Notes:
RAC03-xxSC/277
Series
Note1: Measured @ 230VAC / 50Hz / Ta=25°C with constant resistant mode at full load.
Note2: If used @ 115VAC / 60Hz with full load, max. capacitive load is less, please contact RECOM for detailed information.
Note3: „Total Regulation“ is the output voltage tolerance which includes initial voltage precise, thermal drift, line regulation and load regulation at rated input
voltage and load condition.
Note4: . „Ripple & Noise“ is maximum peak-to-peak voltage value measured at output within 20MHz bandwidth at rated line voltage and output load ranges, and
with a 47 µF low-ESR electrolytic capacitor in parallel with a 0.1 µF ceramic capacitor across the output.
Note5: Start up only is guaranteed at temperatures down to -25°C. Other specifications may not be met.
