Principle
of operation
LEKTROMIK K2
is a module for the soft start of single-phase capacitor motors also with
separate start capacitor. Good soft start performance with a useful reduction
of starting current can be achieved.
LEKTROMIK K1 is a
snatch-free soft start module with phase-control in one of the phases. The
other two motor phases are connected directly to the supply terminals. The
voltage in the controlled phase is increased to full voltage during ramp up.
The starting torque is limited and the mechanical stress on the transmission
components drastically reduced.
LEKTROMIK KK1 and KIMODUL
DMA are soft start modules for three-phase induction motors and make use
of phase-control in two phases. One motor phase is connected directly to the
supply terminals. The voltage in the two controlled phases increases gradually
to full voltage during ramp up. The starting torque can be controlled very
finely and a good soft-start characteristic can be achieved.
LEKTROMIK KK1 is
especially suited for starting small fractional h.p.
motors.

Typical
installations
Packaging machinery – to
save stress and wear on transmission components
Long and cross travel
drives for cranes - load swing is reduced
Bottling plant in
breweries – to prevent damage to bottles
Electronic switching of
conveyor belts – no contactor wear
Parcel sorting plant –
prevents parcels from skidding, electronic switching with PLC
Pumps – hydraulic surges
are eliminated
Compressors for heat
pumps – reduction of starting current
Refrigeration compressors
– reduction of starting current
Starting wood-working
machines – reduction of starting current
Vibration transporters –
smooth starting
