2.2 Regenerative power supplies
When referring to regenerative power supplies, we'll use XPS-25 and
XPS-65. They all admit a mains voltage between 400-10% and 460+10%
V AC and can return power back to mains. They are:
The XPS-25A supplies 25 kW and can return 20 kW to mains. It inte-
grates an auxiliary 24 V DC power supply to feed the control circuits of
the modular drives. Consequently, it will not need an APS-24 to perform
this function.
The XPS-65A supplies 65 kW and can return 54 kW to mains. It inte-
grates an auxiliary 24 V DC power supply to feed the control circuits of
the modular drives. Consequently, it will not need an APS-24 to perform
this function.
