1.1 Sine wave filter designation
The filter designation is structured from the output filters characteristics.
Figure 1 Schaffner sine wave filter designation
|
The first part of the designation ‘
FN5420
-xxx-yy-E_ _ _ _’ refer to the sine wave filter from
Schaffner output filter products.
|
The second part of the designation ‘FN5420-
xxx
-yy-E_ _ _ _’ indicates the current rating at
rated voltage and 50Hz (note that it can be rounded to 2 significant digits, please check the
exact value in datasheet and section 3.1 below)
|
The third part of the designation ‘FN5420-xxx-
yy
-E_ _ _ _’ indicates the filter terminal type.
For more details, please consult the datasheet and section 3.1 below.
|
The fourth part of the designation ‘FN5420-xxx-yy-E
_
_ _ _’ contains 4 slots, the first is the IP
degree of protection, second, the presence of active ventilation (fan), third the presence of a
power supply for the fan (if present) and the last one indicates the presence or not of a tem-
perature switch.
Note that only specific combinations exist, please refer to the selection tables for complete list.
