| The EMA acquisition unit is an accurate
RMS current and voltage meter that can monitor up to 5 voltage and current
channels. The EMA is designed to work with loads controlled by SCR Power
controllers using firing modes such as Phase Angle, Burst Fired, Single
Cycle and Advanced Single Cycle. |
The measurements are available on
the front panel display and remotely via digital communications. Each channel
has programmable alarm functions that can be set up via a software configuration
program. A Windows® based software tool is provided for custom display
configurations. |
