– shorter than 50 m for PM240-2 Power Modules.
– shorter than 25 m for PM340 Power Modules.
– shorter than 100 m for Chassis Power Modules.
● The pulse frequency is
– ≤ 4 kHz for Blocksize Power Modules.
● The current ≤ rated input current in the technical data.
For Chassis Power Modules, an additional line reactor is required to achieve Category C2.
The Power Modules of Category C2 are suitable for the second environment. With an
additional line reactor with a line impedance U
PM240-2 Power Modules will meet the requirements for the first environment.
Category C1
If the requirements of Category C2 are met, the PM240-2 Power Modules will meet with the
limit values of Category C1 with external line filters. The Power Modules are intended for use
in the first environment.
Note
Intended use of external line filters
If external line filters are used, the limit values of Category C3 and/or C2 will be met with
Blocksize and Chassis PM340 Power Modules.
Whereas the use of external line filters with PM240-2 Blocksize Power Modules that already
comply with EMC Category C2 will result in compliance with the limit values of EMC
Category C1.
