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.
