Notes: 1. From 5~100% load, nominal input, 20 MHz bandwidth oscilloscope, with 10 F tantalum and 1 F ceramic capacitors on the output. From 0~5% load, ripple and noise is
<5% Vo.
2. Measured at nominal input voltage, full load. The typical efficiencies for the chassis mount and DIN-rail mount versions are ~2% less than the board mount versions due
to the input reverse polarity protection.
3. UL approved.
4. All specifications are measured at Ta=25C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.
