1  Working principle

CNPS-DNJ AC/DC dual-purpose electric torque sensor transmitter AC and DC rated input 1000A ~ 2000A, rated output DC DC0~5v or DC0~20mA or 4~20mA. As the isolated AC and DC current of the main loop system of 1200v and below, the working power supply DC±12V~±15V or single power supply +12 V ~+24V, measuring bandwidth DC~20HZ, measuring arbitrary waveform, the maximum power consumption is +40mA, -20mA , response time ≤ 300ms, measuring aperture ¢ 50mm, output can provide standard DC current signal for long distance transmission.

2  Feature

The clamp type is easy to install, and it is not necessary to remove the bus bar. In special cases, it can be installed online without power failure.

  • Terminal wiring is easy to install ·Insulation of primary and secondary sides
  • The true rms conversion (TRMS) is used for AC measurement, and it can also be used in the case of waveform distortion.

Guaranteed measurement accuracy · Excellent long-term stability without cumulative error

  • Good temperature characteristics (≤0.04%°C)·Overload capacity is 10 times of rated value
  • Highly reliable MTBF: 2 x 104 hours · Fully enclosed for use in harsh environments
  • Thin-thin design, small size, light weight ·Complete magnetic circuit protection
  • Superior performance / price ratio · Advanced SMT surface mounting technology

3   Application field
