When referring to non-regenerative power supplies, we'll use PS-25B4
and PS-65A. They all admit a voltage range between 400 to 460 V AC.
They are:
The PS-25B4 supplies 25 kW and includes an internal auxiliary 24 V DC
power supply for the control circuits of the modular drives. The over-volt-
age and ballast alarm activation levels are the ones of the power supplies
that admit 460 V AC. The PS-65A supplies 65 kW and always needs an
auxiliary power supply APS-24 for the control circuits of the modular
drives.
