can I use LNK457D in application were the power supply is 230Vac +-15% and in "emergency operation" the power supply may be 18x12Vdc batteries i.e. 216Vdc nominal voltage?
Thank you in advance
LNK-PL will not work in DC input. As a substitute use LYTSwtich-0. Use high input capacitance so that the output current will not change either AC or DC input.
