BEDFORD 600 Series Variable Speed Drive Controller

The Bedford 600 series is a variable speed drive to enhance the performance of single phase and three phase water pumps up to 7.5 kW.
The Bedford 600 series eliminates the requirement for large pressure tanks and pressure switches used for automatic
operation as well as associated pressure cycling.
The Bedford 600 series provides both the ability to conserve energy through only operating the pump according to the speed required to maintain constant pressure and further allowing for multiple set points to be met.
The Bedford 600 series is equipped with an easy to use LCD display and is completely designed and built for controlling pump systems from the ground up.
Mounting bracket included.

A Pressure Transducer 4-20mA, 1mPa is required for operation (sold separately)
