Switching power supplies show their flexibility

The eFO800 is a new family of high density switching power supplies that can deliver from 600 to 800W continuous power output depending on configuration.

The eFO800 is a new family of high density switching power supplies that can deliver from 600 to 800W continuous power output depending on configuration.

The market leading power density is made possible by very high efficiency synchronous rectification topology, implementation of advanced components and low profile magnetics and a high degree of surface mount assembly.

This combination of state of the art design and technology means the dimensions of the eFO800 are just 229 x 102 x 80mm, and it will fit in a 2U rack shelf.

Two input options are available, universal AC (85-264V AC) with active power factor correction and 48V DC.

The main output features remote sense and all units include ORing diodes allowing single wire current sharing for increasing output power or n+1 redundant operation.

The power supply has control signals for power-good and inhibit for systems integration.

Full international safety agency approvals, UL, cUL and CE have been attained.

Over 60 models are available from a single output 5V DC at 100A to eight outputs over the range 2.5 to 48V DC.

The eFO800 is a continuation of the "flexibility" series and may be configured to nonstandard, customer specific output voltages with ease.

The power supplies are internally fan cooled and will operate at full power over the temperature range -5 to +50C.

Reliability is calculated at better than 300kh, according to Belcore TR-NWT-000332, issue 6.

Melanie O'Connor, General Sales Manager of Gresham comments: "The eFO800 is a unique product which will offer our customers an unprecedented amount of power in a very small space".

"We are constantly being asked for more power from smaller footprints and unusual output voltages".

"I am sure that this new addition to our 'flexibility' range will be a best seller".

Typical applications for the eFO800 series include industrial systems, process control, telecomms etc.
