BANG SSsssss

In an attempt to trim the voltage up to 13.2 on the DC-dc converter output a mistake was made.  The result being two blown slave modules in the DC-dc convertor.

The system has 4 main parts, 3 modules on the left, and the motherboard (MB) on the right.  As it turns out the three modules on the left are the same, BUT one has a short removed.  The left most (labeled M) is the master and via a signal back to the MB the other two modules run in slave mode.

In the first system we received the master was in the middle position, when we attempted to TRIM the left position nothing happened.  To diagnosis the issue the buss bars were removed from the output despite it clearly stating on the cover not to.  The result was unregulated output from the two slaves and BANG PSssssssss.

A new (used) system has arrived and been confirmed to be assembled in the proper order.   For the mechanical in mind the user manuals were not clear, but the VICOR staff have been very patient and attentive.  Thank You Vicor for the support of an old piece of equipment, and Parts2GO for again providing a working unit.

The current dilemma is how to prevent the DC-dc from outputting more than 100A to bring the battery up to 13.2V.
