8kVDC & 10kVDC Reinforced Isolation ECONOLINE Features Industry Standard DIP24 Package DC/DC-Converter 3.5W Regulated Output Continuous Short Circuit Protection Regulated with 3 year Warranty Wide Input 2:1 Converters Medical Approved EN, CSA and CB Certificates 2 Pinout Options Control Pin Option Efficiency to 86% 3.5 Watt DIP24 The REC3.5 series uses a reinforced isolation transformer to offer exceptionally high isolation Description of 8kVDC (4kVAC/1 minute) or 10kVDC (5kVAC/1minute) making it suitable for HT monitoring Reinforced circuits, mains power meters, IGBT isolated power supplies and other sophisticated industrial and medical applications. The isolation capacitance of only 20pF makes them also suitable for low leakage applications. The isolation transformer is recognized by CSA as reinforced isolated Single & Dual with a minimum internal clearance of 2.4mm and a minimum internal creepage clearance of 4.6mm. The REC3.5 is available in two industry-standard pinouts (=/ or/). Remote Output on/off control is possible with the /CTRL option (A pinning only) and an optional undervoltage lockout function is also available (/X1 ). The converters can deliver 140% rated power for short periods of time to cope with applications with large capacitive loads or high start up currents.
