Technical content

Features

  • VFD and SCR waveforms current measurement
  • True RMS output
  • Panel mounting
  • Eliminates insertion loss
  • Insulated plastic case recognized according to UL94-V0 Advantages
  • Large aperture for cable up to Ø32mm
  • High isolation between primary and secondary circuits
  • Easy installation

Applications

  • VFD Controlled Loads VFD output indicates how the motor and attached load are operating.
  • SCR Controlled Loads Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives faster response than temperature measurement.
  • Switching Power Supplies and Electronic Ballasts True RMS sensing is the most accurate way to measure power supply or ballast input power. Application domain

Page 2/3 Safety This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturer’s operating instructions. Installation and maintenance should be done with main power supply disconnected. The operator must have an accreditation to install this material. Caution! Risk of electrical shock When operating the transducer, certain parts of the module can carry hazardous voltage (e.g. primary conductor, power supply). Ignoring this warning can lead to injury and/or cause serious damage. The user must take care of all protection guarantee against electrical shock. This transducer is a built-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used.

  • General tolerance ±1 mm
  • Primary aperture ∅ 32.0 mm
  • Panel mounting 4 holes ∅ 4.6 mm
  • Distance between holes 70.0 mm & 78 mm (see above dimensions) For panel mounting, replace M4 screws by new one (not supplied) with appropriate length to panel ´s thickness. Remarks
  • VOUT is positive when IP flows in the direction of the arrow.
  • The return busbar and primary conductor elbow must be located at least at 2.5 x window length more far away from the transducer case.
  • The temperature of the primary busbar can not exceed 90 °C.
  • Dynamic performances are the best with a primary busbar completely filling the primary aperture.
  • This is a standard model. For different versions (supply voltages, different outputs, bidirectional measurements...), please contact us. Ip Is OUT +24VDC GND Ip Is OUT +24VDC GND Dimensions DHR-C10 (in mm. 1 mm = 0.0394 inch) 4.60 22.28 6.80 6.808.30 2.50 4.60 733.80 8.30 25.60 Connections
