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
Modules to the AC Choke).
Table 14: Line Choke Characteristics for 1 PSM 510
Model
PSM 510 (10 kW)
PSM 510 (20 kW)
PSM 510 (30 kW)
If 2 PSM 510 modules are installed in parallel, use an AC choke as specified in
the AC Choke for further information.
Table 15: Line Choke Characteristics for 2 PSM 510 installed in parallel
Model
PSM 510 (2 x 30 kW)
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.
