Maestro Power Supply (Switched mode) - SSE

Go to content
The SSE Switched Mode Power Supply product was designed to replace the existing SSE Power Supply. It improves over the previous design in terms of improved operating efficiency, lower heat generation and intelligent monitoring.

The new design has the ability to communicate its current state in real time to the attached Maestro CPU, giving a user the ability to monitor and log voltages and currents as well as battery and AC state. It also adds cost flexibility by allowing different internal OEM PSU units to be selected depending on application requirements. Finally the new power supply was designed to be easier and quicker to manufacture and service.
