European Approvals - ENEC

KEMA File Numbers updated December 2003

Talema demonstrate superior technical expertise by being the only toroidal transformer manufacturer in the world to have a "General Approval" of power transformers to EN61558.

Through working closely with KEMA our engineering teams have the unique ability to design custom power transformers, within agreed design constraints, which are immediately approved by KEMA to EN61558 and EN60950.

 

These "Families" may be divided as follows:
Non Short-Circuit Proof - Isolating Transformers

Non Short-Circuit Proof - Safety Isolating Transformers

Non Inherently Short-Circuit Proof - Safety Isolating Transformers

 
2060938.02 : Non Short-Circuit Proof - Isolating Transformers

As the name implies, these Isolating transformers provide electrical isolation between input and output circuits, and rely on external IEC127 fuses to provide overload protection of the secondary windings.

  • Up to 6 primary windings

  • Up to 10 Secondary windings

  • Maximum total power rating: 3000VA

  • Maximum Input voltage : 440V

  • Maximum Output voltage : 250V

2060938.03 : Non Short-Circuit Proof - Safety Isolating Transformers

These Safety-Isolating transformers provide electrical isolation between input and SELV output circuits, and rely on external IEC127 fuses to provide overload protection of the secondary windings.

  • Up to 6 primary windings

  • Up to 10 Secondary windings

  • Maximum total power rating: 3000VA

  • Maximum Input voltage : 440V

  • Maximum Output voltage : 50V (SELV Limit)

2060938.01 : Non Inherently Short-Circuit Proof - Safety Isolating Transformers

These Safety-Isolating transformers provide electrical isolation between input and SELV output circuits, and rely on an internal "thermal switch" to provide overload protection.

  • Up to 2 primary windings

  • Up to 2 Secondary windings

  • Maximum total power rating: 300VA

  • Maximum Input voltage : 240V

  • Maximum Output voltage : 50V (SELV Limit)

IEC 950 Approvals

As well as power transformer approvals to IEC 950 / EN60950, Talema also have an approved range of ISDN S Interface modules, fully certified to IEC 950 / EN60950 Supplementary level.

 

Other Approvals

Through Talema's close communications with European standards authorities, we have numerous custom-designed products carrying various European approvals, such as:

  • VDE

  • KEMA

  • CEBEC

  • SEV

  • NEMKO

  • DEMKO

  • SEMKO

  • UL

  • CSA
