Operation
Transient Voltage Filters
TVFs are applied to circuits where
transient electrical voltage spikes can
cause a malfunction or damage in
solid state controls or control systems (PLCs, CNCs, NCs, Solid State
Counters, etc.). The TFD is typically
applied in parallel with three phase
inductive loads (motors) to absorb the
transients generated when the load
is disconnected from the line. It also
absorbs electrical noise while the load
is operating. The Bleeding Resistor
allows the voltage that builds up on
the capacitor in the TFD to bleed off
after voltage is removed. The Bleeding
Resistor is typically used in applications where the control with the TFD
may be operated (tested) without the
load (motor) connected.
