DC/DC-Converter
with 3 year Warranty
The RO/E series is an unregulated DC/DC converter in standard SIP4 package style.
This series has been designed to offer exceptionally high efficiency at low loads, an
extended operating temperature range and low deviation (10% to 100% load).
Uses include applications with restricted energy budget and industrial applications
where a high efficiency level is required.
