Lambda Electronics Launches FPS1000-48 Power Supplies

Lambda Electronics Inc. (San Diego, CA) launched its new FPS1000-48, the first in a series of 1,000 W power supplies whose low profile and hot-swap capability make them suitable for N+1, redundant applications. The series is available with an I2C interface that monitors key functions – a requirement for remotely situated systems.

Rated at 48 V/21 A, the FPS1000-48 accepts a wide range of input voltages – from 85 Vac to 265 Vac – and contains active power-factor correction circuitry to meet EN61000-3-2 standards. It meets Class B EMI standards – radiated and conducted – with an earth leakage current of less than 1.1 mA at 265 Vac. Three FPS1000-48 units fit into an optional 1U-high, 19 in wide shelf, for a total system power of 3,000 W; individually the units measure 1.61 in x 5 in x 13.8 in. Up to eight supplies can share a single bus, with a selectable address setting included in the shelf.

The power supplies operate in temperatures ranging from 0 °C to 50 °C full load, and are cooled by internal variable-speed fans. All models are RoHS-compliant, carry the CE mark, and conform to UL60950-1 and EN60950-1 standards. The FPS1000-48 is available now, priced at $400 in 100-unit quantities.
