Providing 12 V output adjustable from 10.5-13.2 V, Model FPS1000-12 864 W power supplies are used for driving non-isolated point-of-load dc-dc converters in distributed power systems. They measure 1.61 x 5 x 11.4 in., can be used individually, or as many as 3 can be mounted in 1U-high 19 in. rack-mount enclosure to form N+1 redundant and hot-swap power system. Features include OR-ing MOSFET switches, 2 variable-speed cooling fans, and 0-70°C operating temperature range.

Lambda's Popular FPS1000 Line Adds 12V Hot-Swap Front End for Distributed Power Systems
SAN DIEGO, June 11, 2007 - Lambda has launched a 12-volt output version of its popular FPS1000 front-end power supplies for driving non-isolated point-of-load DC-DC converters in distributed power systems without the need for intermediate bus converters. The 12-volt output can be adjusted from 10.5 to 13.2 volts. The new 864-watt model FPS1000-12 complements Lambda's existing line of 24-, 32- and 48-volt output models.
The FPS1000-12 supplies - each measuring 1.61 x 5 x 11.4 inches - can be used individually, or as many as three can be mounted in an optional 1U-high 19-inch rack-mount enclosure to form an N+1 redundant and hot-swap power system. In addition, they have integrated OR-ing MOSFET switches that will automatically disconnect a faulty supply from the load (or from other paralleled supplies) should a failure occur.
The rack-mounted supplies can have different output voltages (e.g., 12, 24, 32 or 48-volt) when installed in the optional FPS-T1U rack - which provides separate output terminals for each supply - or supplies with the same output voltage will be connected together automatically within the FPS-S1U rack. Up to eight supplies can be combined in a current-sharing arrangement between these racks. In either case, the racks can be zero stacked, with no airspace required above or below because cooling airflow is integral to each supply, from front to rear. Each supply has two variable-speed cooling fans and can operate in temperatures ranging from 0°C to 70°C, with some derating starting at 50°C. Key applications for the FPS1000 series include communications, factory automation, and RF power amplifiers.
For system monitoring, opto-isolated signals are provided - including DC-OK, AC-Fail and Over-temperature - and front-panel LED displays indicate AC-OK, DC-OK or DC-Fail conditions. A remote On/Off control is also standard, as well as remote sense to compensate for voltage drops in the cables that connect the supply outputs to the load. Other standard features include single-wire current-share and an auxiliary 12-volt output (diode ORed). Available options include I2C monitoring of the output current/voltage, internal temperature and alarm status, and front-panel-mounted IEC320 AC power connectors.
All models in the FPS1000 series can operate from a universal 85 to 265VAC, 47 to 63Hz, or 120 to 360VDC. The units are fully RoHS-compliant, carry the CE mark, and meet UL/EN60950-1 safety specifications, as well as EN55022 level B and FCC level B EMC specifications, conducted and radiated.
The FPS1000-12 supplies are available now, with prices starting at $400 each in 100-unit quantities. More information can be found at Lambda's web site: www.lambdapower.com.
