High Voltage Transducer

VariTrans P 29000

Compact high-voltage isolation amplifiers with safe galvanic isolation, VariPower broad-range power supply and genuine calibrated range selection. Working voltages up to 1000 V AC/DC and test voltages up to 5.4 kV AC, maximum performance in a compact modular housing.

High-voltage VariTrans P 29000 series isolation amplifiers are available in two input versions for a variety of requirements: high voltage, mV. The devices are ideal for monitoring and controlling electrical drive systems operated with DC voltages and feature a passive output for direct connection to a supplying PLC. Input voltages from ±100 V to ±1000 V DC are galvanically isolated and provided at the output as standard 0/4 … 20 mA or 0 …. 10 V signals or as a bipolar signal in the range of -20 … 20 mA or -10 … 10 V.

Typical applications are DC current and servo drives, generators etc, as well as power supplies for welding units and inverters for solar or wind power systems. The extraordinary performance and flexibility of the isolation amplifiers supports the user in the development of the most diverse products or system solutions.

Facts

  • Universal usability: input 20 mV to 1000 V
  • Working voltages up to 1000 V AC/DC
  • Protective separation according to EN 61140 – protection of the maintenance staff and subsequent devices against excessively high voltages up to 600 V AC/DC 
  • Test voltage 5.4 kV AC across input and output 
  • Excellent transmission properties:
    • Gain error 0.1 or 0.2 %
    • Cut-off frequency >10 kHz
    • Rise time T99 <200 µs 
  • High load capability at the output: 12 V (current output), 10 mA (voltage output) 
  • High immunity to transient common-mode interference: T-CMR >100 dB 
  • Tremendous flexibility thanks to calibrated switching of the measurement ranges; reduction in the number of models results in lower inventory costs 
  • World-wide useability with VariPower broad-range power supply 20 V to 230 V AC/DC +/–10 %;
    reliable function even with unstable supply 
  • No damage in the case of erroneous power connection 
  • Rectifier in the signal path (absolute-value forming); optional 
  • RangeLimit, adjustable lower or higher limit at the output; optional 
  • Test jacks for measuring output current and voltage 
  • Low space consumption in the enclosure with only 17.5 mm wide modular housing 
  • Low-cost installation – quick installation, convenient connection of the power supply through DIN rail bus connectors (in the case of 24 V DC supply)
