DESCRIPTION
MT406 is intended for measuring and monitoring voltage in
electrical power network. Voltage input is electrically insulated
from the system by means of voltage transformer. The signal
is rectified, smoothed and amplified into an independent DC
current output.
APPLICATION
The MT406 voltage transducer is used for a permanent
monitoring of a single-phase voltage value. PLCs, PCs,
microprocessor control, indicators, alarms units etc. can be
operated by the output signal.
Voltage input can be connected either directly to low-voltage
network or shall be connected to network via a corresponding
voltage transformer (with standard 100V output).
