The Type 4292P Yardmaster Pup Controllers incorporate heavy-duty time proven
components arranged to provide optimum control of your lifting magnets. A mechanically rugged high
thermal capacity discharge varistor assembly is permanently connected in paralled with the magnet
and provides a safe discharge path for the stored magnetic energy. With Yardmaster Pup magnetic
controllers induced voltage cannot return to the line, permitting rectified power supplies to be
used without the added expense of special protective loads or bypass circuits.
