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-pass circuits.
