Precision Current Transformers

Introduce:

DM series precision current transformers can be used to test, control, display and record the operation of electrical equipment and protect the equipment from damage.

DM can also be used in matching mine transformers.

Features:

  • The DM series of current transfomer are convenient for mounting in many ways.
  • The most current transformer need the special mounting and the DM series used,the mounting of DIN typing without a lot of time.
  • The protective cover for the terminal block used the switching device with safety and quick.
  • Compact design .Built in hinged terminal cover .
  • Primary current from 15A to 300A.

Applications:

  • Current measurement, monitoring and piotection for electrical wiring and equipment.
  • Current and power measurement for electric motors,lighting,air compressor,heating and ventilation system,air-condition equipment and automation-control system.
  • Current,power and energy monitoring device.
  • Relay protection device.
