Advice Electronics OPEN FRAME


are small, high grade, open frame power supplires AC/DC switchers that deliver from

200W to 600W continuous power to anything from one to four outputs.

These electronic open frame 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 product.
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 - open frame power supplires, any voltage and current combinations are available upon request.
