Custom AC Drive for a Boat Lift

KB Electronics, Inc. Manufacturer of AC Drives, DC Drives & Variable Speed Controls

Application: AC Drive for a Boat Lift

A boat lift is designed to store a boat out of the water when not in use and place it into the water when ready to be used.  Typical applications include private boats stored adjacent to lakes, rivers, or canals.  The system requires a Drive that can endure a harsh outdoor environment and contain inputs for limit switches.  The drive must also be capable of operating when wired to a GFCI circuit, must be simple to operate, and it must also contain Pass Code Protection.

KB Solution:

KB engineers selected model KBDA-27D with a custom Input/Output module.  The drive is housed in a NEMA 4X enclosure which makes it suitable for outdoor use.  It is rated for 1HP-3Ømotors and can operate from either a 115 or 230VAC line. 

Custom software was developed by KB which incorporated the specifications required for the application: 

  1. Dedicated input for high/low limit switches
  2. Tamper proof pass code system to prevent unauthorized use
  3. GFCI circuit operation
  4. Dedicated input for remote control operation

A custom front label was developed which included the customer’s logo and special functions. In addition, the drive is factory programmed for Ready to Use, “Out-of-the-Box”. Read more Case Studies on our website.
