About the 179069
The DC Bus Control PCB is located directly below the power module adapter PCB (179067) and connects to this board via vertical connectors and the power interface harness as well as the Bus Control-PMA harness. It also connects to the exterior of the open chassis via the gate driver harness.
The LiquiFlo AC Drive series have been sold under both Reliance and Rockwell Automation company names. The DC Bus Control PCB is also available as a Rockwell part with similar specifications.
LiquiFlo AC drives can be liquid-cooled and are PWM (pulse-width modulated) drives. These drives can be used for applications needing vector regulation, or as a general-purpose drive system. The 179069 DC Bus Control circuit board is designed as part of a C-Frame drive; these drives are typically open-chassis style drives with a full-load power wattage of 7000 W (fluid) or 2000 W (air). The drive can use V/Hz or Vector regulation. With V/Hz regulation the drive offers 110% continuous output current capacity. Vector regulation allows drive output to 150% for up to five seconds.
To access important information regarding the proper handling of and installation requirements for the 179069 board, please refer to original documentation from Reliance like manuals, user guides, or data sheets for this part. AX Control may have copies available if you have misplaced your original documentation. Please talk to our sales staff when you place your order.
