Description
The REM3 series of medical grade regulated DC/DC converters features reinforced 5kVAC/1 minute
isolation with low 2µA leakage and are 60601-1 3rd Ed. certified for 250VAC continuous working. The
compact DIP24 package offers tightly regulated single and dual outputs, even under no-load condi-
tions. The outputs are short circuit and overload protected. The converters are available in two different
pinning options and optionally with an external control pin for standby consumption as low as 12.5mW.
The converters are fully certified to CB, IEC/EN and ANSI/AAMI standards and carry the UL mark.

Note2: Blank for Standard 2:1 Input Voltage Range; „W“ suffix for 4:1 Input Voltage Range
Note3: „A“ suffix for A pinning; „C“ suffix for C pinning, for more details refer to Package Style and Pinning
Note4: „CTRL“ suffix for control pin option, for A pinning only, for C pinning not available
Examples:
REM3-0512D/A = 2:1 Input, 4.5-9Vin, ±12Vout, pinout „A“, without control pin
REM3-1215S/C = 2:1 Input, 9-18Vin, 15Vout, pinout „C“, without control pin
REM3-4815SW/A/CTRL = 4:1 Input, 36-75Vin, 15Vout, pinout „A“ with control pin
REM3-243.3SW/C = 4:1 Input, 9-36Vin, 3.3Vout, pinout „C“, without control pin
