Description
EN-60950-1 Certified
UL-60950-1 Certified
EN-60601-1 Certified
Specifications (measured at TA = 25°C, nominal input voltage, full load and after warm-up)
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.
