APPLICATION
Measuring transducer MI408 converts sinusoidal AC current signal into proportional DC current signal. The analogue output signal is appropriate for regulation of analog and digital devices, computer inputs, processing and electroenergetic systems, etc.
TECHNICAL DATA
INPUT: Input current, IN (meas. range end value): Measuring range limit values 0…1 A to 0…7.5 A Nominal frequency fN: 50/60 Hz Frequency range: 45…65 Hz Own consumption: < 2 VA Overload capacity: according to EN 60688: 1992 Measured Number of quantity applications (IN) 1.2 x IN 20 x IN 5 Duration of one application continuously 1s Interval between two successive applications 300 s
LAYOUT AND MODE OF OPERATION
According to the block diagram (Picture 1), the transformer (A) serves for the galvanic separation between measuring input and signal output as well as adaptation of the input signal to the rectifier unit (B). In the low – pass filter (C) a signal proportional to the input level will be achieved.
