The LSIS-S100 inverter becomes innovative

LSIS S100 is set to be the replacement for the now legendary iG5A and is packed with size saving technology making it up to 40% smaller and a reduction of Side-by-Side installation from 50mm to 2mm. With the Upgraded Sensorless control, starting torque of 200%/ 0.5Hz is produced and provides adequate power for low speed applications.  The flying start function allows for smooth reaction times during power spikes or power failure conditions under load. This is achieved by applying a sensorless smoothing algorithm to estimate the speed, thus allowing for faster reactions to localised incidences that may cause damage.  From 30~75 kW the S100 has a built-in DC reactor which effectively improves the power factor and by moderating the relative intervals to conduction and non-conduction it decreases the THD (total harmonic distortion). Added is the EMC (electromagnetic interference) filter installed as standard in the 3 phase 400VAC series which reducing the electrical noise in compliance CE standard certification of 2nd Environment/ Category C3 (Class A)  With the S100’s auto-tuning function is applied in standstill or rotary tuning, allowing one to tune the drive when running and when it is standing still. With the auto-tuning one is able to help the drive to discern whether this is a heavy or light duty application. When the motor is tuned the motors performance is optimized to the maximum degree ensuring power and motor saving.  For heavy duty applications the S100 is rated at 150% of current for 60 seconds and normal operations at 120% for 60 seconds.  The S100 is also able to communicate to various fieldbus systems and has as standard, RS485 with Profibus-DP, Ethernet-IP Modbus TCP and CANopen field bus options thus making this drive very versatile for applications specific systems.  With the new look and design and the functionality of the S100 range of VSD’s, LSIS has captured the imagination and attention of many with a well packaged, versatile and fresh approach to the drive industry, setting the LSIS-S100 to become the preferred drive in the future.
