Features Regulated Converters 8kVDC & 10kVDC Reinforced Isolation Industry Standard DIP24 Package 3.5W Regulated Output Continuous Short Circuit Protection Wide Input 2:1 Medical Approved EN, CSA and CB Certificates 2 Pinout Options Control Pin Option Efficiency to 86% ECONOLINE DC/DC-Converter Description The REC3.5 series uses a reinforced isolation transformer to offer exceptionally high isolation of 8kVDC (4kVAC/1 minute) or 10kVDC (5kVAC/1minute) making it suitable for HT monitoring 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 recognised by CSA as reinforced isolated 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 (= "/A" or "/C"). Remote 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. 3.5 Watt DIP24 Reinforced Single & Dual Output Selection Guide Part Number DIP24 REC3.5-xx05SRW/R* REC3.5-xx09SRW/R* REC3.5-xx12SRW/R* REC3.5-xx15SRW/R* REC3.5-xx24SRW/R* REC3.5-xx05DRW/R* REC3.5-xx09DRW/R* REC3.5-xx12DRW/R* REC3.5-xx15DRW/R* Input Voltage (VDC) 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 9 - 18, 18 - 36, 36 - 75 4.5 - 9 R* = R8 or R10 for 8kVDC or 10kVDC isolation. 2:1 Input (REC3.5-S_DRW/R8(R10) xx = 4.5-9Vin = 05 xx = 9-18Vin = 12 xx = 18-36Vin = 24 xx = 36-75Vin = 48 15 117 12 145 9 194 5 350 24 145 15 233 12 290 9 388 Output Voltage (VDC) 5 Output Efficiency Max.
