Note: Efficiency
and input current are measured at nominal input voltage and full load.
Other input to
output voltages may be available. Please contact factory.
The minimum input
voltage and starting voltage of ST and HST models are 1VDC higher than those
of DIP package due to input reverse polarity protection function.
Efficiencies for ST
and HST models are decreased by 2.5% due to the input reverse polarity
protection circuit.
