Application

The Euclid Type 4296 Lifting Magnet Controllers are suited for many uses from light scrap handling to the handling of heavy billets or plates. It may be used with all types and makes of dc lifting magnets.

Description

The Euclid Type 4296 Magnet Controllers incorporate heavy duty time proven components arranged to provide optimum control of your lifting magnets.

A mechanically rugged high thermal capacity discharge resistor assembly is permanently connected in parallel with the magnet and provides a safe discharge path for the stored magnetic energy. With Euclid magnet controllers, induced volts cannot return to the line, permitting rectified power supplies to be used without the added expenses of special protective loads or by-passcircuits.

Manual Discharge

Type Controller

The Euclid Type 4296 Manual Discharge Type Lifting Magnet Controller provides for optimum operator control over the release of magnet loads.

The Manual Discharge Type Controller is controlled via a three (3) position master switch, which places the full control of the "Lift", "Fan" and "Clean" functions directly under the control of the operator. The Manual Discharge Type of controller is best suited for applications requiring accurate load control rather than operational speed.
