PRODUCT DESCRIPTION
The reverse energy dissipator
functions as a shunt regulator that
limits the rise in power supply
voltage, during regeneration. When
a motor is braking or a stage is
lowering, energy is transferred from
the motor to the supply capacitor
causing the voltage to increase.
In high power systems it may be
impractical to use capacitance to
absorb all the energy.The model
125 and 145 can be used to
dissipate the energy as the voltage
reaches a set limit.
Under normal forward running
conditions, the PWM dissipator is
inoperative. Only when braking
occurs, increasing the power supply
voltage does the PWM dissipator
start to dissipate energy. When the
trip point is reached the PWM duty
cycle starts to increase and energy
is dissipated over its resistive load.
As the voltage increases, the duty
cycle increases, linearly dissipating
more energy over its internally set
operating range
The range is directly proportional to
the trip voltage (4% of Trip point).
The green LED indicates power OK,
the yellow LED indicates dumping,
and the red LED indicates
overtemperature and shutdown.
For dissipating more energy
the Model 125 and 145 can be
connected in parallel for
simultaneous operation.
