Digistart is a multifunctional electronic starter with microcontroller. It is suitable for use on all the three-phase asynchronous induction motors, and assures :
- Starting management: All the traditional systems concerning motor starting (direct, star-delta, etc.) can draw a starting current that can vary between 7 and 9 times the motor rated current.
Digistart, can limit by simple adjustment, ina precise way, the current during the entire starting up phase.
- Protection of motor and driven machine: The starting up, the protection and the system automation imply the numerous elements installation making the electronic cabinets complex and costly. Digistart provides supplementary functions that limits the need for additional equipment with a consequent reduction in cost of material, manpower and running costs.
- Progressive stop control: The impact of harsh stops on certain low inertia applications, especially pumps, induces mechanical shocks, hydraulic disturbance or noise pollution.
Digistart, by generating a voltage at the motor terminals during the deceleration phase, extends the time taken for the motor to come to rest. |

PETER electronic is developing the VersiStart II series, a new powerful generation of soft starters offering proven quality and dependability in a slim and compact design. Because of its narrow design, the microcontroller-equipped soft starter is extremely space- and cost-saving.
The VersiStart II series can be individually programmed and thus easily adapted to customer-specific requirements. The soft starters are especially suitable for controlled acceleration and deceleration of electric motors and allow, inter alia, jerkless torque increase and current reduc-tion during the starting phase. With this new development, PETER electronic offers a low-priced alternative to star-delta starters and an intelligent solution with a high degree of functionality at low investment cost. |

These soft starters are microprocessor controlled and are designed to work with asynchronous motors connected in open delta configuration. By using this technique the soft starter can handle more power than when connected in a conventional star circuit. Motors of up to 55kW open delta (37kW star)can be controlled with this range of units.
The M300 range limits the current during start-up and so it is more efficient. All settings are made through a touch panel which incorporates an LED display.
They protect the mains supply from sags and damaging surges (transients), whilst reducing the current demand during start-up. |

ASTAT%u2122 Solid State Reduced Voltage
GE offers 3 lines of ASTAT solid state reduced voltage starters. The ASTAT SD is a line of compact, high performance three phase starters, available to 25hp @ 460v. The SD is a full functional soft starter with complete starting/stopping control and fault diagnostics. The ASTAT IBP Plus is a line of bypass solid state starters featuring a fully rated bypass contactor. These starters are rated up to 300HP @ 460v. The design is completely wired allowing quick, simple installation into either new or exisxting installations as a replacement for traditional starters. Bypass contactors are a must for enclosed installations where free air movement is not possible. The ASTAT CD Plus is the most full featured starter in the ASTAT lineup. Parameters include soft start voltage ramp, kick-start, current limiting, an energy saving feature, thermistor input, soft stop, pump control, DC injection breaking, communications, jog/slow speed and tachometer feedback.

The soft start and braking device of the VersiComb series from PETER electronic, for motor ratings up to 11KW, represents an alternative with a good cost-performance ratio in order to replace star-delta starting in combination with a d.c. braking device.
The devices of the VersiComb II type enable soft start and wear-free braking of three-phase asynchronous motors. Their advantages in comparison with direct-on-line starting or star-delta starting are a torque increase without jerk and current reduction during the starting phase.
This gives the mechanical system and the drive components a longer life.
