General characteristics


  • Rated power : 500 VA – 4000 VA
  • Input phase-phase voltage: < 1000 VAC
  • Output phase-phase voltage of isolating transformer: 51 V – 1000 VAC
  • Output phase-phase voltage of safety isolating transformer: < 50 VAC
  • Operation: Continuous
  • Frequency : 50-60 Hz
  • Protection class: I
  • Insulation class: B 130οC
  • Degree of protection: IP 00
  • Cooling method: Natural air circulation
  • Maximum ambient temperature: 40℃
  • Type: Dry

Advantages


  • Flexible and space-saving due to option of horizontal or vertical mounting
  • Low operating temperature due to unimpeded air circulation on all sides
  • Safe and simple cable connection achieved through the use of special terminals
  • Easy installation using special mounting supports that permit the comfortable use of tools
  • Reliability achieved through high standards of quality control carried out by state-of-the-art, calibrated instruments at all stages of production, from receipt of raw materials to inspection of final products, one by one

Isolating transformers can be used:


  • Where galvanic isolation of the load and the user from the power source (e.g. power grid) is required for protective purposes. The supply voltage can be transformed to a different value at the same time
  • When the transformer is incorporated in an electrical control panel as a component of a circuit/configuration

Safety isolating transformers can be used


  • When safe extra low voltage (SELV) is required, in addition to isolation
  • When the transformer is incorporated in an electrical control panel as a component of a circuit/configuration
  • To supply SELV rectifying circuits
