Electrical Features

Motor Assembly

•Continuous service fractional horsepower DC motor.

•Hall Effect sensor transmits RPM to microprocessor control

•115/1/60 supply voltage

Controller Features

•Closed-loop control constantly monitors feedback from the auger motor RPM sensor for high accuracy and repeatability. Feed rates remain stable during main power supply voltage fluctuations.

•Remote control mounting capability permits mounting the control panel up to 9 feet from the feeder.

•Field-programmable display permits viewing in rpm, pounds per hour, kilos per hour, etc., as well as high/low limits.

•Automatic and manual/calibration operation modes.

2-4 Options

Options marked with “*” indicate options that can be factory installed or retrofitted in the field.

Special Voltage
