The SMi2000FE, using the new Full Efficiency platform, is a ultra-high efficiency 48 VDC rectifier, fully plug & play with backwards compatibility with installed systems using rectifiers from the previous generation (SMi2000HD). With a typical flat efficiency feature higher than 96 % achieved within 30 – 70 % of load and higher than 95.5 % achieved within 25 – 90 % of load, OPEX is reduced. The ability to operate at high temperature, without de-rating, reduces or eliminates the need for expensive air conditioning with its heavy CO2 burden and high OPEX. Finally, our all-digital DSP architecture achieves very high levels of circuit integration attaining the very best in reliability.
