Switch Mode Power Supplies

REO builds a range of variable output DC power supplies that operate on the switch mode principle. The variable output is produced by high speed switching of the mains supply, after rectification, using IGBT's and controlling the mark space ratio. The DC level is reduced to the required output range by employing REO high-frequency transformers. Smoothing components, also manufactured by REO, are used to give a steady, ripple free DC supply.

REOTRON SMP 150/50

..................................................................................................

One of a range of switch mode, variable, DC power supplies that are produced by REO for current, voltage or power regulation. A touch panel and LED display is provided for setting up the unit. There are a number of different field bus interfaces available with these units.

The units are very compact, relative to their power output and several units can be connected together in parallel or series for higher ratings
