Application
MT408 is intended for measuring and monitoring singlephase electrical power network. Current input is electrically insulated from the system by means of current transformer. The signal is rectified, smoothed and amplified into a DC current output.
The MT408 current transducer is used for a permanent monitoring of a single-phase current value. PLCs, PCs, microprocessor control, indicators, alarms units etc. can be operated by the output signal. Current input can be connected either directly to low-voltage network or shall be connected to network via a corresponding current transformer (with standard 1 A or 5 A output).
