The REM1 complements the existing board-mount REM3, REM6 and REM10 series by offering
a 1W medical grade unregulated DC/DC converter in a more compact SIP7 package. The REM1
features reinforced 5.2kVDC/1 minute isolation and 2MOPP/250VAC working voltage. The REM1 is
available with 3.3, 5, 12, 15 or 24V inputs and offers 3.3, 5 or 12V outputs with up to 85%
efficiency. The operating temperature range is -40°C up to +90°C. The converter is Class B EMC and
60601-1-2 (4th Ed.) medical EMC certified using a simple external LC filter. The converters are
fully certified to CB, IEC/EN and ANSI/AAMI 60601 third edition safety standards, RoHS2+ (10/10)
and REACH and come with a 5 year warranty.
