2:1 & 4:1
DIP24
Single and Dual
Output
The REM6 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.

Notes:
Note6:
Note7:
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 whole REM6 series can meet EMI Class A with no external filter. And Class B only with external components.
