PowerFlex

755 with OEM Liquid Cooling

Frame 6 and 7 AC Drives

PowerFlex 755 with OEM Liquid Cooling Frame 6 and 7 AC drives differ from

the standard, air-cooled PowerFlex 755 Frame 6 and 7 AC drives, respectively, in

that:

• The heatsink is replaced by a chillplate.

• Coolant inlet and outlet connections are provided for the chillplate.

• A thermal switch is added to the DC inductor.

Key features of the PowerFlex 755 with OEM Liquid Cooling AC drives are:

• Provides OEM liquid cooling at 200, 300, and 400 HP (480V) ratings and

132, 200, and 270 kW (400V) ratings.

• Provides similar input/output and overload ratings at 2 kHz PWM as the

standard air-cooled PowerFlex 750-Series AC drives (see Ta bl e 3

• Provides the same UL 508C certification and CE certifications as the

standard, air-cooled PowerFlex 750-Series AC drives.

• Maintains the same ambient air and surrounding air environmental

requirements as the standard, air-cooled PowerFlex 750-Series Frame 6

and 7 AC drives.

• Available as an IP00, NEMA/UL Type Open style that can be converted

to a NEMA/UL Type 4X/12 integrity back with a user-installed flange

kit.
