Prototype
The prototype was made ba souldering the components on to a pcb board. The power converters passed the first test while unhooked from the system.
When testing powerconverters with the entire ROV the 48 - 12 V power converter capitulated. We heard a noise when we applied voltage and immediately turned it off.
The fault occured in the UWE Murata component.
PCB - Order
The new PCB has been ordered from EASY EDA with presouldered capacitors and resistor.
