Motor Suppressor Delta Filter
Motor Suppressor Delta Filter
    In a delta suppressor
    capacitors are connected
    between the live neutral
    and earth terminals. As
    the frequency of the
    R.F.I. rises the
    impedance of these
    capacitors falls thus
    attenuating the R.F.I. at
    the mains terminal.It can
    be used for radio
    suppression of small
    electric motors and
    domestic appliances.
    Connect as close as
    possible to the source of
    interference.Specifications

Transient Suppressors Suppressor 250VAC
Transient Suppressors
Suppressor 250VAC
    These devices are simply
    connected directly across
    the power supply. They
    have a very high
    resistance up to the Vm
    voltage shown in the
    table below and therefore
    usually may be ignored
    but the moment a
    transient spike appears
    on the supply line which
    exceeds Vm the impedance
    of the device drops
    immediately to a very low
    level while it dissipates
    the unwanted energy.
    Choose the suppressor to
    have a Vm voltage equal
    to or above the voltage
    of the power supply it is
    to be connected across.
    For example both
    Suppressor 250Vac and
    Suppressor 275Vac can be
    connected directly across
    the UK mains
    supply.Please note that
    the use of AC in the
    description is simply an
    indication of its most
    likely use. Both types
    can be used equally in AC
    or DC circuits up to the
    Vm stated. Current
    ratings are for a typical
    transient pulse where
    peak current is reached
    in 8micros and the pulse
    has decayed to 50 of its
    peak value after a
    further 12micros. It is a
    standard method of rating
    these devices and is
    usually described as an
    820micros current wave
    rating.For voltage
    transient suppressors
    with low clamping
    voltages and near
    instantaneous response
    times see Table 21 in
    Semiconductors Section.
