HD Feeder Controls

Introduction

DPH Engineering is an Authorized Distributor for HD Feeder Controls. These controls for electromechanical feeders are VF Series (variable frequency VFD-type) controls. These controls are optimised for efficient operation and permit a full range of material flow with a turn-down ratio of 10:1. Controls from the VF Series have received UL and CUL approval. In addition, a broad variety of optional functions can be selected to fulfil certain control requirements, including the following: analogue input digital connection onboard diagnostic capability Controls from the EVF Series are designed to maximise operational effectiveness and provide a turn-down ratio of 10:1 for electromagnetic feeders, which enables them to accommodate a wide variety of material flow. The newly designed EVF series of feeder controls functions with a single- or three-phase input and provides a half-wave (RC) output. Additionally, these controls are customised with unique firmware, which enables a reduction in the amount of power that is consumed. Precision voltage regulation, increased DC control signals and PC communication are some of the additional capabilities that are available with the new EVF product offering. Additionally, diagnostic capability has been enhanced.
