Does the VDI-32 meet the ABYC A-28 standard and continue to provide a ground path even if one or both diodes have failed?
asked
Is the VDI-32 galvanic isolator a failsafe design?
Conjectures from someone with an elec background -
I'm not Victron nor a design engineer of galvanic isolators - If the diodes fail I suspect you'll lose the ground path (at least at time of failure). The diodes have to be placed in the ground path for the concept to work.
Now, whether device is able to detect the failure and indicate that failure, or put it into a failsafe state and bypass, I don't know. If I had to guess, I don't see any LEDs on the VDI-32 casing, so my guess would be no.
fyi, ABYC just put out an email saying that's now a new online course on galv isolators.
Thanks, but I'm looking for confirmation from somebody with direct knowledge. FYI, the Mariner Pro-safe does not have indicator lights but is a failsafe design.
