EMBSIN 281 G Power factor transducer

Transcription

1 EMBSI 8 G Carrying rail housing MBS/SP Application The transducer EMBSI 8 G (Fig. ) measures the power factor between current and voltage of a single or 3-phase balanced network having a sine wave form. The output signal, in the form of a load independent DC current or voltage, is proportional to the power factor between the measured quantities current and voltage. The transducer fulfi ls all the important requirements and regulations concerning electromagnetic compatibility EMV and Safety (IEC 00 resp. E 6 00). It was developed and is manufactured and tested in strict accordance with the quality assurance standard ISO 00. Features / Benefits Measuring input: Sine, rectangular or distorted wave forms of input quantities with dominant fundamental wave Measured variables ominal input current ominal input voltage Measuring range limits Power factor 0. to 6 A 0 to 60 V Min. span 0 el Max. span 360 el Measuring output: Unipolar, bipolar or live zero output variables Measuring principle: Measurement of the zero crossing interval AC/DC power supply / Universal Alternatively as marine version per Lloyd s Register of Shipping Table : Base versions ominal frequency of inputs: 0 Hz Measuring range: 0. cap ind 0. cosϕ Output: Proportional cosϕ Power supply: 8 30 V/DC or 0 00 Hz The following transducer versions are available as base versions.
