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.
