Application
Telecommunication, office equipment, industrial machines
and electronics, automation, robotics, household equipment.
General Description
In response to market demands for "distributed power” ETA have
developed a new DC/DC converter, suitable for PCB mounting. The
open board design of this series resulted to a lighter weigh, lower
cost and smaller size. This is an industries pin configuration. Wide
input voltage range covers 8VDC to 32VDC and 18VDC to 72 VDC.
Features
