Open Frame 200W-600W Power Supply

The eF 175/300/400 and eFO600 series are are small, high grade, open frame AC/DC switchers
that deliver from 200W to 600W continuous power to anything from one to four outputs.
These power supplies incorporate active power factor correction and 85-264VAC universal input,
making them ideal for use worldwide.

The eF 300/400 and eFO600 series is built in a 6.8"x 3.86" 1U configuration.
The eF 175/200 series is built in a 5"x 3" 1U configuration.
The DP 200/300/400 series of DC/DC switchers is especially configured for the Telecom market.
Built-in ORing diodes for 1:1 and N+1 redundancy configurations are part of our standard

The eFO series of AC/DC switchers is also available with internal ORing diodes, allowing for
redundancy and hot-swap applications.

Very high efficiency and power density results from the use of advanced component and circuit
technologies such as synchronous rectification, low profile transformer and SMT components.
Flexibility as a concept- the eF series provides design engineers with a power platform that is
flexible enough to meet any design requirement. In addition to the current product offering, any
voltage and current combinations are available upon request.
