capacitors reforming
Capacitors, if left for more than 1 year without power tend to degrade (recoverable) to a point that they may possibly explode (it does happen) if a full DC voltage is suddenly applied. The capacitor reforming circuit gently re-introduces the capacitors to voltage, you leave the forming unit attached 1 hour for every year without power.
