M3402R - Drive Logic Interface

- 30 to 125hp Drives -

The Bonitron M3712 is a low cost solution for powering 3-phase AC variable frequency drives from a single phase source.

For motor applications above 10hp, 3-phase motors are the only economical option. Many locations may only have single phase power available. Examples include Irrigation, Oil and Gas Pumping, and Agricultural Machinery in remote areas.

In these cases, a variable frequency drive (VFD) can be used to control 3-phase motors. VFDs offer advantages such as soft starting, speed regulation, and increased efficiency in all of these applications. Most are not designed for single phase operation, and even those that are must be oversized by up to 300% when operated from single phase.

When used in conjunction with a VFD, Bonitron M3712 Single Phase Power Supplies have the same great advantages of a 3-phase control without oversizing either the VFD or motor.
The Bonitron M3712 protects your drive from the high currents caused by single phase operation, allows your drive to run cooler, and extends the life of your drive!
