SINEAX U 543
Transducer for AC voltage
Camille Bauer Metrawatt AG Data sheet U 543 Le – 03.15 1
Self-powered
Carrying rail housing P8/35
Application
The transducer SINEAX U 543 (Fig. 1) converts a sinusoidal AC
voltage signal into an output signal that can serves several receiving
instruments such as indicators, recorders, alarm units etc.
The transducer fulfi ls all the important requirements and regulations
concerning electromagnetic compatibility EMC and Safety (IEC
1010 resp. EN 61 010). It was developed and is manufactured and
tested in strict accordance with the quality assurance standard
ISO 9001.
Features / Benefi ts
Self-powered / Less wiring expense
Low power consumption / Smaller CT’s can be used
Standard version as per Germanischer Lloyd
Layout and mode of operation
The transducer comprises a transformer W, a rectifi er unit G and
an amplifi er V (Fig. 2).
The measured variable is isolated from the electronic by the
transformer W, and is rectifi ed and smoothed in the rectifi er unit G
following. The amplifi er amplifi es the resultant signal and converts
it into the load-independent DC signal.
