Notes:
Note3: standard part is without continuous short circuit protection
add suffix „/P“ for continuous short circuit protection
Note4: add suffix „/H“ for 2kVDC/1s isolation
or add suffix „/HP“ for continuous short circuit protection and 2kVDC/1s isolation
Ordering Examples:
RO-123.3S/P: 12VDC Input Voltage, 3.3VDC Output Voltage, Single Output with continuous short circuit protection
RO-0509S/HP: 5VDC Input Voltage, 9VDC Output Voltage, Single Output with 2kVDC/1s Isolation and continuous short circuit protection

Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max Cap Load is tested at nominal input and full resistive load and is defined as the
capacitive load that will allow start up in under 1s without damage to the converter
