Rectrms-3PH series coil

The RCTrms-3ph is a 3-Channel AC current transducer for permanent installation. Simple to install and easy to retrofit it combines the benefits of a thin, flexible, clip-around Rogowski (sense) coil with a signal conditioner providing accurate, true rms measurement, of AC current. The RCTrms-3ph has an industry standard 4-20mA or 0-5V output making it ideal for process control, status alarming or system monitoring purposes. Typically the RCTrms is used with SCADA systems, PLCs, data loggers

Features:

  • Easy to retrofit
  • Simple to install in applications where space is limited
  • The size of the Rogowski coil can be specified independently of the primary current
  • Does not suffer from magnetic saturation
  • Ideal for process control, status alarming or system monitoring in a wide variety of applications, from arc furnaces to power distribution.
  • CE marked
  • Complies with EMC EN 61326-1 2006
  • Complies with IEC61010-1:2001 

Specifications:

  • Traceable calibration
    • Every unit is supplied with a traceable calibration certificate
    • No magnetic materials means excellent linearity<0.1% reading
  • Fully isolated measurement
    • Isolated power supply 2kVdc
    • Coil rated at 2kVpeak (withstand test is 4kVrms /50Hz/ 60 sec)
  • Small DIN rail (or panel mount) enclosure – UL94 V-0 rated
 

Options:

  • Isolated BNC-BNC cable split option
    - Between coil and electronics to enable ease of installation e.g. threading through existing conduit. Standard cable permanently fixed.
