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

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

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.
