Isolating transformers
Special network configurations require an upstream isolating transformer. Like the AMP8620 power supply modules, this supplies a short-term peak current of 100%. Full input power is not required for many applications. If this is the case, isolating transformers with a lower power rating can also be used.

The power supply modules are assigned to the isolating transformers in the following tables.
Single-phase supply
Module | Nominal input current [A] | Isolating transformer | Nominal output current [A] |
|---|---|---|---|
AMP8620 | 10 | AX2090-TT80-0003; | 10 |
Three-phase supply
Module | Nominal input current [A] | Isolating transformer | Nominal output current [A] |
|---|---|---|---|
AMP8620 | 23 | AX2090-TT80-0016; | 23.1 |
