Lambda offers 12-volt hot-swap front-end for distributed power

ILFRACOMBE, England, 18 May 2007. Lambda in Ilfracombe, England, is introducing a new version of the FPS1000 front end power supply with a nominal output voltage of 12 volts for driving non-isolated point of load DC-DC converters directly in systems with a distributed power architecture without the need for intermediate bus conversion.

ILFRACOMBE, England, 18 May 2007. Lambda in Ilfracombe, England, is introducing a new version of the FPS1000 front end power supply (related product) with a nominal output voltage of 12 volts for driving non-isolated point of load DC-DC converters directly in systems with a distributed power architecture without the need for intermediate bus conversion.

The model has found immediate favor with manufacturers of non-telecommunications equipment that do not require a 48-volt bus, yet wish to move to a distributed power system.

The FPS1000-12 has integrated O-ring MOSFETs and is capable of being hotswapped, and so is suitable for those requiring N+1 redundancy. With opto-isolated signals -- such as DC OK, AC, Fail, and over-temperature warning -- FPS models offer easy system monitoring.

Front panel indicators are fitted for AC OK, DC OK, and DC fail. Remote on-off switching is supported, as is remote voltage sensing to compensate for voltage drop in the cables that connect the supply to the load.

Other standard features include output voltage trimming (10.5 to 13.2 volts for the FPS1000-12) and auxiliary 12 volts output (diode Ored). Options are available for I2C interface and front panel mains inputs if required.

As many as three FPS units can be fitted into the standard 1U 19-inch rack type FPS-S1U which commons the outputs together and up to eight supplies can be combined in a load sharing arrangement between racks.

An FPS-T1U rack that feeds the outputs from each module to separate terminals is available for customers who wish to configure systems with more than one voltage or to series outputs.

The racks can be zero stacked with no airspace required above or below because cooling airflow is from front to rear. For more information contact Lambda online at www.lambda-europe.com.
