500W convertor breaks 90% efficiency
barrier
A combination of original thinking and leading-edge patented technology has resulted in a market-leading full-load efficiency of over 90% for a full-brick 500W DC/DC convertor.
A combination of original thinking and leading-edge patented technology has resulted in a market-leading full-load efficiency of over 90% for a 500W DC/DC convertor in the industry-standard "full-brick" size (116.8 x 61.0 x 12.7mm) This major advance has been achieved by the use of integrated magnetics, full H bridge transformer with soft switching and current-doubler rectifier, which means that the Advanced Power Conversion APC500 redefines power efficiency levels available to embedded systems designers

Convertors step up to higher voltages
The APC500 is a 500W "full brick" DC/DC convertor that supplies compact, high-efficiency conversion (typically better than 90%) from lower DC voltages up to higher voltage output.
External supply promises long reliable life
Low-noise multipurpose power supply is fitted with field replaceable fan and air exhaust filters making it ideal for harsh and industrial environments.
DC/DC convertor is made for LED lighting
Wide input range DC/DC convertor provides a constant-current single output for powering a single LED or an array of up to nine devices.
The innovative topology is one of the few that supplies continuous input and output current without additional filtering and can be produced in volume.
With an outstanding power density of 5.53W/cm3 (90W/in3) the APC500 also employs fixed frequency operation of 300kHz that can be synchronised to an external clock for noise sensitive circuits and helps with the design of EMC filters.
A host of features and previously unavailable intelligence are packaged within the APC500 and include accurate "brick wall" output current limit with foldback output current limit for short circuits, hot plug capability, remote sensing, remote shutdown and single wire connection for parallel operation to provide true N+1 redundancy and a simple route to kilowatts of compact DC power.
Apart from a comprehensive range of inbuilt protection features incorporating overvoltage protection and short circuit protection, the APC-F501 has some unique functions such as a thermal monitoring voltage which can provide early warning of system fault.
