S3-Wrd-3, N3-Wrd-3A Active/Reactive Power (WATT/VAR) Transducer

          ACTIVE/REACTIVE POWER (WATT/VAR) TRANSDUCERFEATURES:Accuracy: ± 0.2% RO.Watt,  Var  packaged  in  one  casePrecision  measurement  for  unbalance systemPrecision  measurement  even  for  distorted  waveHigh  impulse  &  surge  protection (5KV)The case can be mounted on a 35mm rail which complies with DIN 46277DESCRIPTIONModel:      S3-WRD-1    1φ2W,  WATT/VAR    S3-WRD-3    3φ3W,  WATT/VAR    S3-WRD-3A    3φ4W,  WATT/VARModels that can be exchanged:    N3-WRD-1    1φ2W,  WATT/VAR    N3-WRD-3    3φ3W,  WATT/VAR    N3-WRD-3A    3φ4W,  WATT/VAR    S(T)3-WRD-1    1φ2W,  WATT/VAR    S(T)3-WRD-3    3φ3W,  WATT/VAR    S(T)3-WRD-3A    3φ4W,  WATT/VARA wide  range  of  transducers  to  measure all  forms  of  WATT,  VAR,in  both  balanced  and    unbalanced,  single  or  3 phase  system. Theyutilize the well prove "time division multiplication" method of measuring instantaneous power over a wide range of input waveforms. The circuit diagram  shown  measured  voltage  is  modulated  by  circuit  of    anoscillator.  Square  wave  pulses  from  a  multi-vibrator circuit, with  a    mark - space ratio varied by the measured voltage and amplitued by the measured current, are fed to an integrator an output amplification circuit. The dc signal produced is then directly proportional to power input - Watt & Vars.The models of this series are as follows: ProductModel No.AC current transducerN3-AD-1AC current transducerS3(T)-AD-1AC current transducerS3-AD-1single phase voltage transducerN3-VD-1single phase voltage transducerS3(T)-VD-1single phase voltage transducerS3-VD-1AC current transducerN3-AD-1SAC current transducerS3(T)-AD-1SAC current transducerS3-AD-1SAc voltage transducerN3-VD-1SAc voltage transducerS3(T)-VD-1SAc voltage transducerS3-VD-1SPower controllerN3(T)-∑WR(S)Power controllerS3-∑WR(S)Power controllerS3(T)-∑WR(S)Frequency transmitterNS-FDFrequency transmitterS3-FDFrequency transmitterS3(T)-FD3 phase 3 wire reactive & current transducerN3-RAD3 phase 3 wire reactive & current transducerS3(T)-RAD3 phase 3 wire reactive & current transducerS3-RADthree phase AC current transducerN3-AD-3three phase AC current transducerS3(T)-AD-3three phase AC current transducerS3-AD-3three phase Ac voltage transducerN3-VD-3three phase Ac voltage transducerS3(T)-VD-3three phase Ac voltage transducerS3-VD-33 phase 3 wire Power factor transducersN3-PD-33 phase 3 wire Power factor transducersS3(T)-PD-33 phase 3 wire Power factor transducersS3-PD-3Negative sequence current transducerN3-AND-33 phase 3 wire var-hour transducerS3-RHD-33 phase 3 wire var-hour transducerN3-RHD-33 phase 3 wire var-hour transducerS3(T)-RHD-3Reactive power transducerS3-RD-3SReactive power transducerN3-RD-3S3 phase 3 wire  var & var-hour transducerS3-RHR-33 phase 3 wire  var & var-hour transducerN3-RHR-33 phase 3 wire  var & var-hour transducerS3(T)-RHR-33 phase 3 wire var transducerS3-RD-33 phase 3 wire var transducerN3-RD-33 phase 3 wire Phase Angle transducerS3-UD-33 phase 3 wire Phase Angle transducerN3-UD-33 phase 3 wire Phase Angle transducerS3(T)-UD-33 phase 3 wire watt-hour transducerS3(T)-WHD-33 phase 3 wire watt-hour transducerN3-WHD-33 phase 3 wire watt-hour transducerS3-WHD-33 phase 3 wire var transducer(2 output)S3(T)-WD-3S3 phase 3 wire var transducer(2 output)N3-WD-3S3 phase 3 wire var transducer(2 output)S3-WD-3S3 phase 3 wire active & current transducerN3-WAD3 phase 3 wire active & current transducerS3(T)-WAD3 phase 3 wire active & current transducerS3-WAD3 phase 3 wire unbalanced load watt & var transducerS3-RD-3(3T)3 phase 3 wire unbalanced load watt & var transducerN3-RD-3(3T)3 phase 3 wire unbalanced load watt & var transducerS3(T)-RD-3(3T)3 phase 3 wire  watt & watt-hour transduceS3(T)-WHW-33 phase 3 wire  watt & watt-hour transduceN3-WHW-33 phase 3 wire  watt & watt-hour transduceS3-WHW-33 phase 3 wire unbalanced load watt transducerN3-WD-33 phase 3 wire unbalanced load watt transducerS3(T)-WD-33 phase 3 wire unbalanced load watt transducerS3-WD-33 phase 4 wire Power factor transducersN3-PD-3A3 phase 4 wire Power factor transducersS3(T)-PD-3A3 phase 4 wire Power factor transducersS3-PD-3ANegative sequence current transducerN3-AND-3A3 phase 4 wire var-hour transducerS3-RHD-3A3 phase 4 wire var-hour transducerN3-RHD-3A3 phase 4 wire var-hour transducerS3(T)-RHD-3A3 phase 4 wire var transducer(2 output)S3-RD-3AS3 phase 4 wire var transducer(2 output)N3-RD-3AS3 phase 4 wire var transducer(2 output)S3(T)-RD-3AS3 phase 4 wire  var & var-hour transducerS3-RHR-3A3 phase 4 wire  var & var-hour transducerN3-RHR-3A3 phase 4 wire  var & var-hour transducerS3(T)-RHR-3A3 phase 4 wire  var transducerS3-RD-3A3 phase 4 wire  var transducerN3-RD-3A3 phase 4 wire  var transducerS3(T)-RD-3A3 phase 4 wire Phase Angle transducerS3-UD-3A3 phase 4 wire Phase Angle transducerN3-UD-3A3 phase 4 wire Phase Angle transducerS3(T)-UD-3A3 phase 4 wire watt-hour transducerS3(T)-WHD-3A3 phase 4 wire watt-hour transducerN3-WHD-3A3 phase 4 wire watt-hour transducerS
