Current Transformers


  • Measures electrical current by transforming current from high to low measurable values
  • Wide primary current range of 3.5 to 800 amps
  • Applications include advanced fault-tolerant computers and workstations, control panels reading current flowing to transformers, telecom and communications systems
  • 50 Hz to 100 kHz operating frequency
  • Available totally encapsulated, with or without wound primary turns and loading resistor
  • Built to meet UL, MIL, VDE, CE specs. EMRL current transformers meet UL1244
  • Ideal for ampmeters, wattmeters, relays and cross current compensation
