Bell transformers and safety transformers allow for a very low voltage
(ELV 8 V, 12 V or 24 V) to be obtained from a low voltage network (LV 230 V).
All Schneider Electric transformers are:
b
b
safe: primary and secondary circuits are perfectly insulated by each other
b
b
resistant to short-circuit currents thanks to the built-in device.
Bell transformers: NF EN 60742, EN/IEC 61558-2-8.
Safety transformers: NF EN 60742, EN/IEC 61558-2-6.
