Features • Reinforced Insulation for 250VAC Working Voltage • Clearance and Creepage Distance: 8mm • 5kVAC I/P to O/P 2MOPP Isolation • 2µA Patient Leakage Current • Industry Standard Pinout • 2:1 and 4:1 Wide Input Range Regulated Converters Description REM3 3 Watt 5 2:1 & 4:1 DIP24 Single and Dual Output 5Y 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 CE and UL marks.
