The RPS5012 power supply is made to work safely and reliable within the range of 100 V up to 240 V AC @ 50 to 60 Hz. We strongly recommend to avoid any supply voltages out of that range.

In case of excess voltage the RPS5012 will shutdown. After disconnecting the power supply from the excess voltage, the protection circuit is reset and the RPS5012 is ready to resume work. 

Due to tolerance in electrical components the exact voltage leading to shutoff is unpredictable.
