The
EMS series are high power switch mode AC to DC power supplies for
applications where high efficiency, precise regulation and a high
degree of packing density and light weight are required.
This series of high frequency switching power supplies is designed
to operate as a source of constant current/constant voltage with
automatic crossover. All EMS Power Supplies are fully
programmable via an analog programming or (optional) RSTL digital
interface, allowing for systems integration to meet your specific
requirements.
The EMS series represents an important element in our broad line
of switching power supplies. Beginning in 1969 with multiple
patents awarded, Lambda Americas has continued to invest in the
development and engineering of the EMS series. Successful
applications include semiconductor processing, medical, scientific
and research laboratories. The EMS series offers the best of
customer tested and application proven features, while
incorporating the latest advancements in technology for the user
of power conversion systems. |
