Front-end supply simplifies distributed
power
Front end power supply has nominal output voltage of 12V for driving nonisolated point of load DC/DC convertors without the need for intermediate bus conversion.
Lambda has launched a new version of its popular FPS1000 front end power supply with a nominal output voltage of 12V, ideal for driving nonisolated point of load DC/DC convertors directly in distributed power architecture systems without the need for intermediate bus conversion The new model, which complements the existing line up of 24, 32 and 48V models, has found immediate favour with manufacturers of nontelecomms equipment that do not require a 48V bus yet wish to move to a distributed power system

Lambda UK has launched a new version of its FPS1000 front end power supply with a nominal output voltage of 32V.
General-purpose power supplies boost efficiency
The LS50, LS75 and LS100 have 88 to 264V AC inputs, while the LS150 is switch-selectable for 115 or 230V AC, minimising the cost.
Power supplies cater for short-term peaks
Units provide a very cost and space efficient solution compared with oversizing conventional power supplies just to handle the peak current.
The FPS1000-12 integrates ORing MOSFETs and can be 'hot swapped' in systems requiring N+1 redundancy.
With a full array of optoisolated signals (DC OK, AC fail, overtemperature warning) all 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 13.2V for the FPS1000-12) and auxiliary 12V output (diode ORed).
Options are available for I2C interface and front panel mains inputs if required.
Up to three FPS units can be fitted into the standard 1U 19in 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.
All models have wide-range inputs suitable for operation from 85 to 265V AC at 47 to 63Hz, and 120 to 360V DC.
FPS1000 is compliant with UL/EN60950-1 for safety, and conforms to EN55022 level B and FCC level B for EMC performance. Request a free brochure from Lambda ...
