Technical Information
LINE FILTER SK CIF-323-40 Part No. 276997071
Overvoltage filter – CSA filter
Technical characteristics:
Voltage limitation filter pursuant to CSA 22.2 No. 14-5 / UL508C Ch. 48 for reduction of a
5 kV surge pulse (rising edge 1.2 µs/trailing edge 50 µs) to max. 300% of the amplitude
of the rated voltage (230 VAC/240VAC for SK CIF 323 40).
CAUTION!
Module SK CIF-323-40 must be used in combination with a suitable mains choke only
(L
min
= 3 x 0.73 mH). The permanent current flowing through the choke must not be less than the
resulting typical input current of the connected frequency inverter(s).
When using a single-phase frequency inverter (SK 2xxE-XXX-123-…) L1 and also L2/N must be
wired to a choke. To do so, you can use a 2-phase (L
min
= 2 x 0.73 mH) or a 3-phase input choke
(L
min
= 3 x 0.73 mH).
Note
With the use of a line choke, the effective input currents of the frequency inverters reduce to
approximately the values of the output currents, depending on inductance and load. Several
frequency inverters can be connected to a choke/filter combination. When doing so, the sum of input
currents must not exceed the rated/nominal current of the filter and/or the choke.
Area of application:
Frequency inverter SK 5xxE-250-323-A … SK 5xxE-112-323-A
SK 2xxE-250-123-A … SK 2xxE-111-123-A
SK 2xxE-250-323-A … SK 2xxE-401-323-A
It is also possible to connect several frequency inverters to an appropriate filter. In this case, the resulting typical input current
(see technical data of FI) is definitive.
