M500

Programmable Standard Current Transformer

Programmable Standard Current Transformer М500 and Range Extender М500E1 provides unique abilities of current ratio control in automated CT calibration systems

M500 high accuracy is achieved by using a two-stage technology and electronic compensation of burden influence

FEATURES AND BENEFITS

  • High accuracy (current error ± 0,005 %; phase displacement ± 0,15 min)
  • Rated primary current range: 0,5 … 5000 А
  • Rated secondary current: 5 А
  • Primary current values are selected using the control knob rotary encoder or by PC via the USB interface
  • Electronic burden compensation of secondary circuits
  • Possibility of using with automated CT calibration systems
  • Built-in overload protection
  • Small size and low weight

APPLICATIONS

M500 is used by:

  • Manufacturers of Current Transformers
