Voltage AC Transducer Transducer for alternating voltage. Types for rectified mean value alternatively for True RMS. 1) U400 self-powered, voltage  U400 is a self-powered transducer for the measurement of alternating voltage. The transducer measures rectified mean value and shows effective value at sine wave-form. Works without auxiliary supply and has galvanic separation between in- and output. The transducer is either enclosed for DIN-rail or module for 19" rack mounting.    ●DIN-rail - / 19" rack mounting  ●Self-powered   ●Galvanic separation 
    
2)U30 for voltage,(self-powered, module box)   U30 is a self-powered transducer for the measurement of alternating voltage. The transducer measures a rectified mean value and shows effective value at sine wave-form.Works without auxiliary supply and has galvanic separation between in- and output.    ●Singleside terminal   ●Module box, 3 modules   ●Small dimensions   ●Self-powered   ●DIN-rail mounting   ●Galvanic separation 
    
3)U480 for voltage, power supply 
  U480 measures alternating voltage. The transducer measures rectified mean value and shows effective value at sine wave-form. With auxiliary power and galvanic separation between input, output and power supply.    ●DIN-rail - / 19" rack mounting   ●Galvanic separation 
    
4)U40 for voltage, with power supply 
  U40 measures alternating voltage. The transducer measures rectified mean value and shows effective value at sine wave-form. With auxiliary power and galvanic separation between input, output and power supply.    ●Module box, 4 modules   ●Singleside terminal  ●Small dimensions   ●Galvanic separation   ●DIN-rail mounting   ●Universal AC/DC up to 250 V AC/DC 
    
5)U420 (True RMS) Transducers  U420 measures not sinusoidal AC voltage. The transducer is either enclosed for DIN-rail mounting or module for 19" rack mounting.    ●True RMS   ●Galvanic separation  ●DIN-rail - / 19" rack mounting
    
6)U424 with suppressed final range U424 measures alternating voltage with suppressed final range. The transducer has two  amplifiers; one for extended range near zwro for high resolution and one for a suppressed range up to nominal voltage.    ●DIN-rail / 19" rack mounting   ●With suppressed final range   ●Galvanic separation 
    
7)U484 with suppressed final range   U484 is designed for earth fault voltage e.g. 0-15 V. For the measurement near suppressed zero, but withstands 110 V continuous nominal voltage.    ●DIN-rail - / 19   ●Earth fault voltage, withstands 110 V   ●Galvanic separation 
    
8)U425 with suppressed initial range 
  U425 measures alternating voltage with high resolution at the nominal voltage. The transducer has two amplifiers; one for extended range near the nominal voltage and one for a suppressed range to zero.    ●DIN-rail - / 19" rack mounting   ●With suppressed initial rane   ●Galvanic separation
