Notes:
1. From 5~100% load, nominal input, 20 MHz bandwidth oscilloscope, with 10 µF tantalum and 1 µF ceramic capacitors on the output. From 0~5% load, ripple and noise is
<5% Vo.
ꢀ. Measured at nominal input voltage, full load. The typical efficiencies for the chassis mount and DIN-rail mount versions are ~ꢀ% less than the board mount versions due
to the input reverse polarity protection.
ꢁ. All specifications are measured at Ta=ꢀ5°C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.
