VOLTCON High Voltage Isolating Converter

  • Output Proportional to RMS or DC voltage Input
  • Input-Output Isolation to 1kV
  • CE Marked for the EMC Directive
  • Compact and Highly Competitive
  • Zero and Span Adjustments

This range of isolated signal converters can accept a widerange of AC and DC voltages and provide an isolated 4-20mA output.

The device uses a true RMS input stage which allows accurate measurement of non-perfect AC waveforms.

The inputs of the device are connected directly to the power rail to be measured and the outputs, which are always in the range 4-20mA and proportional to the inputs, are connected to the data acquisition equipment. The input voltage measurements are totally isolated and protected with failsafe resistor networks.

All units offer isolation between input and output, power and input and power and output.

VCONHL-AC Ac Current Input Isolating Signal Converter

  • AC Current or Voltage inputs
  • Can also handle DC inputs
  • True RMS measurement
  • DIVIDER unit used for higher voltage inputs
  • Isolated 4-20mA or Voltage outputs
  • High Accurate but low cost unit

The VCONHL-AC can take an AC or DC Current or Voltage signal and provide an isolated 4-20mA or voltage output.

By measuring the true RMS value of the incoming waveform the VCONHL-AC can cope with waveformd from inverters or variable speed drives as well as pure sine wave signals. Typicalinputs include 0-1A or 0-5A ac signals from current transformers or 0-250Vrms voltage signals using the DIVIDER unit.

Housed in a compact DIN rail mounting enclosure the unit is a highly accurate but low cost option.

CTX AC Current Transmitters

  • CT Style Current transmitter
  • Standard or Split-ring Versions
  • DC Voltage or 4-20mA Outputs
  • User-selectable Input Range

The CTX range of Current Transformer transmitter act as standard current transformers but have a 0-10Vdc or 4-20mA output.

The range is available as standard fixed ring or split-ring versions, the split-ring allowing the unit to be installed without disconnecting the existing wiring.

Input ranges are from 0-2A ac up to 0-200A ac and eaxh unit has three user-selectable ranges, allowing for easy changes to the configuration in the field.

The CTX range has moulded case insulation to 600 Vac. The CTX are a unique low cost way of obtaining 0-10Vdc or 4-20mA signals from AC current signals.

420TWAC Current Transformer Transmitter

  • Current Transformer Input 4-20mA Output
  • Loop poweredoperation
  • True RMS AC input
  • Suitable ofr all AC waveforms
  • High Accuracy and Low Cost

The 420TWAC is a Current Transfomer input, 4-20mA output 2-wire transmitter.

The 420TWAC can take an 0-1A or 0-5A input from any standard Current Transformer and returns a 4-20mA output proporional to the True RMS of the current input.

This makes the unit suitable for all types of AC waveforms including those from AC inverters or Variable Speed Drives.

It is housed in a compact DIN rail mounting enclosure and is a high accuracy, low cost unit.
