Note
: Transformers have an off load operating voltage that is higher than the rated voltage. For loads that
are sensitive to overloads (electro-magnetic circuits), the transformer must be made to operate at ln. After
operation of the protection device upon an overload, cut-off the power supply and let the transformer cool
down before restart.
Function
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).
Description
All Multi 9 transformers are:
n
Safe: primary and secondary circuits are perfectly insulated by each other.
n
Resistant to short-circuit currents thanks to the built-in device.
n
Class II with terminal shield (optional)
