The REM3 series of medical grade regulated DC/DC converters feature 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 conditions.
The outputs are short circuit and overload protected. The converters are available in two different pin-
ning 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 CE and UL marks.

Notes:
Note1:
Note2:
Note3:
An external input filter capacitor is required if the model has to meet EN61000-4-4 or/and EN61000-4-5.
Recommended components:
5Vin
aluminium capacitor (Nippon Chemi-con KY series, 1000µF/25V) and a
reverse diode (Vishay V10P45) to connect in parallel
12Vin, 24Vin
aluminium capacitor (Nippon Chemi-con KY series, 470µF/50V)
48Vin
aluminium capacitor (Nippon Chemi-con KY series, 330µF/100V)
The REM3 (W) with 4:1 input voltage can meet EMI Class A with no external filter. And Class B only with external components.
This Power module is not internally fused. A input line fuse must be always used.
