3-3-1 Models and Specifications
NX7-series Power Supply Units
Item Specification
Model NX-PA9001 NX-PD7001
Dimensions 80 × 100 × 100 mm
(W × H × D) 51 × 100 × 100 mm
(W × H × D)
Weight 570 g 290 g
Power supply voltage 100 to 240 VAC (wide-range), 50/60 Hz
(85 to 264 VAC, 47 to 63 Hz) 24 VDC (20.4 to 28.8 VDC)
Power consumption 150 VA max. 85 W max.
Inrush current
*1
*1. The inrush current may vary depending on the operating condition and other conditions. Therefore, select fuses, breakers,
and external power supply devices that have enough margin in characteristic and capacity, considering the condition un-
der which the devices are used.
At 100 VAC:
20 A
*2
/8 ms max. for cold start at room tempera-
ture
At 200 VAC:
40 A
*2
/8 ms max. for cold start at room tempera-
ture
*2. If the ambient temperature is higher or the Controller is hot-started, the inrush current given in the table may be exceeded
by up to twice the given value because the thermistor element with a low-temperature current control characteristic is not
sufficiently cool.
At 24 VDC:
30 A/2 ms max. for cold start at room tempera-
ture
7 A
*3
/3 s max. for cold start at room temperature
*3. Of the inrush current values, the latter value varies depending on the input voltage and may rise to approx. 8.3 A at 20.4
VDC.
Output capacity
*4
*4. Internal components in the Power Supply Unit will deteriorate or be damaged if the Power Supply Unit is used for an ex-
tended period of time exceeding the power supply output capacity or if the outputs are shorted.
