QS3.241 - Power Supply

Power Supply QS3.241 SwissQprint Oryx 1

The power supply (QS3.241) is fitted to SwissQprint Oryx 1, Impala and Nyala UV flatbed printers.

It provides the machine's regulated voltages. A failed supply stops the machine.

On the unit photographed, the front panel and the rating plate identify a PULS power supply from the Dimension range, QS3 series. The rating plate shows an AC 100-240 V (±15 %), 50-60 Hz, 1.8-1 A input and an adjustable DC 24-28 V output, 3.4-3 A continuous and 5-4.5 A for 4 seconds.
