The SPD3303X supports three primary output modes:

• Ipo olominira: Each channel operates as a separate power supply with its own voltage ati lọwọlọwọ eto.
• Series Mode: Channels 1 and 2 can be connected in series to provide a higher output voltage (up to 60V). This mode is useful for applications requiring higher voltage than a single channel can provide.
• Ipo ti o jọra: Channels 1 and 2 can be connected in parallel to provide a higher output current (up to 6.4A). This mode is suitable for loads requiring more current.
