•  Power consumption: 120 W @ 24 VDC (Approximately)
If you want to use the computer on AC power you need a power supply. A suitable power supply may be provided with the SY50 system delivery.
Note
The Processor Unit does not contain any fans. It will be very warm, even during normal operation. This is by design. Airflow around the unit will significantly increase the effect of the heat sinks and thereby also the lifetime of the unit. Such an air flow is highly recommended.
