Description
The REC8-xxxxSRW/DRW-series offer single and dual regulated outputs in a DIP24 package with
2kV or 3kV isolation options and are suitable for higher power industrial or medical applications.
Remote on/off control is standard and SMD pinning is offered with the /SMD option.
The converters can deliver 150% rated power for short periods of time to cope with applications
with large capacitive loads or high start up currents.

use /H3 for 3kVDC Isolation (not SMD)
* add suffix “/SMD” for SMD package, e.g.
REC8-2405SRW/H2/A/M/SMD
* add suffix -R for Tape and Reel packaging (only
available for SMD package)
