The control board affected is designed for systems with a 120 VAC primary input voltage. The incorrect transformer installed is designed for systems with a 208 VAC primary input voltage.</br> </br>Subsequent testing and risk assessment performed by TNB's sub-contractor, RBB Systems, found that under nominal input voltage, the control card operated marginally. Under low input voltage, the card could fail to operate properly, which could cause a failure of its parent component, the battery charger.</br>Per TNB, the only sale on record of the Cyberex battery charger is of eight units sold to Philadelphia Electric Company (now part of Exelon-Peach Bottom Nuclear Power Station) in 1993, which are designed for 120 VAC primary input voltage to the control board.AC primary input voltage to the control board. +
