TFY
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 sys-
tems (PLCs, CNCs, NCs, Solid State
Counters, etc.). The TFY 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 Varistor option
provides additional protection by
clamping the transients at a specifi c
voltage level (Max. Clamping Voltage).
The Bleeding Resistor allows the
voltage that builds up on the capacitor
in the TFY to bleed off after voltage
is removed. The Bleeding Resistor is
typically used in applications where
the control with the TFY may be oper-
ated (tested) without the load (motor)
connected.
