DIGISTART, the electronic controller from, LEROY-SOMER, for induction motors, integrates the latest technological changes including an optimized bypass function. Digistart is available in two ranges adapted to market requirements: 1) D2 range, 18 to 200 A compact starters; 2) D3 range, 23 to 1600 A advanced controllers.
Economy and compactness Use of the bypass offers significant savings: 1) 4% reduction in consumption at steady state; 2) no forced ventilation; 3) 1 to 2 ratings less for dimensioning purposes.

Its operating principle is as follows: The power electronics are used to perform start-up and thus limit the current draw of the induction motor. Then it is shunted at the end of the starting phase by the internal bypass. The control electronics are still used to protect and control the motor up to the stopping phase.
DIGISTART proposes this series bypass, thus enabling additional savings on the external contact and its implementation. The DIGISTART compactness considerably reduces the overall installation weight and volume.
DIGISTART is ideal for upgrading existing installations, and enables the linking of delta connection motors, which advantageously replace a star/delta start-up, and uses the 6 motor power supply cables. Additionally, this enables a saving of at least one rating size in controller dimensioning.
Simplicity The intuitive DIGISTART navigator enables simple adjustment of the current ranges or limitations. The operator has immediate access to preset configurations for the pumping, ventilation and conveying functions, etc...
DIGISTART facilitates installation monitoring by enabling the user to: 1) access the time-dated log of failsafe actuation operations, events, consumption and operating conditions; 2) have traceability of parameter changes; 3) simulate operation by forcing the control-command; 4) view the input/output state; 5) manage reports on operating time, number of start-ups.
Flexibility DIGISTART can operate with 200-440 V, 200-575 V or 690 V three-phase networks. It can also control several induction motors coupled in parallel as well as a collector ring motor. Available on D3 (ratings 360 to 1600 A), the power inputs and outputs may be installed on request above and/or under the starter, according to the layout of cables in the cabinet. DIGISTART thus optimizes installation in the cabinet. The available field bus modules are: Modbus RTU, port USB, DeviceNet and Profibus.
Perfectly mastered electronic control DIGISTART proposes the latest electronic control technology: start-up and stopping self-adapted to load, automatic optimization of parameters by machine learning from start-ups. It also includes a slow-down curve dedicated to pumping applications resulting from 15 years of LEROY-SOMER´s experience and know-how. The possibility of operating with only two operational power units, deactivation of protection to ensure forced operation (smoke extraction, fire pump) makes DIGISTART the solution adapted to the requirements of sensitive installations.
DIGISTART offers overall protection with: 1) permanent thermal modelling for maximum motor protection (even in case of power supply cut-off); 2) failsafe actuation operations, on adjustable power thresholds; 3) control of current phase imbalance; 4) monitoring of motor temperature and the environment by CTP or PT 100; 5) optionally, failsafe actuation of the installation following earth faults as well as protection against network over- and under-voltages.
With DIGISTART, LEROY-SOMER proposes compact, economic, high performance and communicating controllers, which are better integrated into industrial installations and enable substantial savings to be made.

The new product generation is based on the technical advances made in LED production, improving the efficiency by up to 47%. The 2nd generation of the 10W arrays has four distinguishing features in this regard: they are compact, lightweight, economical and significantly brighter than before.
Sharp has retained the dimensions of 15 x 12 x 1.6 millimetres unchanged, along with an aluminium ceramic plate as carrier material. The flat surface of the ceramic plate and the soldering points already in place make it possible to attach the modules to a suitable heat sink, without too much effort or additional connecting material, thereby achieving efficient heat dissipation.

Depending on the module, the new types offer a light output of up to 900 lumens, a luminous efficacy of up to 106 lm/W in standard operation, high CRI values of 82 and a long service life of 40,000 operating hours at an operating temperature of up to 90°C. The new generation is specified for use with a forward voltage of 17.7 V and a forward current of 480 mA. But the arrays can also be operated using a current of up to 800 mA, whereby values of up to 1300 lm can be reached. With the shades "Natural White", "Warm White", and "Pure White", the colour temperatures of the new white light LED arrays are in the range of 3,000 to 5,000 Kelvin.
The extensive range of LED lighting arrays allows Sharp to provide numerous marketable solutions for the use of LEDs as light sources for lamps and lighting fixtures. The luminous Mini Zeni LED modules from Sharp are suitable for numerous applications, e.g. spot lighting and for use in LED retrofit lamps, etc.
Initial samples are available in the colour temperatures of 3000 and 4000K. These can now be ordered from Sharp sales offices and distribution partners across Europe.
