Rockwell Automation Liqui-Flo AC Power Modules - Manual (Page 14)

2-2 LiquiFlo AC Power Modules, Hardware Reference Version 6.4
Table 2.1 – Power and Enclosure Ratings
* With V/Hz regulation, 110% continuous output current capability. With vector regulation, 150% output current capability for 5 sec.
**Note that LiquiFlo drives are rated for use with water at specified temperatures and pressures as the coolant. Some coolant fluids may
allow an increased output rating while others may require the output to be derated. The LiquiFlo drive is also capable of running at 4 kHz
or 8 kHz. Contact Reliance Electric for ratings.
2.2 Enclosure Ratings
LiquiFlo drives have the following enclosure rating:
• Open-Chassis Style: Intended to be installed in an enclosure.
LiquiFlo drives must be placed in an enclosure.
