Product Information

Resolution:
The Controller card on the Magnum VS stores the user settings, should this card become faulty it can be ‘hot-swapped’.
 
When the Controller Card is removed the Rectifiers in the unit default the Output Voltage to 54.5v and continue to load share until a Controller card is replaced into the unit and new settings are entered.
