The Kinetics model type BPP is
a heavy industrial, constant potential,
diode power supply with solid state
switching from a "charge"
voltage to an economizing "hold"
voltage for the operation of DC
magnetic brake or clutch coils.
Units have been designed to be space
and energy efficient for installation
and mounting within locations of
minimal footprint availability,
such as a bridge crane. The BPP
power supply incorporates a voltage
switching system from "charging"
to "holding" that eliminates
the need for energy wasting economizing
resistors and higher maintenance
DC voltage contactors. The BPP uses
the same highly successful Flux
Forcing power control scheme that
Kinetics uses in our industry leading,
JVR-FF heavy scrape lifting magnet
The BPP includes a Flux Forcing,
multi-voltage transformer, adjustable
industrial timing circuit, mill
duty AC contactors and full wave
diode rectifier mounted in a mill
duty heavy industrial enclosure.
The rectifier assembly, rated for
highly inductive loads, is protected
from voltage spikes and surge with
conservatively rated primary and
secondary MOV surge suppressors
and a DC bleed resistor across the
The Kinetics, designed and manufactured
power transformer comes "standard"
with multiple taps above and below
the nominal "charge" and
"hold" voltages to offer
the maximum application flexibility
for various brake coil ratings,
AC utility voltages and brake operating
conditions. The "charge"
and "hold" time intervals
are easily field adjusted to match
an application’s requirements.
