Chapter 1 The introduction of PR5200(C) soft
starter
1-1. The feature of the PR5200(C) soft starter
PR5200(C) series intelligent motor soft starter incorporates the latest motor control theory and
proprietary motor protection technology and advanced software technology of new equipment, it is
an ideal replacement of startup products which early used start method of “Star to Triangle
conversion”, “autoformer step-down voltage” and “magnetic control step-down voltage” ; at
present market ,Its performance is more superior than other ordinary soft starter without using
intelligent control technology.
1-2. The main function of the PR5200(C) soft starter

To reduce the motor starting current and reduce power distribution capacity, avoid
investment of expansion of power capacity.

To reduce the starting stress of the motor and the load of the equipment ; extend lifespan of
the motor and related equipments.

Its soft stop function can effectively solve the problem of parking vibration of the inertial
system,which is unable to realize by traditional starting equipment.

To have six unique start-up modes adapts to the complex conditions of motor and load, to
perfect start effect.

Has the perfect and reliable protection function; effectively protect the motor and the related
production equipment use safety.

Motor soft starter intelligence, and network technology application makes motor control
technology to adapt to the rapid development of the electric power automation technology in
higher requirements.
1-3. The main features of the PR5200(C) soft starter
