General remarks
- DO NOT put secondary windings of transformers
in parallel in order to increase the output power, as
the slightest difference in output voltage will result
in a huge current circulating in both secondary
windings (see fig.6).
- When supplying contactors or impulse switches at
low voltage, and especially when several devices
can be operated simultaneously (i.e. impulse
switches with centralised command), care should
be taken to correctly size the step-down
transformer.
Text for specifiers
- All transformers have the CEBEC - IMQ - VDE
approval marks.
- All transformers have their nominal output power
available on all different output voltages.
- All transformers are protected against short-
circuits. A direct short-circuit on the secondary
winding will not result in a permanent damage due
to excessive heating.
- All transformers have double isolation with an
isolation voltage between the primary and the
secondary winding of at least 3.75 kV.
- The transformers are cast resin.
- The captive Pozidriv cage terminals have a
capacity of 1 to 16mm
2
.
- The terminals guarantee a solid, reliable
connection.
- The protection degree of the transformer is IP20.
- All transformers are modular and DIN-rail
mountable.
- The transformers are all equipped with a
transparent circuit indicator.
