Measuring transducer FE1883-AD
Also, this device can be called: FE1883AD, FE1883 AD, FE-1883 AD, 1883 AD EF, EF-1883AD, FЄ1883-BP FЄ1883AD, FЄ1883 BP.
Measuring transducer power three-phase networks FE1883-AD - a device for measuring three-wire and four-wire power grids AC three-phase, 50 Hz and output of results of measurements in digital form via interface RS -485. Also, the device can be used for linear power conversion (total active, reactive or total total total) in a standardized output DC signals.
Other uses converters: the control parameters of electrical installations, equipment technical diagnostics for complex automation of nuclear power plants and other industries that require the measurement and control of the parameters of three-phase networks.
Operation FE1883-BP is a three-phase network parameters determine the conversion of the instantaneous values of the input signals into digital codes and further mathematical processing.
Structurally, the converters are made in cases of difficult flammable plastic, can be mounted on boards and panels, as well as cabinets and racks on balanced tire TS 35 (standard DIN EN 50022).
The case, measuring instruments converters FE1883-BP, which is made of hard plastic fuel consists of a main body and the faceplate. Printed circuit board on which the electric circuit elements are inside. The front panel connector pin screws, LEDs "ON." And "Mode".
