KB Electronics case study: Custom ac drive for new boat lift

April 15, 2016 By Lisa Eitel Leave a Comment

Now, a new custom ac drive is helping make a boat lift work faster and survive longer.

A boat lift for residential use essentially takes a boat up in hoists and then stores it out of the water. That helps keep the boat — usually a private watercraft stored adjacent to a lake, river, or canal populated by residential spaces — cleaner and (in saltwater areas) out of corrosive washes.1-KB-Electronics-Sea-Monster-boat-lift-motor-controls

Typical boat lifts of this type must also endure harsh outdoor environments. Inside, typical controller units contain:

• Inputs for limit switches

• Circuitry that allows operation when supplied with power via a GFCI circuit

• Connections for a simple-to-operate interface

• Integrated intelligence for Pass Code Protection

In one newer setup for Portco Marine, KB Electronics supplied an I/O module and other hardware and software to make a more robust setup for end users.

More specifically, KB engineers picked a KBDA-27D variable-frequency drive with NEMA 4X and IP 65 protection and a custom Input/Output module.  The NEMA 4X enclosure makes the drive withstand the outdoors.  The drives are rated for 1HP-3Ø motors and can operate off either 115 or 230 Vac.

KB Electronics also developed and supplied custom software for the boat lift. The programming incorporates key specifications, including:

1. A dedicated input for remote control operation

2. Dedicated input for high/low limit switches

3. Tamper-proof pass code system to prevent unauthorized use

4. GFCI circuit operation

A custom front label includes the customer’s logo and special functions. In addition, the drive is factory programmed for immediate use with no setup — right out of the box.
