World’s #1 Magnet DC
Power Supply –
Kinetics Industries designs and manufactures
the highly reliable, production oriented,
"J" SPEC rectifier that
is specifically designed and rated
for demanding heavy industrial and
scrap yard applications, where short
circuits on the DC bus are common
The "J" SPEC model JVR,
exclusively designed and manufactured
by Kinetics, is ideally suited for
applications such as scrap lifting
magnets or cranes where DC faults
are a common occurrence. The JVR addresses
the problem of blown semi-conductor
fuses resulting from cut magnet cables,
shorted magnets or crane rail faults.
Listening to customers, and breaking
from traditional diode rectifier design,
Kinetics has designed and thoroughly
tested a solid state rectification
system that eliminates the expense
of silver sand fuses that conventional
designs use to protect the rectifier
The model type JVR is designed to
limit the current output of the rectifier
and trip the units AC input circuit
breaker, in the event of a "bolted
fault" on the DC bus, without
nuisance loss of fuses. The blowing
of fuses is a common lost production
time problem associated with "traditional"
fused diode rectifiers or fused rectifier
output bus designs.
After the DC bus fault has been
cleared, the JVR rectifier’s
AC input breaker is simply reset and
the unit is back in operation.
The JVR model type is comparable
in price to traditional fused rectifiers.
When the costs associated with production
down time, maintenance demands, fuses
and the need to inventory spare fuses
are added into a costing evaluation;
the JVR is a clear cost savings /
productivity increasing "winner"
for the production minded company.
