Unregulated

Converter

• Medical grade DC/DC converter

• 250VAC working, 2MOPP

• 5.2kVDC isolation for 250VAC working voltage

• -40°C up to +90°C operating temperature

• 3rd Ed. safety and 4th. Ed. EMC

Description

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%

efﬁ ciency. 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 certiﬁ ed using a simple external LC ﬁ lter. The converters are

fully certiﬁ ed to CB, IEC/EN and ANSI/AAMI 60601 third edition safety standards, RoHS2+ (10/10)

and REACH and come with a 5 year warranty.
