Description
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.
