Reinforced insulation for 250VAC working voltage Features Clearance and creepage distance: 8mm DC/DC Converter 5kVAC I/P to O/P 2MOPP isolation 2A patient leakage current Regulated Industry standard pinout Converter 2:1 and 4:1 wide input range REM3 Description 3 Watt The REM3 series of medical grade regulated DC/DC converters features reinforced 5kVAC/1 minute 2:1 & 4:1 isolation with low 2A 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- DIP24 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. Single and Dual Selection Guide Output Part nom. Input Output Output Efficiency Max.
