5.9 Connecting the Power Supply Module PSM 510
5.9.1 AC Line Choke
It is mandatory to use a 3-phase AC line choke (see 5.9.1.1 Connecting 1 PSM 510 to the AC Choke and 5.9.1.2 Connecting 2 PSM 510
Modules to the AC Choke ).

[V] Inductance [mH]
PSM 510 (10 kW) 20 500 Minimum: 0.47
Maximum: 1.47
PSM 510 (20 kW) 40 500 Minimum: 0.47
Maximum: 1.47
PSM 510 (30 kW) 60 500 0.47 ±10%
If 2 PSM 510 modules are installed in parallel, use an AC choke as specified in table 15 . See 5.9.1.2 Connecting 2 PSM 510 Modules to
the AC Choke for further information.

Danfoss recommends mounting the AC line choke close to the PSM 510.
The maximum cable length depends on the cross-section, and the required voltage and current at the DC-link.
If the AC line chokes are mounted away from the PSM 510, the maximum cable distance is 5 m.
5.9.1.1 Connecting 1 PSM 510 to the AC Choke
Connect the PSM 510 to the electric grid with the correct AC choke for the power size of the PSM 510.
