2:1 wide input range
3kVDC/1 minute isolation
-40°C to +70°C (full load) operating range
IEC/EN62368-1 2nd & 3rd Ed. certified
UL/CSA/CAN 62368-1 certified
Industry standard pinout (SIP8)
Low cost
DC/DC Converter
RS3E
Description
The RS3E series offers very high power density, wide input voltage range, high 3kVDC isolation, and
an industrial operating temperature range of -40°C to +70°C without derating. High efficiency, tight
regulation, and remote on/off control are just some of the characteristics of this advanced, low cost,
SIP8, 3W converter which is ideal for highly sophisticated high density power supply designs in
demanding industrial applications.
