DIP24
Single and Dual
Output
The REM10 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
conditions. 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 UL mark.

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)
