Note2: If used @ 115VAC / 60Hz with full load, max. capacitive load is less, please contace RECOM for detailed information. Note3: The “output voltage tolerance“ includes initial voltage accuracy, thermal drift, line regulation and load regulation at rated input voltage and load conditions. Note4: “Ripple and Noise“ is the maximum peak-to-peak voltage value measured at the output with a 20 MHz bandwidth, at rated line voltage at full load. Note5: Start up only is guaranteed at temperatures down to -25°C. Other specifications may not be met.
