Power supply
The device comes with a 100-240 V AC, 50-60 Hz full range power supply as standard.
Output voltages power supply | Current load 100-240 V AC power supply max. |
|---|---|
+3.3 V | 12 A |
+5 V | 14 A |
+12 V | 35 A |
+5 V stand by | 3 A |
-12 V | 0.3 A |
-5 V | 0.1 A |
The power supply is connected via the IEC socket (X101) on the rear side of the industrial PC. The assignment includes a protective conductor (1), a neutral conductor (2) and an outer conductor (2).
Fig.8: IEC socketOptionally, you can order the device with a 24 V DC power supply. In this case, the device is supplied with a nominal voltage of 24 V. The power supply and the external wiring are connected via an 8-pin socket (X110).
The main supply voltage is applied between PIN 5 (0 V) and PIN 6 (24 V) of the power supply socket. If the device is equipped with an integrated uninterruptible power supply (UPS), you can also connect an external battery pack to PIN 1 and 2.

|---|---|---|
1 | - BAT | Negative pole of the battery pack |
2 | + BAT | Positive pole of the battery pack |
3 | 24 V UPS | 24 V UPS output 2.5 A, minus is – BAT |

5 | - | 24 V supply voltage, negative pole |
6 | 24 V | 24 V supply voltage, positive pole |
7 | PC-ON | Input PC-ON |
8 | P-S | Power Status output, minus is the negative pole of the supply voltage |
To operate the buffered 24 V output, you must use PIN 1 (-) and PIN 3 (+).
The plug for the power supply is specified for 8 A and can accommodate wire cross-sections of up to 1.5 mm2. For long supply lines, use 1.5 mm2 cables to achieve a low voltage drop on the supply lines. At least 22 V should be present at the power supply plug of the device so that the device remains switched on in the event of voltage fluctuations. The plug is included in the scope of delivery. You can obtain a replacement plug from your Beckhoff Sales using the following ordering option: C9900-P926
