ATV31 / 312 FAN management
Transcript ATV31 / 312 FAN management
These are 1 phase chokes :
VZ1L004M010 (10mH, 4A)
VZ1L007UM50 (5mH, 7A)
VZ1L018UM20 (2mH, 18A)
It is possible to use 3 phases chokes below :
VW3 A4 551 instead of the VZ1L004M010.
VW3 A4 552 instead of the VZ1L007UM50.*
VW3 A4 553 instead of the VZ1L018UM20.*
Customer will use only one phase of these chokes as define in diagram on next page.
Rq : Like only one coil will be used we will have voltage on the 2 other coils (they will work
as a transformer).
We will have voltage on the unused coil equal to the voltage drop on the input coils (3 to
5% of the drive voltage supply).
(*) Check remark on next page
Connexion for the VW3A455x used as VZ1L0xxx
WARNING : E2, S2, E3, S3 of VW3A455x must not be connected
Remark about VW4 A3 552 & VW4 A3 553
Like we have less inductance, we will have more input line current (~5%).
