Power supply

In its basic configuration, the industrial PC is equipped with a 100-240 V AC, 50-60 Hz full-range power supply unit.

Current carrying capacity power supply unit
Output voltages power supply unit	Current load 100-240 V AC power supply unit max.
+3.3 V	21 A
+5 V	15 A
+12 V1	11 A
+12 V2	8 A
-12 V	0.3 A
+5 V stand by	2.5 A

The power supply is connected via the IEC socket (X101) on the top of the industrial PC. The assignment includes a protective conductor (1), a neutral conductor (2) and an outer conductor (2) (see Fig. 3).

Power supply 1: — Voltage socket 100-240 V

Optionally, you can order the industrial PC with a 24 V DC power supply unit. In this case, the industrial PC is supplied with a nominal voltage of 24 V. A 5-pin socket is used for the connection of the power supply (X101) as well as the external wiring (X102) of the industrial PC.

The main supply voltage is applied between PIN 1 (24 V) and PIN 2 (0 V) of the voltage socket (X101). If the industrial PC is equipped with an integrated uninterruptible power supply (UPS), you can also connect an external battery pack to PIN 4 and 5.

Power supply 2: — Voltage socket pin numbering

Voltage socket (X101) pin assignment
Pin	Signal	Description
1	+24 V	24 V supply voltage, positive pole
2	-	24 V supply voltage, negative pole
3		Protective earth
4	+BAT	Positive pole of the battery pack
5	-BAT	Negative pole of the battery pack

The positive pole of the supply voltage at PIN 1 of the voltage socket (X101) is looped through to PIN 5 of the socket (X102). PIN 5 thus serves as the positive pole for PC-ON.

Power supply 4: — Socket external wiring pin numbering

Socket external wiring (X102) pin assignment
Pin	Signal	Description
1	-24 V UPS	Negative pole UPS output
2	+24 V UPS	24 V UPS output 2.5 A
3	P-S	Output power status, minus is the negative pole of the power supply (X101)
4	PC-ON	Input PC-ON
5	+24 V	Supply voltage and positive pole for PC-ON
