unit|CJ1W-SCU22|1|0.28 A|-|
|Current consumption|Total||1.9 A+0.02 A+0.08 A ×<br>2+0.09 A × 2+0.09 A ×<br>2+0.12 A+0.28|0.048 A × 2|
||Result||2.84 A (≤6.0 A)|0.096 A (≤1.0 A)|
|Power consumption|Total||2.84 × 5 V = 14.2 W|0.096 A × 24 V = 2.3 W|
||Result||14.2 W + 2.3 W = 16.5 W (≤30 W)||



## **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).
