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 Table 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
