The REM5E series of medical grade regulated DC/DC converters feature reinforced 250VAC
continuous working isolation with >8mm creepage/clearance. The compact DIP24 package offers
industry standard pinouts with tightly regulated single/dual outputs and UVLO, SCP, OCP and OVP.
The operating ambient temperature range is from -40°C to +80°C without derating. The converters are
UL marked and certified to CB, IEC, EN and ANSI/AAMI 60601 3rd. Ed. Safety and 4th Ed. EMC medical
standards. The low 1µA leakage current makes them suitable for medical B, BF and CF applications.
