DC/DC Converter
RN
Description
The RN series of compact 1.25W single output converters are especially useful when more than 1W of
power is required, but there are space restrictions than make a 2W converter unsuitable. The converter
series feature an industrial ambient temperature operating range of -40°C to +85°C without derating
and up to 100°C ambient temperature with derating. Options include 1kVDC or 2kVDC isolation and
continuous short circuit protection (/P).

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

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
