Standards

FAIL-SAFE control and safety transformer to: EN 61558 part 1 with part 2-2 and part 2-6
FAIL-SAFE voltage control and isolating transformer to: EN 61558 part 1 with part 2-2 and part 2-4

Approvals

Applications

FAIL-SAFE transformer as an isolating transformer for the safe electrical isolation of the input and output sides. The transformer may be used to set up protective separation as a protective measure in accordance with VDE 0100.
FAIL-SAFE transformer as a control transformer for electrical isolations of the input and output sides. The transformer is designed to provide control in compliance with EN 60204
FAIL-SAFE transformer as a safety transformer to secure electrical isolation of the input and output sides. By limiting the output voltage, this transformer is suitable for the construction of both SELV and PELV electrical circuits.
