The model type JVR-FF is a high production,
two DC voltage step fuseless diode
rectifier system designed to obtain
maximum production performance form
material lifting magnets. The rectifier
applies a “high" DC voltage
to minimize the magnet charge time
and the automatically drops the voltage
back to a “low”, safe
carry voltage to maximize magnet lifting
efficiency, minimize the magnet charge
time operation cycle and reduce magnet
heating. The system includes redundant
protective features to prevent locking
in the high voltage mode. An evaluation
of magnet to be operated must be made
for proper “high” and
“low” voltages and the
time function the unit is to operate
within the “higher” voltage
operating mode.
