48Vdc Input, 30Vdc@20A Output Full-brick
DC-DC Converter AGF600-48S30
Description
The AGF600-48S30 is a single output DC-DC
converter with standard full-brick outline and
pin configuration. It delivers up to 20A output
current with 30V output voltage. Above 94.0%
ultra-high efficiency and excellent thermal
performance make it an ideal choice to supply
power to power amplifier in telecom RF
application. Aluminium baseplate structure
makes it possible for the module to work under
-40°C ~ 85°C without air cooling.
