The REC7.5-xxxxSRW/DRW-series offer single and dual regulated outputs in a DIP24 package
with 1kV, 2kV or 3kV options and are suitable for higher power industrial or medical
applications. Remote on/off control is possible with the /CTRL option and SMD pinning is
offered with the /SMD option. 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.

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter.
The REC 7.5 series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.
