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 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 the UL mark.
