2.2 Regenerative power supplies
When referring to regenerative power supplies, we'll use XPS-25 and XPS-
65. They all admit a line voltage between 400 (1-10 %) V AC and 460 (1+10
%) V AC and can return power back to mains. They are:
The XPS-25 supplies 25 kW and can return 20 kW to mains. It integrates
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-65 supplies 65 kW and can return 54 kW to mains. It integrates
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.
