Bear 1075 Variable Frequency Drive – 1075 HP / 800 kW

Compared with traditional variable speed drives, the Bear 1075 VFD series water pump dedicated variable frequency drive is more efficient and easier to install and operate. In addition, IP65 and IP20 protection level, built-in pump control and protection function into VFD, no need for extra relay, PLC, Easy wire connection, decrease troubleshooting, save raw material, maintenance, and human cost. As a result, it is an ideal variable speed pump drive for new and retrofit applications.

The Bear 1075 VFD variable frequency drive can be used with any standard AC motor, IP65 protection rating Bear 1075 VFD could install on the motor directly, no need for extra PLC, relay, contactors, and control box. The built-in application software makes it the most convenient driver for debugging, programming and operation.

The professional control and protection function for the pump and motor, the soft start and stop, incredibly improve the service life of the pump, motor, and pipe. All these features make this compact and easy-to-use drive reliable and energy-saving up to 70%, suitable for almost any application.
