Controls for electromechanical feeders are VF Series (variable frequency VFD-type) and are optimized for efficient operation and allow for a full range of material flow with a 10:1 turn-down ratio. The VF Series controls are UL/CUL approved. In addition, a wide range of optional functions are available for specific control requirements:
Analog input
Digital communication
Onboard diagnostic capability
EVF series controls are optimized for efficient operation and allow for a full range of material flow with a 10:1 turn-down ratio on electromagnetic feeders. The newly designed EVF line of feeder controls operate with a single- or three-phase input providing half-wave (RC) output and are configured with custom firmware thus allowing for reduced power consumption. Additional features of the new EVF product offering include precise voltage regulation, expanded DC control signals and PC communication, and improved diagnostic capability.
