Description

The R1S/E series is an unregulated DC/DC converter in fully encapsulated open Frame

package style. This series has been designed to offer exceptionally high efficiency at low loads

and an extended operating temperature range. Uses include battery powered supplies, green

energy applications and general isolating/converting DC power where board space and high

efficiency is a premium.
