The DMA-1 CT is a 1-phase current intensity indicator, adapted
for measurement in an indirect circuit using current transfor-
mers with an output current of 5 A.
The sensor correctly measures the true rms value of the
current (TrueRMS), even in the case of a distorted (de-
formed) current waveform.
The indicator continuously measures the TrueRMS current value,
the result of which is shown on a 3-digit segment display on the
facade of the unit.
The indicator allows the value of connected current transfor-
mers to be set, so that the value shown on the display corre-
sponds to the actual current value.
The DMA-1 CT is suitable for mounting in a switchgear directly
on a 35 mm DIN rail.
