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.
